Disard cache when checking checksum: This will slow down checksum checking but does not thrash cache.
Compat with libuv 0.11 (Unstable): Fixes #241
Drop WinMessageDigestImpl: The algorithms the CryptProv on Windows supports does not currently include SHA-224, so there is a "dark spot" in this implementation. Also on Win XP < SP3, most of the SHA-2 family is not actually supported. All other implementation provide support for MD5, SHA-1 and all of the SHA-2 family, hence drop the incomplete WinMessageDigest implementation in favor of any other supported implementation (at least the internal implementation is always available at compile-time).
Add --pause-metadata option: This option pauses downloads created as a result of metadata download. There are 3 types of metadata downloads in aria2: (1) downloading .torrent file. (2) downloading torrent metadata using magnet link. (3) downloading metalink file. These metadata downloads will generate downloads using their metadata. This option pauses these subsequent downloads.
Improve compiler/platform/libs information in logs: Add and use usedCompilerAndPlatform(). This adds compiler information to INFO logs and the --version output, and may be helpful when trying to diagnose/reproduce user-reported problems. Also make INFO logs include usedLibs() output. Closes #235.
Fix use-after-free on exit with multi-file torrent download + DHT: DefaultPieceStorage may be referenced by one of DHT task (e.g., DHTPeerLookupTask), after RequestGroup was deleted, and even after RequestGroupMan was deleted. DefaultPieceStorage has a reference to MultiDiskAdaptor which calls RequestGroupMan object on destruction. So when DHT task is destroyed, DefaultPieceStorage is destroyed, which in turn destroys MultiDiskAdaptor. DHT task is destroyed after RequestGroupMan was destroyed, MultiDiskAdaptor will use now freed RequestGroupMan object, this is use-after-free.
Fix bug that zero length file is not opened when flushing cache: This bug was only seen when MultiDiskAdaptor was used.
Support PREF_DIR change for Metalink files: Reworked previous commit adeead6f0396e2f8551d1182972e277728fd6c8b, and now support changing PREF_DIR for Metalink downloads.
Fix assertion failure when dir option of paused HTTP/FTP download is changed: When the directory is changed via aria2.changeOption RPC method, we directly change first FileEntry's path using FileEntry::setPath(). If there is no PREF_OUT option is given, basically file name is unknown, so we just set empty string and let the next run determine the correct file name and new directory is applied there. But previous code does not reset length property of FileEntry, so the unexpected code path is taken when unpaused and its path expects path is not empty string. This commit fixes this issue by setting length to 0 using FileEntry::setLength().
Save session only when there is change since the last serialization: This is a slight optimization not to cause useless disk access. This only applies to saving session automatically (see --save-session-interval). aria2.saveSession and serialization at the end of the session are always performed as before. When serialization, we first check that whether there is any change since the last serialization. To do this, we first calculate hash value of serialized content without writing into file. Then compare this value to the value of last serialization. If they do not match, perform serialization.
Fix (unknown length) downloads larger than 2GiB: Closes #215.
Fix F_PREALLOC based allocation on some OSX versions
Use index.html as filename for conditional-get when file is missing in URI: Previously we disabled conditional-get if file part is missing in URI. But we use constant string "index.html" in this case, so we can do the same to determine the modification time. In this patch, if we have file part in URI, we are not going to set absolute file path in FileEntry, since it prevents content-disposition from working.
Always add README.html to dist_doc_DATA: rst2html is required to produce README.html from README.rst. We include generated README.html to distribution. And rst2html is not required when compiling sources in distribution and always README.html is available.
Validate token using PBKDF2-HMAC-SHA1: This change should make token validation more resilient to: - timing attacks (constant time array compare) - brute-force/dictionary attacks (PBKDF2). Closes #220.
Add --disable-websocket configure option
mingw32: Enable wintls and compile with GMP: By enabling wintls, we can use Windows certificate store to validate server's certificate. Previously, we built windows build using openssl and since we don't bundle CA certificates, aria2 fails to validate server's certificate unless user setups their CA certificates. GMP provides fast big integer calculations, whic is used in BitTorrent encryption.
AppleTLS: Enable BEAST mitigations in ST: Only available in 10.9+, but since we might be building on a previous version but running on 10.9+, always try to set the option.
WinTLS: Accept chains with no revocation information: This is kind what browser do anyway (IE, Firefox, Chrome tested), what AppleTLS does, what GnuTLS does and what OpenSSL does. Actually, most browsers will also be OK with the CRL/OCSP provider being offline. WinTLS will still fail in that case. Should revocation information be available in the trust chain (CRL or OCSP) the certificate still will be checked! "Real" CAs, aka. those provided by the OS or system CA bundle, usually provide revocation information and are thus still checked. It should be mostly (only?) custom (organization) CAs that lack revocation information, but those users might want to use aria2 in their intranets and VPNs anyway.
Fix GnuTLS 2.x compatibility. Closes GH-216.
AppleTLS: Use newer, non-deprecated API in 10.8+

Make configure argument meaning more consistent and obvious.
Most other software uses --disable/--without for features it does build or at least check by default.
Allow for out-of-tree Sphinx builds
Bring back datetime in console log
Run checksum check if -V and -c are used and file is completed
With -c option, aria2 can continue download after the existing file position. If it is not completed, then after completion aria2 runs checksum checking if available. But if existing file has already been completed, then CreateRequestCommand exits without issuing checksum checking. And aria2 treats it download error because it needs checksum verification but it has not been done. This change fixes this by properly checking download state and issue checksum checking before CreateRequestCommand.
Support for gzipped -i and --save-session
Saved sessions may very large, as in hundreds and even thousands of megabyte when dealing with large queues. Add support to save and reload sessions to gzipped files, when libz is available.
The session serializer will output gzipped contents when the file ends with .gz, while the input file reader (UriListParser) will accept whatever is thrown at it.
Document -i/--save-session gzip behaviour
Do not use a virtual varargs function
This stuff breaks in some compiler (configurations)
Check for sys/signal.h and/or signal.h
mingw-w64 does not actually have sys/signal.h, while OSX currently has a broken signal.h Better check the presence of both and use sys/signal.h if present, else signal.h
Hygiene: Fix some clang warnings, mostly unused private members.
Fix bustage on OSX with ./configure CC=cc CXX=c++ (clang)
Do not reference RequestGroups longer than necessary
There is an initial vector of SharedHandle to seed the DownloadEngine. This vector was however kept alive via main.cc -> MultiUrlRequestInfo up until the program exits, hence effetively leaking all initial RequestGroups and associated object instances.
Hence, as a matter of dirty-workaround, drop the contents of that initial vector as soon as it is not required any longer.
Detect console with on Windows
Fix infinite loop when size of downloadResults_ exceeds maxDownloadResult_
Support BitTorrent UDP tracker
It shares UDP listening port with IPv4 DHT. At the moment, in order to enable UDP tracker support, enable IPv4 DHT.
Show correct end byte in error message when HTTP response range is not ok
Previously, unless HTTP pipelining is enabled, end byte in that message is always 0. With this change, it shows correct end byte sent to the HTTP server.
Add Portuguese manual
This translation is based on aria2 version 1.15.2 manual. Contributed by Gilberto dos Santos Alves
Fix bug that active downloads are not saved with --save-session-interval
Change aria2 configure options so that:
--enable-*: do not build by default, unless --enable specified
--disable-*: check and build by default, unless --disable specified
--with-*: do not use by default, unless --with specified
--without-*: check and use by default, unless without specified

New in aria2 1.16.3 (Feb 4, 2013)

New in aria2 1.16.1 (Dec 27, 2012)

mingw32: Re-open files with read-only mode enabled on seeding
On Mingw32 build, if aria2 opens file with GENERIC_WRITE access right, some programs cannot open the file aria2 is seeding. To avoid this situation, re-open files with read-only enabled when seeding is about to begin.
Save gid option with --save-session option
Added --gid option:
This option sets GID manually. aria2 identifies each download by the ID called GID. The GID must be hex string of 16 characters, thus [0-9a-zA-Z] are allowed and leading zeros must not be stripped. The GID all 0 is reserved and must not be used. The GID must be unique, otherwise error is reported and the download is not added. This option is useful when restoring the sessions saved using
--save-session option. If this option is not used, new GID is generated by aria2.
Use 64 bits random bytes as GID:
This change replaces the current 64 bit sequential GID with 64 bits random bytes GID in an attempt to support persistent GID. Internally, the GID is stored as uint64_t. For human representation and RPC interface, GID is represented as 16 bytes hex string. For console readout, 16 bytes are too long, so it is abbreviated to first 6 bytes.When querying GID in RPC calls, user
can speicfy the prefix of GID as long as the prefix is shared by more than 1 GID entries.
Fixed BitfieldMan::getOffsetCompletedLength overflow on 32-bit systems
mingw32: Use HANDLE only for MinGW32 build Changed console readout, making it more compact "SIZE:" is removed because it is obvious. SEEDING, SEED, SPD and UP are now replaced with SEED, SD, DL and UL respectively.
Compact readout when more than 1 simultaneous downloads are going on If more than 1 simultaneous downloads are going on, use more compact format in readout. Currently, at most 5 download stats are displayed.
util::abbrevSize() is rewritten to support "Gi" unit and provides more compact abbreviation.
Console color output:
Log level and download result string is now colored.
Logger: Simplified console output and change level format in log
The date and time are now removed from console output. The log level is now formatted as "[LEVEL]".
Start to find faster host before the number of missing segments becomes 1
The old implementation starts to find faster host when the number of missing segment becomes 1. Because of --min-split-size option, before the number of missing segment becomes 1, the number of connection becomes 1 and it can be slow. In this case, we have to wait until the last segment is reached. The new implementation starts to find faster host when the remaining length is less than --min-split-size 2, to mitigate the problem stated above.
Removed warning when --file-allocation=falloc is used in MinGW32 build The warning was just a mistake. SetFilePointerEx + SetEndOfFile actually allocate disk space.
Write data in 4K aligned offset in write with disk cache enabled This greatly reduces disk activity especially on Win + NTFS. Not so much difference on Linux.
mingw32: Removed FSCTL_SET_SPARSE set
Added --disk-cache option:
This option enables disk cache. If SIZE is 0, the disk cache is disabled. This feature caches the downloaded data in memory, which grows to at most SIZE bytes. The cache storage is created for aria2 instance and shared by all downloads. The one advantage of the disk cache is reduce the disk seek time because the data is written in larger unit and it is reordered by the offset of the file. If the underlying file is heavily fragmented it is not the case.

New in aria2 1.16.0 (Dec 3, 2012)

New in aria2 1.15.2 (Sep 3, 2012)

This release fixes several critical bugs. It also adds new features such as TLS SNI and CORS support. The --file--allocation option now take another value trunc. The new option --enalbe-mmap was added. aria2 now uses system-wide SSL/TLS certificates by default, which eliminates the requirement to specify --ca-certificate option.
Changes:
Catch exception from Socket::getPeerInfo() when pooling connection. Socket::getPeerInfo() may fail if its TCP connection has already disconnected. In this case, we log this error. The success or failure of pooling connection should not affect the later execution of the program. This bug may cause segmentation fault if Socket::getPeerInfo() throws exception during pooling connection after successful tracker request.
Fixed assertion error if --retry-wait is used. In CreateRequestCommand, if Request object returned from getRequest() is still sleeping, CreateRequestCommand pools it back but still holds its reference. This makes assertion error in UnknownLengthPieceStroage::hasMissingUnusedPiece() from AbstractCommand::execute().
Added new file allocation method called 'trunc'. --file-allocation option can now take new value 'trunc'. 'trunc' uses ftruncate() system call or platform-specific counterpart to truncate a file to a specified length.
Use int64_t instead of off_t. Using off_t, at least, in DiskAdaptor layer is problematic because torrent can contain under 2GiB files but total sum of those files may exceed 2GiB limit, which makes off_t overflow in 32 bit system without large file support. So we use int64_t in API. We'll check the file length before download so that it does not exceed max off_t.
Added TLS SNI support.
Rewritten timegm replacement function. The algorithm is based on Python 2.7 calendar.timegm.
Use system-wide certificates for SSL. Use system-wide certificates for SSL. For GnuTLS it requires the latest version, 3.0.20. OpenSSL had it for longer. This means that if SSL library is properly configured to locate system-wide certificates store, the user don't have to use --ca-certificate option. Also packagers don't have to use --with-ca-bundle configure option. Patch from Cristian Morales Vega
Fixed base64::decode() return "" if input ends with garbage and no padding.
Changed default Peer ID prefix. The new Peer ID prefix is "A2-$MAJOR-$MINOR-$MICRO-", where $MAJOR, $MINOR and $MICRO are the major version, the minor version and the micro version respectively. For instance, 1.15.2 release of aria2 will use "A2-1-15-2-".
Don't percent-decode filename value in Content-Disposition. We only percent-decode filename* value in Content-Disposition because the encoding is fully specified. But since filename value is not, so we just accept it as is.
Don't sum in-flight piece which does not intersect filtered ranges. When calculating completed length, don't sum the completed length of piece which does not intersect filtered ranges.
Fixed segmentation fault when logger failed to open log file.
Added ARIA2_STATIC precious variable to configure option. To build statically linked aria2 binary, give ARIA2_STATIC=yes to configure, like this: $ ./configure ARIA2_STATIC=yes
Use PRId64 for int64_t format specifier
Handle the case when MINGW32 vsnprintf returns -1. MINGW32 vsnprintf returns -1 if output is truncated. Increased buffer for vsnprintf in WinConsoleFile and fmt.
Added --enable-mmap option. If this option is used, map files into memory using mmap(2). This option is experimental.
Added CORS preflight request support in RPC interface. This change is based on the patch from binux.

Changes:
Updated Chinese (Simplified), Spanish, French and Russian translations. Thanks to all translators.
Updated Russian man page. Thanks to ITriskTI.
Ignore peer which possibly sent bad data in next few minuts. In aria2, one piece is downloaded from several peers, so when hash check failed for that piece, it cannot determine which peer(s) sent bad data. So, we ignore peer who sent last block of data in random minutes. We use randomized timeout because all peers get waken up at the almost same time.
Added suggestion for unknown/ambiguous options. The help messages shown when argument error were redesigned and less verbose now. When unknown or ambiguous option is given, show suggestions like "Did you mean...". Some constant values related to levenstein distance are borrowed from git help.c.
Added --stop-with-process=PID option. This feature stops application when process PID is not running. This is useful if aria2 process is forked from a parent process. The parent process can fork aria2 with its own pid and when parent process exits for some reason, aria2 can detect it and shutdown itself. The code which detects whether or not given process PID is running is contributed by Emmanuel Engelhart.
Support IPv6 address for FTP via HTTP tunneling.
The previous implementation could not handle the situation when user, password and proxy URI is given various order. Now we just set rules: username set in --*-proxy-user overrides username in --*-proxy option, no matter in any order username, password and proxy URI are parsed. Likewise, password set in --*--proxy-passwd overrides password in --*-proxy option.
Changed format of ETA. Now no leading 0 is used. If hour part and/or min part is non-zero, and sec part is 0, sec part is omitted, like this "1h3m".
Rewritten Metalink XML parser. Now we don't strip white spaces while parsing Metalink V3 document.
Now xml attribute and characters in RPC request is not stripped at all.
Fixed bug that some information such as port number is lost if redirect URI contains only path component.
Apply PREF_MAX_CONNECTION_PER_SERVER to BitTorrent WEB Seeding hosts.
Reuse in-flight and pooled URIs when a download is paused.
Deprecated --metalink-server option. Use --split option instead.
Made max value of --select-file to 65535
Use same domain-match algorithm for no-proxy and netrc. Now "example.org" does not domain-match ".example.org" in both functions.
For waiting or paused downloads, the options listed in Input File subsection in man page are available in aria2.changeOption RPC method, except for following options: dry-run, metalink-base-uri, parameterized-uri, pause and piece_length.
Made --download-result, --save-session, --server-stat-of and --save-cookies option available in aria2.changeGlobalOption. In addition to them, the options listed in Input File subsection in man page are also available, except for following options: checksum, index-out, out, pause and select-file.
Made --uri-selector option available in -i list.
Support IPv6 literal address in proxy option.
Support IPv6 CIDR block in --http-no-proxy option.
HttpProxyOptionHandler: Enclose hostname with square brackets if hostname is IPv6 numeric address.

New in aria2 1.13.0 (Oct 10, 2011)

Check libgcrypt version is greater or equal to required version. This will fixes Debian bug#642989.
Added --piece-length option. This option sets a piece length for HTTP/FTP downloads. This is the boundary when aria2 splits a file. All splits occur at multiple of this length. This option will be ignored in BitTorrent downloads. It will be also ignored if Metalink file contains piece hashes.
Throw exception if parameter has wrong type in RPC method. Formally, depending on the method implementation, this kind of error is just ignored and parameter is skipped. Now aria2 responds error for these cases. The required parameter checking is also reworked along with this change.
Cleanup log message for binding server socket.
Recognize tab as white space before option in -i list.
Added geom parameter to --stream-piece-selector option. If 'geom' is given, at the beginning aria2 selects piece which has minimum index like 'inorder', but it exponentially increasingly keeps space from previously selected piece. This will reduce the number of establishing connection and at the same time it will download the beginning part of the file first. This will be useful to view movie while downloading it.
Added completedLength response key in aria2.getFiles RPC method
Added #checksum help tag.
Added --checksum option. Added --checksum=TYPE=DIGEST option. This
option sets checksum. TYPE is hash type. The supported hash type is
listed in "Hash Algorithms" in "aria2c -v". DIGEST is hex digest.
For example, setting sha-1 digest looks like this:
sha-1=0192ba11326fe2298c8cb4de616f4d4140213838 This option applies
only to HTTP(S)/FTP downloads.
Added --hash-check-only opiton. Added --hash-check-only option. If true is given, after hash check using --check-integrity option, abort download whether or not download is complete. The default value is false.
Added --download-result option. Added --download-result=OPT option. This option changes the way "Download Results" is formatted. If OPT is 'default', print GID, status, average download speed and path/URI. If multiple files are involve , path/URI of first requested file is printed and remaining ones are omitted. If OPT is 'full', print GID, status, average download speed, percentage of progress and path/URI. The percentage of progress and path/URI are printed for each requested file in each row.
Added --rpc-allow-origin-all option. This option adds Access-Control-Allow-Origin header field with value '*' to the RPC
response.
Ignore --out option supplied in command-line if -i is used. You can still use out option in the text file specified in -i.
Disable SSLv2 by default and optimize memory usage. Patch from Cristian Rodr√≠guez.
Added libnettle and libgmp support. libnettle and libgmp is usedby default. Old implementation uses libgcrypt as default. If more and more Linux distributions offer libnettle linked GnuTLS, then this change decrease library dependency against libgcrypt and libgpg-error. The current library detection for libnettle and libgmp is very simple, just use AC_SEARCH_LIBS. util::generateRandomData() was written using SimpleRandomizer, thus no external library dependency from this function.
In MinGW32, open file with UNICODE filename and print them in ANSI.

Updated gettext to 0.18
Added JSON-RPC support. --enable-xml-rpc was deprecated and --enable-rpc should be used instead. Similarly, --xml-rpc-* options were replaced with --rpc-* options. We are implementing JSON-RPC based on JSON-RPC 2.0 draft spec.
Fixed rounding error in DownloadEngine::run(). This fixes the bug that executeCommand() with Command::STATUS_ALL is not called in every interval correctly because of rounding error in timer.
Refresh buckets at DHT initialization without checking serialized time. Checking serialized time does not work if you stop aria2 as soon as it started DHT. The serialized time in dht.dat will be updated, but buckets are not updated and still old. When you restart aria2 again soon, it does not refresh buckets because serialized time is recent.
Save downloads added by aria2.addTorrent or aria2.addMetalink in --save-session file. Uploaded data are saved as file named hex string of sha1 hash of uploaded data plus extension(".torrent" for torrent and ".meta4" for metalink). For example, 0a3893293e27ac0490424c06de4d09242215f0a6.torrent. The directory where these files are saved is specified by --dir option. These file paths are written in --save-session file.
Fixed the bug that causes segmentation fault when unpause RequestGroup which has resolved BtDependency.
Look for USERPROFILE and the combination of HOMEDRIVE and HOMEPATH to get user's home directory in MinGW32 build. Usually HOME environment variable is defined in *nix like OSes, but not in Windows. So in MinGW32 build, if HOME is not defined, we also look for USERPROFILE and the combination of HOMEDRIVE and HOMEPATH.
Fixed the bug that DownloadContext::basePath_ is not escaped.
Added Date, Expires and Cache-Control response header field to RPC response.
Added --async-dns-server option. This option accepts comma separated list of DNS server addresses used in asynchronous DNS resolver. Usually asynchronous DNS resolver reads DNS server addresses from /etc/resolv.conf. When this option is used, it uses DNS servers specified in this option instead of ones in /etc/resolv.conf. You can specify both IPv4 and IPv6 address. This option is useful when the system does not have /etc/resolv.conf and user does not have the permission to create it.
Accept https:// and ftp:// in proxy options and environment variables.
Fixed overflow in the calculation of progress percentage for file allocation and hash check when off_t is 32bit.
Accept HTTP 304 reply as success when If-None-Match request-header field is specified using --header option. When --conditional-get is used, --allow-overwrite is now required to overwrite existing file.
Added aria2.removeDownloadResult RPC method. The method signature is aria2.removeDownloadResult(gid). This method removes completed/error/removed download denoted by gid from memory. This method returns "OK" for success.
Use IP address of control connection to connect to the remote server in FTP passive mode.
Don't check permission of .netrc file in MinGW32 build.
Added --retry-wait option. This option was once existed in aria2 but erased on 2009-09-20. Now it is resurrected once again. We choose 0 as default value for backward compatibility. Now we retry HTTP download when remote server returns "503 Service Unavailable" if --retry-wait > 0. We also added error code 29: HTTP_SERVICE_UNAVAILABLE.
Don't show metadata download and paused download in "Download Results".

Updated Russian, Simplified Chinese and French translation. Thanks to all translators.
Use RFC1123 date format for creation date of .torrent file printed using -S.
Rewritten Cookie class and Cookie parser based on http://tools.ietf.org/html/draft-ietf-httpstate-cookie-15 Use inet_ntoa if inet_ntop is not available. Since inet_ntoa does not handle IPv6 address, IPv6 support is limited in this case. Fixed unit test error under mingw32.
Don't show warning message in console when CA certificates are not imported.--ca-certificate and --check-certificate option were mentioned in the error message displayed when certificate verification failed.
Print message when performing slow file allocation at first time.
Fixed compile error on OpenBSD4.7(i386).
Execute 5 DHT tasks concurrently in each task queue.
Fixed the bug that FtpFinishDownloadCommand does not handle timeout. This means it waits for the remote server to send "226 Transfer Complete" message *without* its own timeout until the remote server shutdowns connection(we can detect EOF in this case).
Rewritten util::escapePath(). Now it does not replace bad chars with '_':it performs percent-encoding against them.
util::fixTaintedBasename() now replaces "/" with "/".Added 0x7f as bad chars in util::detectDirTraversal().
Non-UTF8 filenames are now percent-encoded. The comments and name in .torrent file in XML-RPC response are percent-encoded if they are not UTF-8. Reset download start time of PeerStat because it is started before file allocation begins.
Without reset, we have incorrect download time and aria2 wrongly determines that download speed is too low if --lowest-speed-limit is used.
Added keys parameter to aria2.tellStatus, aria2.tellActive, aria2.tellWaiting and aria2.tellStopped XML-RPC method.'keys' is array of string. If it is specified, the response contains only keys in 'keys' array. If 'keys' is empty or not specified, the
response contains all keys.This is useful when you just want specific keys and avoid unnecessary transfers. For example, aria2.tellStatus("1", ["gid", "status"]) returns 'gid' and 'status' key.

Set max outstanding request size of BitTorrent download to 100. Setstepping to 6.
Added --bt-tracker and --bt-exclude-tracker option. In--bt-tracker option, you can specify comma separated list ofadditional BitTorrent tracker's announce URI. These URIs are notaffected by --bt-exclude-tracker option because they are addedafter URIs in --bt-exclude-tracker option are removed. In--bt-exclude-tracker option, you can specify comma separated listof BitTorrent tracker's announce URI to remove. You can use specialvalue '*' which matches all URIs, thus removes all announceURIs. When specifying '*' in shell command-line, don't forget toescape or quote it. Added bt-tracker and bt-exclude-tracker to -ilist option.
Listen both IPv4 and IPv6 for BitTorrent protocol.
Listen both IPv4 and IPv6 for xml-rpc request.
Added IPv6 DHT. Added --dht-entry-porint6, --dht-file-path6,--dht-listen-addr6 and --enable-dht6 option. IPv6 DHT is disabledby default. To use IPv6 DHT, you need to use --enable-dht6 andspecify a global unicast address to --dht-listen-addr6. IPv6 DHTis highly experimental.
Added support for peers6 key in tracker response. Added added6,added6.f and dropped6 in ut_pex.
Add only gracefully disconnected peer to ut_pex dropped list. Addincoming dropped list to PeerStorage.
Don't use pre-calculate hash value when end-game mode. Throwexception if bad piece is received.
Added bittorrent::packcompact() which replacesbittorrent::createcompact() and supports IPv6 addresses. Rewrittenbittorrent::unpackcompact() and bittorrent::extractPeer() tosupport IPv6 addresses. Fixed added.f flags in ut_pex.
Added --enable-async-dns6 option. This option enables IPv6 nameresolution in asynchronous DNS resolver. This option will beignored when --async-dns=false.
Use hostname of original URI when counting hostname ininFlightRequest.
Fixed the bug thatAdaptiveFileAllocationIterator::getCurrentLength() does not returnupdated allocated bytes.
Added FTP EPSV and EPRT command support. aria2 issues thesecommands when address family of local socket is AF_INET6.
Rewritten check for fallocate using AC_COMPILE_IFELSE.
Fixed the bug that HAVE_SOME_FALLOCATE gets undefined if fallocateis not available even if posix_fallocate is available. This causesFallocFileAllocationIterator.cc is out of compile targets andlinker error.

New in aria2 1.10.0 (Jul 19, 2010)

Metadata download may take very long time. If URIs are available, give up metadata download in at most 30 seconds.
Added --on-bt-download-complete=COMMAND option. For BitTorrent, a command specified in --on-download-complete is called when download completes and seeding is over. On the other hand, this option set the command to be executed when download completes but before seeding.
Added --conditional-get option. Download file only when the local file is older than remote file.
This function only works with HTTP(S) downloads only. It does not work if file size is specified in Metalink. It also ignores Content-Disposition header.
If a control file exists, this option will be ignored. This function uses If-Modified-Since header to get only newer file conditionally.
When getting modification time of local file, it uses user supplied filename(see --out option) or filename part in URI if --out is not specified.
FeedbackURISelector now tries to select URI whose host is least used in aria2 globally.
Added --min-split-size=SIZE option. aria2 does not split less than 2*SIZE byte range. For example, let's consider downloading 20MiB file.
If SIZE is 10M, aria2 can split file into 2 range [0-10MiB) and [10MiB-20MiB) and download it using 2 sources(if --split >= 2, of course). If SIZE is 15M, since 2*15M > 20MiB, aria2 does not split file and download it using 1 source.
Added --max-connection-per-server=NUM option. The default value of NUM is 1. This option limits the number of connections allowed to one server for each download. This means when NUM is 2 and 1 URI is provided, even if you specified -s 5, aria2 establishes 2 connections.
Set end byte in Range header if start byte > 0 to get more chance to pool socket.
Fixed ChunkedDecoder. It does not read trailer and final CRLF. Send each CWD component of FTP URI in separate CWD command as described in RFC1738.
Fixed the bug that aria2 cannot handle / in FTP URI properly. If directory component starts with / which percent-encode of '/', client should issue CWD to absolute path, but aria2 does not do that. It just issues relative path and download fails.
Added Chromium/Google Chrome Cookies file support. Thanks to gotrunks for original patch.
When allocating disk space, for Linux system with fallocate() system call, first check file system supports fallocate.
This just run fallocate with small chunk and see it succeeds or fails. If it succeeds, use fallocate() to allocate entire file otherwise fall
back to traditional slower method: writing zeros.
This behavior is enabled in --file-allocation=prealloc, so this is enabled by default for most modern Linux.

Updated Ukrainian, Russian, Simplified Chinese, German and Greek translation. Thanks to all translators.
Added warning for the system which lacks clock_gettime with CLOCK_MONOTONIC.
Fixed the bug that hash check hangs when aria2.pause is issued while aria2 is checking piece hashes. Fixed the bug that the download is paused after file allocation completion even if aria2.pause is issued during file allocation.
Fixed compile error on opensolaris
Added aria2.forcePause, aria2.pauseAll, aria2.forcePauseAll and aria2.unpauseAll XML-RPC method.
Use clock_gettime(CLOCK_MONOTONIC, ...) if it is available and usable to prevent from aria2 from being affected by system time change.
Added aria2.pause and aria2.unpause XML-RPC method. aria2.pause pauses the download denoted by gid. gid is of type string. The status of paused download becomes "paused" and the download is placed on the first position of waiting queue. As long as the status is "paused", the download is not started. To change status to "waiting", use aria2.unpause method. This method returns GID of paused download. aria2.unpause changes the status of the download denoted by gid from "paused" to "waiting". This makes the download eligible to restart. gid is of type string. This method returns GID of unpaused download.
Added --save-session=FILE option. This option saves error/unfinished downloads to FILE on exit. You can pass this output file to aria2c with -i option on restart. Please note that downloads added by aria2.addTorrent and aria2.addMetalink XML-RPC method are not saved.
Fixed the bug that FTP data connection is not established via proxy when --ftp-proxy is defined and --ftp-pasv=true and --proxy-method=tunnel.
Fixed the bug that web-seed URI is not percent-encoded.
Added aria2.shutdown and aria2.forceShutdown XML-RPC method. These methods, as their name imply, shutdown aria2. These methods are useful for Windows because it lacks signal mechanism.
Don't send "Accept-Encoding: default, gzip" by default. This is because some servers respond with "Content-Encoding: gzip" for a file which itself is gzipped file and aria2 inflates them. This is a problem if user doesn't want to inflate the file. Apparently this is server configuration error, but we cannot do anything about this. So we turned this off. Added --http-accept-gzip option. If true is given to this option, aria2 sends "Accept-Encoding: deflate, gzip" request header and inflates response if remote server responds with "Content-Encoding: gzip" or "Content-Encoding: deflate". We removed extension "tgz" hack in order not to inflate files with tgz extensions.
Made aria2 not send "application/metalink4+xml,application/metalink+xml" in Accept header for web-seeding URIs and tracker request.
Added --dht-message-timeout option.
Added --bt-tracker-connect-timeout and --bt-tracker-timeout option.
Documented that specifying --seed-time=0 disables seeding after download completed.
Drop connection if same Peer ID has been already seen.
Fixed the bug that waiting download unintentionally starts when URIs are added to it using aria2.changeUri XML-RPC method.
Fixed compile error with g++-4.4 on FreeBSD.
Fixed the bug that URIs added using aria2.changeUri XML-RPC method are not used immediately if there is no URI remaining before calling aria2.changeUri and the number of connection is less than the value in -s(or -C for Metalink downloads).
Added --always-resume and --max-resume-failure-tries option. If --always-resume=false is given, when all given URIs do not support resume or aria2 encounters N URIs which does not support resume (N is the value specified using --max-resume-failure-tries option), aria2 downloads file from scratch. The default behavior is --always-resume=true, which means if all URIs do not support resume, download fails. I think this is OK because user normally doesn't like to see that partially downloaded file is overwritten(this is particularly true if file size is big). This option is useful when aria2 is used as a download backend and graceful falling back to overwritten behavior is preferable. Added exit status value 8, which means download failed because server did not support resume.
Added --remove-control-file option. This option removes control file(*.aria2 file) before download. Using with --allow-overwrite=true, download always starts from scratch. This will be useful for users behind proxy server which disables resume. For such proxy user, -C1 is also recommended for Metalink downloads to avoid establishing unnecessary connections.
Added v key in DHT message. aria2's DHT version is independent of the package version and we defined it as 1 at the moment. It is defined as DHT_VERSION in src/DHTConstants.h. aria2's DHT version scheme is "A2"+2bytes DHT version number in network byte order.
Fixed the bug that value of numSeeders in aria2.tellStatus XML-RPC method response is integer, while it should be string. The man page says it is string. When peer's port is not listening port, set '0' to port in aria2.getPeers response.
Lines starting "#" in -i list are treated as comments.
Accept IPv4 network address with CIDR block in --no-proxy option and no_proxy environment variable. Current implementation does not resolve hostname in URI to compare network address. So it is only effecive if URI has numeric IP address.

aria2 now returns gzip compressed XML-RPC response if XML-RPC client accepts gzip content encoding.
Added dir and files key to the response struct of aria2.tellStatus XML-RPC method. The value associated with files key is the list of files. Its element is the same struct used in aria2.getFiles XML-RPC method. Added uris key to the response struct of aria2.getFiles XML-RPC method. The value associated with uris key is the list of URIs. Its element is the same struct used in aria2.getUris XML-RPC method.
Added aria2.getSessionInfo XML-RPC method. This method returns a struct containing Session ID, which is generated each time when aria2 is invoked.
Now offset argument in aria2.tellWaiting and aria2.tellStopped accept a negative integer. 'offset' == -1 points last download in the waiting queue and 'offset' == -2 points the download before the last download, and so on. The downloads in the response are in reversed order.
Added --human-readable option. This option, when true is given, prints sizes and speed in human readable format(e.g., 1.2Ki, 3.4Mi) in the console readout. The default value is true and it looks exactly the same as aria2-1.8.0. So the 'new feature' appears when false is given. In this case, sizes and speed are printed in bytes. No Ki, Mi units conversion is used. This may be useful for a program to parse the output of aria2.
Now --all-proxy, --http-proxy, --https-proxy and --ftp-proxy option accept empty string "". When "" is given, it erases previously defined proxy.
Added --bt-metadata-only option. If true is given to this option, aria2 downloads metadata only. The file(s) described in metadata will not be downloaded. This option has effect only when BitTorrent Magnet URI is used. See also --bt-save-metadata option.
Fixed memory leak. Commands stored in std::deque are not deleted when exception is thrown.
Replaced '/' and '' with '_' in HTTP/FTP filename.
Treat --dir="" as --dir="."
Added --http-no-cache option. When true is given, aria2 sends Cache-Control: no-cache and Pragma: no-cache header to avoid cached content. If false is given , these headers are not sent and you can add Cache-Control header with a directive you like using --header option.
Added following sentence to the help message of --out option: --out option is ignored when -Z is used.
Added --bt-save-metadata option to -i list options.
Fixed compile error with i586-mingw32msvc-gcc 4.4.2, which is debian's corss compiler, without any additional libraries.
Fixed the bug that causes segmentation fault if unknown option is put in aria2.conf file. BUG#2928303
Ignore port message with port=0.
Updated autoconf/automake auxiliary files.

New in aria2 1.8.0 (Dec 28, 2009)

Added signal handler for SIGHUP to save .aria2 file when terminal is closed. The handler is the same one for SIGINT and SIGTERM.
Added system.multicall XML-RPC method.
Added tellStopped XML-RPC method. This method returns stopped download in the specified range. It takes same parameters with tellWaiting XML-RPC method. offset = 0 means the oldest download.
Use AI_ADDRCONFIG flag if it is available. Refactored so that getaddrinfo calls are not scattered around. Unset AI_ADDRCONFIG when conducting unit tests because they fail if networking interface is not configured with IPv4 address.
Added --bt-save-metadata option. When true is given, it saves metadata as .torrent file. This option has effect only when BitTorrent Magnet URI is used. The filename is hex encoded info hash with suffix .torrent. The directory to be saved is the same directory where download file is saved. If the same file already exists, metdata is not saved.
Added changePosition XML-RPC method. It takes 3 parameters: gid, pos and how. This method changes the position of download denoted by gid. If how is POS_SET, it moves the download to a position relative to the beginning of the queue. If how is POS_CUR, it moves the download to a position relative to the current position. If how is POS_END, it moves the download to a position relative to the end of the queue. If the destination position is less than 0 or beyond the end of the queue, it moves the download to the beginning or the end of the queue respectively. Returns the destination position.
Added getOption and getGlobalOption XML-RPC method. getOption takes GID as a parameter and returns its options as struct. getGlobalOption takes no parameter and returns global options. Because global option is used as a template for the option of newly added downloads, it includes options returned by getOption.
Added following 2 keys, followedBy and belongsTo, to the response of tellStatus.
Show info hash in Magnet URI in upper case letters in -S output.
Fixed the bug that if --without-sqlite3 is given, pkg-config is not properly used in configure script and failed to detect gnutls. This is because explicit call of PKG_PROG_PKG_CONFIG is missing and the initialization of pkg-config is done in first occurrence of PKG_CHECK_MODULES which is not executed because it is inside of sqlite3.m4. Added explicit PKG_PROG_PKG_CONFIG call.

Fixed the segmentation fault during execution of choking algorithm in leecher state because of broken compare operator implementation.
Open file in binary mode. This fixes the bug that local torrent file doesn't work on win32.
Added a check to see struct sockaddr_in has sin_len member. Set struct sockaddr_in.sin_len if HAVE_SOCKADDR_IN_SIN_LEN is defined.
Fixed possible buffer overrun when writing dht.dat.
Fix epoll error on the old kernel 2.6.8 or ealier.
Fixed the bug that adding 0 length filter to BitfieldMan filters 1 block. It should not filter anything.
Fixed broken selected file BitTorrent download.
Changed the default value of --proxy-method option from 'tunnel' to 'get'. Use 'tunnel' for HTTPS regardless of --proxy-method option.
Added --bt-external-ip option. You can specify the external IP address to report to a BitTorrent tracker. Although this function is named 'external', it can accept any kind of IP addresses.
Applied AdaptiveURISelector-timeout patch from Pascal Rigaux at Mandriva. I modified the patch: make RequestGroup have the timeout value and AdaptiveURISelector directly modifies that value.
Use LongestSequencePieceSelector for HTTP/FTP/BitTorrent integrated downloads. This PieceSelector subclass finds the longest continuous sequence in the available missing pieces and selects the last index of such sequence. This makes HTTP/FTP connections less interrupted by the pieces obtained by BitTorrent peers.
Fixed the bug that the average speed is wrong in http/ftp/BitTorrent integrated download. Only the download bytes in BitTorrent were considered.
Choose port for BitTorrent/DHT randomly from the specified range. REQUEST#2543518
Send HTTP Authorization header only if it is requested by the server(response 401). There are some exceptions. The authorization header for proxy is always sent if it is available without request by the server. If username/password is specified in the URI, it is immediately sent to the server without request by the server. Implements REQUEST#2540844.
Remove leading "--" from help keyword and a substring after "=" from help keyword, so that one can query options by '-h--max-' or '-hmax-peers=10'.
Added experimental built-in HTTP server. Currently, when a client accesses to the server, it responds with the current download progress. By default, it is disabled. To enable the server, give --enable-http-server option. To change the default port number for the server to listen to, use --http-server-listen-port option. The response HTML is very simple and refreshes it self each 1 second. Because of this refresh, you see flicker in normal web browser such as Firefox. I recommend to use console-based browser such as elinks, w3m. To connect to the server, run 'elinks http://localhost:6800/' while running aria2. Please replace port number '6800'(which is default) with your preference.
Made (piece) hash check sequential for each RequestGroup because simultaneous hash check is slower than sequential execution.
Added --bt-max-peers option to specify the maximum number of peers per torrent. 0 means unlimited number of peers. REQUEST#2451382
Added --bt-hash-check-seed option. If true is given to this option, after hash check using --check-integrity option and file is complete, continue to seed file. If you want to check file and download it only when it is damaged or incomplete, set this option to false. This option has effect only on BitTorrent download. The default value is true(This is the same behavior with the previous release).
Made the max value of split option unlimited. REQUEST#2496748
Added --event-poll option to select the method for polling events. The available methods are "select" and "epoll". "epoll" is available on Linux only. The earlier release has the compile option to choose from these methods.
Included RecoverableException.h from main.cc. BUG#2498160
Applied exit-status patch from Pascal Rigaux at Mandriva. aria2 now returns last error encountered in the HTTP/FTP downloads as a exit status value. If all downloads finished successfully, aria2 returns 0. The error code is defined in src/DownloadResult.h. The error occurred in the download currently in progress is not reported as a last error. If no error has encountered but there are in progress or waiting downloads, aria2 returns 7.
Applied AdaptiveURISelector patch from Aurelien Lefebvre. This patch adds AdaptiveURISelector, which selects one of the bests mirrors for first and reserved connections. For supplementary ones, it returns mirrors which has not been tested yet, and if each of them already tested, returns mirrors which has to be tested again. Otherwise, it doesn't return anymore mirrors.
Fixed unit test error in HTTPResponseTest. PATCH#2485509

Print the contents of torrent/metalink files without -T/-M options.
Updated French, Japanese, Russian and Ukrainian translations. Thanks to all translators.
Rename file by appending digits if a local file exists and its file size is larger than that of remote file with --continue option. The old implementation just throws exception in such case.
Fixed the bug that download progress summary is not printed in the interval specified by the option.
Fixed the cookie implementation based on RFC2965. Now if a value in domain field is not started with dot, then prepend dot. That means a cookie with domain=sf.net is sent to wiki.sf.net.
Fixed the bug that causes corrupted downloads if HTTP pipelining is enabled and the server doesn't support keep-alive.
Added --max-overall-upload-limit option. This option limits the overall upload speed. Stated in help message that the existing --max-upload-limit option limits the upload speed per each torrent. Man page is also updated.
Fixed the bug that bad URI is sent to the tracker when the announe URI in torrent file includes query.
Enabled --check-certificate by default. Added compile time(configure) option --with-ca-bundle to specify CA bundle. Warn if --check-certificate=true and --ca-certificate is not specified or loading CA certificate is failed.
Added "https" tag to help option category. Added https tag to --ca-certificate, --certificate, --check-certificate and --private-key option.
Changed the package name from "aria2c" to "aria2". The name of the executable is not changed. This change was done in order to fix the inconsistency of the package name and the install directory since in many distributions the binary package name is "aria2", but the old releases tried to install to "aria2c" directory such as "/usr/local/share/doc/aria2c".
Fixed typos in man page.
RFC3986 complied Percent-Encoding(urlencode). Use uppercase hexadecimal digits for encoded text instead of lowercase ones.
Fixed the bug that -pfalse and -ptrue are not recognized properly.
Fixed the bug that prevents aria2 from downloading 0-length files via HTTP/FTP.

Added deliminating text to the beginning of the log so that one can find where the log starts easily.
Use non-blocking socket for TCP communication to avoid possible blocking due to buffer full.
Added --max-file-not-found=NUM option. If aria2 receives `file not found' error from HTTP/FTP server NUM times without getting single bytes of data, then force the download to fail.
Use pkg-config for sqlite3, openssl.
Added --connect-timeout option to specify connect timeout in seconds. This option is in effect for HTTP/FTP/proxy server. The timeout for connecting to BitTorrent peer is not controlled by this option.
Implemented the ability to get timestamp from remote HTTP/FTP server and apply it to local file. To enable this feature, --remote-time option.
If an error occurred with a URI, remove identical URI from remaining URI list because it is likely that same error occurred in the end and it is waste of time.
Contact tracker frequently when the number of connections are 0 and download is not finished yet.
Rewritten Cookie handling routine.
Bump up version number of dht.dat file to 3. In version 3 format, time is stored in 64bit, network byte order. New build can load old format(version 2) but it saves the file in new format. It means once you used new build, your dht.dat becomes incompatible with older build.
Bump up version number of .aria2 control file to 0001. New aria2 can still load version 0000 file but it saves the file in version 0001 format. It means that new aria2 can resume download started by old aria2 but the opposite is not true.
Added Firefox3 cookie support based on the patch submitted by tizianomueller. Firefox3 cookie is SQLite3 database. libsqlite3 is required to enable this functionality.
Implemented download speed based URI selection algorithm. Introduced new option --uri-selector. If --uri-selector=feedback is given, aria2 uses download speed observed in the previous downloads and chooses fastest server in the URI list. Currently at most 10 URIs are considered to introduce randomeness for finding better servers. The speed is average download speed in the downloads. On the other hand, if --uri-selector=inorder is given, which is default, URI is tried in order in URI list. Added options to load/save above information(download speed, status etc.) to a file: --server-stat-of, --server-stat-if. --server-stat-timeout is also added to control the life span of the saved data.
Integrated HelpItem into OptionParser to ease the workload for adding new options. Removed default value from usage text.
Issue PWD command first and get working directory and use it as a prefix for CWD command.
netrc are used for HTTP.
FTP user/password is sent in Authorization header when --ftp-via-http-proxy=get is given(non-transparent HTTP proxy).
Insert username+'@' to URI(after ftp://) when URI is FTP scheme and username is not in URI and non-transparent HTTP proxy is used.
Fixed the bug that prefixLength of split bucket which doesn't include local node ID is incremented.
Updated man page.
