New in Mercurial 6.1 (Jul 11, 2022)
- New Features:
- Added a way of specifying required extensions that prevent Mercurial from starting if they are not found. See hg help config.extensions.
- Merge conflict markers have been made clearer (see backwards compatibility below)
- Improve detailed error codes
- Added a hint about mangled whitespace on bad patch
- Explain which order the commits are presented in chistedit
- Introduce a dirstate-tracked-hint feature to help automation keep track of changes to tracked files. See hg help config.use-dirstate-tracked-hint.
- Shared repositories can be upgraded if the upgrade is specific to the share. For now, this only applies to dirstate-v2 and dirstate-tracked-hint.
- When using the narrow extension, non-conflicting changes to files outside of the narrow specification can now be merged.
- When cloning a repository using stream-clone, the client can now control the repository format variants to use as long as the stream content does not restrict that variant.
- Default Format Change:
- These changes affect newly created repositories (or new clones) done with Mercurial 6.1.
- The share-safe format variant is now enabled by default. It makes configuration and requirements more consistent across repository and their shares. This introduces a behavior change as shares from a repository using the new format will also use their main repository's configuration. See hg help config.format.use-share-safe for details about the feature and the available options for auto-upgrading existing shares.
- New Experimental Features:
- The pure Rust version of Mercurial called rhg added support for most common invocations of hg status. See hg help rust.rhg for details on how to try it out.
- rhg supports narrow clones and sparse checkouts.
- Bug Fixes:
- Obsolete revisions are skipped while computing heads. In conjunction with the evolve extension >= 10.5.0, this leads to massive exchange (push/pull) speedups in repositories with a lot of heads and/or obsolete revisions.
- Stream-clones now properly advertise all requirements needed. This can result in the stream-clone feature being disabled for some clients using < 6.0.2. A small bugfix patch for these older client is available if necessary.
- The --no-check and --no-merge flags now properly overwrite the behavior from commands.update.check
- rhg's fallback detection is more robust in general in the presence of more advanced configs
- rhg's blackbox now supports milliseconds by default and uses the same ISO 8601 format as the Python implementation
- Fix rhg crash on non-generaldelta revlogs
- The lfs, largefiles and sparse extensions now correctly take the appropriate lock before writing requirements
- The notify extension does not produce errors anymore if a revision is not found
- Remove unnecessary and overly strict check for divergence in hg fix
- Windows compatibility improvements
- Miscellaneous Python 3 and typing improvements
- Many other small or internal fixes
- Backwards Compatibility Changes:
- The use of share-safe, means shares (of new repositories) will also use their main repository's configuration see the Default Format Change section for details.
- The fix to stream-clone requirements advertising means some requirements previously (wronly) omitted are now sent. This can confuse client using a Mercurial version < 6.0.2. The client would consider these requirements unsupported even if it actually know them. If you encounter this, either upgrade your client or apply the necessary patch.
- The labels passed to merge tools have changed slightly. Merge tools can get labels passed to them if you include $labellocal, $labelbase, and/or $labelother in the merge-tool..args configuration. These labels used to have some space-padding, and truncation to fit within 72 columns. Both the padding and the truncation has been removed.
- Some of the text in labels passed to merge tools has changed. For example, in conflicts while running hg histedit, the labels used to be "local", "base", and "histedit". They are now "already edited", "parent of current change", and "current change", respectively.
- The computation of namedbranch heads now ignores obsolete revisions. User of the Changeset Evolution feature may see a change in location and numbers of heads of each named branches (and topic).
- The remotefilelog extension now requires an appropriate excludepattern for subrepositories.
- debugsparse's interface has been reworked to be more flexible. Since it's a debug command it is not actually a breaking change, but it is worth noting here.
- Temporary files for merges are now all inside a hgmerge directory instead of at the root of TMPDIR. The corresponding experimental mergetempdirprefix config option has been removed.
- Internal API Changes:
- The dirstate API received minor modifications.
- Miscellaneous:
- Removed exchange-v2. It was a prototype that had never been in a working state and had been left untouched since 2017.
New in Mercurial 6.0 (Feb 18, 2022)
- New Features:
- debugrebuildfncache now has an option to rebuild only the index files
- a new bookmarks.mode path option have been introduced to control the bookmark update strategy during exchange with a peer. See hg help config and look for section paths for details.
- the new bookmarks.mode paths option supports the new mode mirror. See hg help config and look for section paths for details.
- more commands support detailed exit codes when config ui.detailed-exit-codes is enabled
- Default Format Change:
- New Experimental Features:
- Major feature: version 2 of the dirstate is available (the first version is as old as Mercurial itself). It allows for much faster working copy inspection (status, diff, commit, update, etc.) and richer information (symlink and exec info on Windows, etc.). The format has been frozen with room for some future evolution and the current implementations (Python, Python + C, Python + Rust or pure Rust) should be compatible with any future change or optimization that the format allows. You can get more information in the internal documentation
- Added a new web.full-garbage-collection-rate to control performance. See
- de2e04fe4897a554b9ef433167f11ea4feb2e09c for more information
- Added a new histedit.later-commits-first option to affect the ordering of commits in chistedit to match the order in hg log -G. It will affect the text-based version before graduating from experimental.
- Bug Fixes:
- hg fix --working-dir now correctly works when in an uncommitted merge state
- Unintentional duplicated calls to hg fix's internals were removed, making it potentially much faster
- rhg cat can be called without a revision
- rhg cat can be called with the . revision
- rhg cat is more robust than before with regards to edge cases. Some still remain like a tag or bookmark that is ambiguous with a nodeid prefix, only nodeids (prefixed or not) are supported as of now.
- rhg cat is even faster
- rhg (Rust fast-path for hg) now supports the full config list syntax
- rhg now parses some corner-cases for revsets correctly
- Fixed an fsmonitor on Python 3 during exception handling
- Lots of Windows fixes
- Lots of miscellaneous other fixes
- Removed a CPython-specific compatibility hack to improve support for alternative Python implementations
- Added a compatibility fix for Python 3.11

- dirstateitem.new_added
- dirstateitem.new_from_p2
- dirstateitem.new_possibly_dirty
- dirstateitem.new_normal
- dirstateitem.from_p2_removed
- Miscellaneous:
- wireprotov1peer's batchable is now a simple function and not a generator
- anymore
- The Rust extensions (and by extension the experimental rhg status) only use a tree-based dirstate in-memory, even when using dirstate-v1. See bf8837e3d7cec40fe649c47163a3154dda03fa16 for more details
- The Rust minimum supported version is now 1.48.0 in accordance with out policy of keeping up with Debian stable
- The test harness plays nicer with the NixOS sandbox
- The test harness plays nicer with NetBSD
- Improved rpm packaging
New in Mercurial 5.9 (Sep 1, 2021)
- New Features:
- hg config now has a --source option to show where each configuration value comes from.
- Internal API Changes:
- The Dirstate API have been updated as the previous function leaked some internal details and did not distinct between two important cases: "We are changing parent and need to adjust the dirstate" and "some command is changing which file is tracked". To clarify the situation:
- the following functions have been deprecated:
- dirstate.add, - dirstate.normal, - dirstate.normallookup, - dirstate.merge, - dirstate.otherparent, - dirstate.remove, - dirstate.drop,
- these new functions are added for the "adjusting parents" use-case:
- dirstate.update_file, - dirstate.update_file_p1,
- these new function are added for the "adjusting wc file" use-case":
- dirstate.set_tracked, - dirstate.set_untracked, - dirstate.set_clean, - dirstate.set_possibly_dirty,
New in Mercurial 5.8 (May 7, 2021)
- Regularly scheduled feature release.
New in Mercurial 5.7.1 (May 7, 2021)
- Commands:

New in Mercurial 5.6 (Nov 15, 2020)
- New Features:
- hg mv -A can now be used with --at-rev. It behaves just like hg cp -A --at-rev, i.e. it marks the destination as a copy of the source whether or not the source still exists but the source must exist in the parent revision).
- New revset predicate diffcontains(pattern) for filtering revisions the same way as hg grep --diff pattern.
- The memory footprint per changeset and per file during pull/unbundle operations has been significantly reduced.
- Internal API Changes:
- merge.update() is now private (renamed to _update()). Hopefully the higher-level functions available in the same module cover your use cases.
- phases.registernew now takes a set of revisions instead of a list of nodes. phases.advanceboundary takes an optional set of revisions in addition to the list of nodes. The corresponeding members of the phasecache class follow this change.
- The addgroup member of revlog classes no longer keeps a list of all found nodes. It now returns True iff a node was found in the group. An optional callback for duplicated nodes can be used by callers to keep track of all nodes themselve.
- The _chaininfocache of revlog classes has been changed from a dict to a LRU cache.
New in Mercurial 5.5.2 (Oct 4, 2020)
- commands:

New in Mercurial 5.2 (Feb 4, 2020)
- Backwards Compatibility Changes:
- The infinitepush extension is believed to be unused, and will be deleted at the end of 2020 unless users contact [email protected].
- 'hg grep' now searches working copy file contents by default. We recognize this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior.
- API Changes:
- 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future.
- 'mercurial.hg.updatetotally' is now more thorough about checking its 'updatecheck' keyword argument. Previously invalid values would have used the configured default updatecheck method, but now will raise ValueError.
- 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.
- commands:
- amend: add option to update to the current user
- amend: enable support for closing the branch
- amend: enable support for using the secret phase
- bookmarks: actual fix for race condition deleting bookmark
- bookmarks: remove changectx() method from bmstore (API)
- branchmap: explicitly warm+write all subsets of the branchmap caches
- import: add debug messages when parsing data from patch header
- import: read X-Mercurial-Node email header to determine nodeid
- log: populate keywords if specified in custom -Tjson(...) or -Tcbor(...)
- merge: replace magic strings with NAMED_CONSTANTS (API)
- push: support config option to require revs be specified when running push
- core:
- exchange: abort on pushing bookmarks pointing to secret changesets (issue6159)
- exchange: avoid unnecessary conversion of bookmark nodes to hex (API)
- revlog: add a 'sidedata' parameters to addrevision
- revlog: add a way to control sidedata changes during revlog.clone
- revlog: add the appropriate flag is sidedata are passed to 'addrevision'
- revlog: assign rawtext earlier in '_revisiondata'
- revlog: avoid caching raw text too early in _revisiondata

New in Mercurial 5.0 (May 23, 2019)
- New Features:
- ui.relative-paths option for getting relative path output from most commands. This is enabled when ui.tweakdefaults is enabled.
- expectsize() revset errors out if revset has unexpected number of elements.
- config() template function for getting a config value.
- {negrev} template keyword shows the negative revision number. This is convenient because it is usually shorter than the positive number, but note that it is less stable.
- hg uncommit now has an --allow-dirty-working-copy option.
- hg shelve now has --keep option, which shelves but also leaves the working directory unchanged.
- hg diff will now include specified files in subrepos.
- hg recover now has a --no-verify option
- Python 3 Support (Beta):
- Mercurial 5.0 has beta level support for running on Python 3.5, 3.6, and 3.7. The Mercurial distribution itself and all extensions bundled with it should work on these Python versions.
- To use Mercurial with Python 3, invoke setup.py with a Python 3 interpreter or set the PYTHON variable to a Python 3 interpreter when invoking the Makefile. e.g. python3.7 setup.py install or make install-home PYTHON=python3.7.
- 3rd party extensions will likely need to be ported to support running on Python 3 and attempts to run many existing extensions with a Python 3 powered Mercurial will result in extension loading failures. See the Python3 page for more.
- While the Mercurial test suite has a >99% pass rate when running with Python 3.5, 3.6, and 3.7, we anticipate that there are still many Python 3 bugs lingering in Mercurial. Please report Python 3 issues using the instructions at BugTracker.
- If you package Mercurial or distribute it to users, we do not recommend making Python 3 the default at this time.
- Python 3 is not yet very well tested on Windows and there are likely several more lingering issues on Windows compared to Linux, macOS, and other UNIX-like platforms.
- Other Improvements:
- Improved color scheme for histedit's curses interface, making it more consistent with the curses hunk selector.
- Bug Fixes:
- Histedit's curse interface has improved support for non ascii characters.
- Backwards Compatibility Changes:
- color: change color of grep.rev label (BC)
- commit: if interactive, look elsewhere for whitespace settings (BC)
- diff: make sure we output stat even when --git is not passed (issue4037) (BC)
- uncommit: abort if an explicitly given file cannot be uncommitted (BC)
- The Windows Inno installers no longer ship the pywin32 package. This package was being bundled for historical reasons. Mercurial stopped using pywin32 several years ago and the disappearance of this package should not have any meaningful impact.
- The 32-bit Windows Inno installers no longer distribute w9xpopen.exe. This should only impact people running Mercurial on Windows 95, 98, or ME.
- The Windows MSI installers no longer include the Python sphinx package and its various dependencies.
- The Windows MSI installers no longer include the pywin32 Python package.
- The Windows MSI installers no longer include the enum and future Python packages.

- lazymanifest: don't crash when out of memory (issue5916)
New in Mercurial 4.6.1 (Jun 7, 2018)
- This release is a security release due to multiple issues found in mpatch.c with a fuzzer. No exploits are known at the time, however, it is highly recommended that all users upgrade.
- Also included in this release are the following:
- zstandard: pull in bug fixes from upstream 0.9.1 (issue5884)
- bundle2: fix old clients from reading newer format (issue5872)
- bdiff: fix xdiff long/int64 conversion (issue5885)

- revset: pass in lookup function to matchany() (issue5879)
New in Mercurial 4.6 (May 14, 2018)
- NEW FEATURES:
- pullbundles:
- Pullbundles allow the server to answer client requests using pre-built bundles.
- push:
- If 'server.streamunbundle' option is enabled, the server will directly apply the changes send by the changes. This avoids potentially large temporary files on the server side. It can also prevent concurrent pushes.
- Notify extension:
- The 'maxdiffstat' option can be used to truncate long file lists similar to 'maxdiff' for the patch part of the email.
- hgweb:
- hgweb now shows date and user for operations that resulted in obsolete commit(s). For unstable commits, it shows the exact reason why they are considered unstable.
- Server: header is now configurable using web.server-header option.
- Templates:
- A new template keyword 'reporoot' which shows the root directory of the current repository. A new template function 'mailmap' which maps author fields based on values in a .mailmap file.
- Other notable features:
- revset: parse error now shows a hint where the error occurred
- templates: parse error now shows a hint where the error occured
- forget: new '--dry-run' and '--interactive' flags
- copyfile: preserve stat info (mtime, etc.) when doing copies/renames
- bundle2 format is documented and can be found using 'hg help internals.bundle2'
- BACKWARDS COMPATIBILITY CHANGES:
- Support for connecting to Mercurial servers older than 0.9.1 has been removed.
- Working-directory commands now respect "-X PATTERN" no matter if PATTERN matches explicitly-specified FILEs. For example, "hg add foo -X foo" no longer add the file "foo".
- Support for the experimental manifestv2 format has been removed, as it was never completed and failed to meet expectations.
- '{' in output filename passed to archive/cat/export is taken as a start of a template expression.
- The HTTP wire protocol server no longer accepts the "cmd" argument to control which command to run via HTTP POST bodies. The "cmd" argument must be specified on the URL query string.
- Hgweb no longer reads form data in POST requests from multipart/form-data and application/x-www-form-urlencoded requests. Arguments should be specified as URL path components or in the query string in the URL instead.
- Query string shorts in hgweb like "?cs=@" have been removed. Use URLs of the form "/:cmd" instead.
- The HTTP client no longer accepts text/plain and application/hg-changegroup Content-Type values as a valid Mercurial command response. These should only be encountered on pre 1.0 Mercurial servers.
- PERFORMANCE IMPROVEMENTS:
- 'hg manifest --all' is likely slower due to changing its implementation to respect storage interface boundaries. If you are impacted by this regression in a meaningful way, please make noise on the development mailing list and it can be dealt with.
- 'hg diff' is much faster for larger repositories. 40% improvements have been reported. Other operations using diffs like hgweb also benefit.
- BUG FIXES:
- grep: fixes erroneous output of grep in forward order (issue3885)
- dirstate: drop explicit files that shouldn't match (BC) (issue4679)
- procutil: rewrite popen() as a subprocess.Popen wrapper (issue4746) (API)

- NEW EXPERIMENTAL FEATURES:
- Each release there are lot of new features added which are hidden under the EXPERIMENTAL tag as the behavior may change in future or the feature is not complete yet. The experimental features added in this cycle are:
- narrow extension:
- Allows to create clones which fetch history data for only a subset of files. This experimental extension is now distributed with Mercurial.
- remotenames extension:
- Shows remotebookmarks and remotebranches in the UI. This experimental extension is now distributed with Mercurial.
- infinitepush extension:
- Allows to store some pushes in a remote blob store on the server and to serve commits from remote blob store. The revisions are stored on disk or in everstore, the metadata are stored in sql or on disk. This experimental extension is now distributed with Mercurial.
- Fix extension:
- Allows to rewrite file content in changesets or working copy. For example, automatically applying formatting fixes to modified lines of code. This experimental extension is now distributed with Mercurial.
- API CHANGES:
- Content from mercurial.hgweb.protocol has been moved to mercurial.wireprotoserver.
- Content from mercurial.sshserver has been moved into mercurial.wireprotoserver.
- The following deprecated methods have been removed from obsutil: marker.precnode() and allprecursors(). Use marker.prednode() and allpredecessors() instead.
- beginparentchange() and endparentchange() have been replaced by the parentchange context manager.
- The deprecated localrepo.walk() has been removed, and replaced by repo[node].walk().
- The following deprecated methods have been removed from bookmarks: __setitem__(), __delitem__(), update(), and recordchange(). Use bookmarks.applychanges() instead.
- The cmdutil._revertprefetch() hook point for prefetching stored files has been replaced by the command agnostic cmdutil._prefetchfiles(). The new function takes a list of files, instead of a list of lists of files.
- sshpeer.sshpeer.__init__ now receives arguments describing an existing connection instead of creating a connection itself.
- sshpeer.sshpeer renamed to sshpeer.sshv1peer.
- wireproto.pushres and wireproto.pusherr now explicitly track stdio output.
- redirect() and restore() have been removed from the wire protocol handler interface. Use mayberedirectstdio() instead.
- The _client() method of the wire protocol handler interface has been renamed to client().
- Wire protocol command handlers now return a wireprototypes.bytesresponse instead of a raw bytes instance. Protocol handlers will continue handling bytes instances. However, any extensions wrapping wire protocol commands will need to handle the new type.
- SSH protocol handler now advertises its name internally as "ssh-v1" instead of "ssh."
- File prefetching is now handled by registering a callback with scmutil.fileprefetchhooks.
- HTTP protocol handlers now advertises its internal name as "http-v1" instead of "http".
- context.basectx no longer implements __int__. Context instances will no longer cast to ints. Consumers should call ctx.rev() instead.
- templatekw.showdict() and showlist() are deprecated in favor of new (context, mapping) API. Switch the keyword function to new API and use templatekw.compatdict() and compatlist() instead.
- hgweb_mod.perms and wireproto.permissions have been removed. Wire protocol commands should declare their required permissions in the @wireprotocommand decorator.
- The WSGI request object no longer exposes a form attribute containing parsed query string data. Use the qsparams attribute instead.
- hgweb.hgweb_mod.permhooks no longer take a wsgirequest instance as an argument.
- hgweb @webcommand functions must use the new response object passed in via "web.res" to initiate sending of a response. The hgweb WSGI application will no longer start sending the response automatically.
- Various helper functions in hgweb.webutil no longer accept a templater instance. Access the templater through the "web" argument instead.
- Various functions in hgweb.webutil now take a modern request object instead of "wsgirequest".
- @webcommand functions now only receive a single argument. The request and templater instances can be accessed via the "req" and "templater" attributes of the first argument. Note that the request object is different from previous Mercurial releases and consumers of the previous "req" 2nd argument will need updating to use the new API.
- The old "wsgirequest" class for handling everything WSGI in hgweb has been replaced by separate request and response types. Various high-level functions in the hgweb WSGI applications now receive these new types as arguments instead of the old "wsgirequest" type.
- The render(mapping) method of the templater has been renamed to renderdefault(mapping).
- httppeer.httppeer.__init__ now takes additional arguments. Instances should be obtained by calling httppeer.instance() or httppeer.makepeer() instead.
- The templater is no longer callable. Use templater.generate(t, mapping) instead of templater(t, **pycompat.strkwargs(mapping)).
- templatekw._showlist() is deprecated in favor of templateutil._showcompatlist(), which takes context in place of templ.
- Several generic string helper functions have been moved to utils.stringutil module.
- The util.Abort alias has been removed. Use error.Abort.
- merge.update() and merge.applyupdates() now return a class with named attributes instead of a tuple. Switch consumers to access elements by name instead of by offset.
- Utility functions related to process/executable management have been moved to utils.procutil module.
- localrepo.localrepository.featuresetupfuncs has been renamed to localrepo.featuresetupfuncs.
- localrepo.localrepository.filterpats was renamed to localrepo.localrepository._filterpats.
- Template filters should declare input data type and/or catch AttributeError, ValueError, TypeError, etc. as needed. See the doc of "registrar.templatefilters" for details.
- "wireproto" module no longer re-exports various types used to define responses to wire protocol commands. Access these types from the "wireprototypes" module.
- filelog.parsemeta() and filelog.packmeta() have been moved to the revlog module.
- procutil.popen() no longer supports text mode I/O.
- hook.hook() and hook.runhooks() may return a negative integer to denote that the process was killed by signal.
- filelog.filelog is now a standalone class and doesn't inherit from revlog. Instead, it wraps a revlog instance at self._revlog. This change was made in an attempt to formalize storage APIs and prevent revlog implementation details leaking through to callers.
- The fp argument is removed from cmdutil.export(). Use cmdutil.exportfile() instead.
- cmdutil.export() takes a formatter as an argument.
- patch.extract() is now a context manager. Callers no longer have to worry about deleting the temporary file it creates, as the file is tied to the lifetime of the context manager.
- The wire protocol peer's iterbatch() for bulk executing commands has been removed. Use peer.commandexecutor() instead.
- sshserver no longers looks for wire protocol command handlers in methods named do_. Use @wireproto.wireprotocommand to declare wire protocol command handler functions.
- Log-related utility functions has been renamed as follows:
- cmdutil.loglimit -> logcmdutil.getlimit
- cmdutil.diffordiffstat -> logcmdutil.diffordiffstat
- cmdutil._changesetlabels -> logcmdutil.changesetlabels
- cmdutil.changeset_printer -> logcmdutil.changesetprinter - cmdutil.jsonchangeset = logcmdutil.jsonchangeset

- cmdutil.displaygraph -> logcmdutil.displaygraph
- cmdutil.graphlog -> logcmdutil.graphlog
- cmdutil.checkunsupportedgraphflags -> logcmdutil.checkunsupportedgraphflags
- cmdutil.graphrevs -> logcmdutil.graphrevs
- cmdutil._makenofollowlogfilematcher -> logcmdutil._makenofollowfilematcher
- The following deprecated methods have been removed from context, with replacements:
- unstable() -> orphan()
- bumped() -> phasedivergent()
- divergent() -> contentdivergent()
- troubled() -> isunstable()
- troubles() -> instabilities()
- The following deprecated methods have been removed from obsolete, with replacements:
- _addprecursors() -> _addpredecessors()

New in Mercurial 4.5.3 (Apr 5, 2018)
- Bug Fixes:
- rebase: on abort, don't strip commits that didn't need to be rebased (issue5822)
- hgweb: garbage collect on every request
- amend: abort if unresolved merge conflicts found (issue5805)
New in Mercurial 4.5.2 (Mar 7, 2018)
- All versions of Mercurial prior to 4.5.2 have vulnerabilities in the HTTP server that allow permissions bypass to:
- Perform writes on repositories that should be read-only
- Perform reads on repositories that shouldn't allow read access
- The nature of the vulnerabilities is:
- Wire protocol commands that didn't explicitly declare their permissions had no permissions checking done. The web.{allow-pull, allow-push, deny_read, etc} config options governing access control were never consulted when running these commands. This allowed permissions bypass for impacted commands.
- The batch wire protocol command did not list its permission requirements nor did it enforce permissions on individual sub-commands.
- Mercurial 4.5.2 fixes these vulnerabilities by:
- Performing permissions checking on all wire protocol commands, not just commands that list their permissions.
- Checking permissions on sub-commands issued to the batch command.
- Backwards Compatibility Changes:
- The "batch" wire protocol command now enforces permissions of each invoked sub-command. Wire protocol commands must define their operation type or the "batch" command will assume they can write data and will prevent their execution on HTTP servers unless the HTTP request method is POST, the server is configured to allow pushes, and the (possibly authenticated) HTTP user is authorized to perform a push.
- Wire protocol commands not defining their operation type in "wireproto.PERMISSIONS" are now assumed to be used for "push" operations and access control to run those commands is now enforced accordingly.
- Bug Fixes:
- fileset: don't abort when running copied() on a revision with a removed file
- date: fix parsing months
- setup: only allow Python 3 from a source checkout (issue5804)
- annotate: do not poorly split lines at CR (issue5798)
- subrepo: don't attempt to share remote sources (issue5793)
- subrepo: activate clone pooling to enable sharing with remote URLs
- changegroup: do not delta lfs revisions
- revlog: do not use delta for lfs revisions
- revlog: resolve lfs rawtext to vanilla rawtext before applying delta
New in Mercurial 4.5 (Feb 6, 2018)
- NEW FEATURES:
- revert --interactive:
- The revert command now accepts the flag --interactive to allow reverting only some of the changes to the specified files.
- Accessing hidden changesets:
- Set config option 'experimental.directaccess = True' to access hidden changesets from read only commands.
- githelp extension:
- The githelp extension provides the hg githelp command. This command attempts to convert a git command to its Mercurial equivalent. The extension can be useful to Git users new to Mercurial.
- Largefiles changes:
- largefiles: add a 'debuglfput' command to put largefile into the store
- largefiles: add support for 'largefiles://' url scheme
- largefiles: allow to run 'debugupgraderepo' on repo with largefiles
- largefiles: convert EOL of hgrc before appending to bytes IO
- largefiles: explicitly set the source and sink types to 'hg' for lfconvert
- largefiles: modernize how capabilities are added to the wire protocol
- HGWEB CHANGES:
- hgweb now shows more information about commits: phase (if it's not public), obsolescence status (with a short explanation and links to the successors) and instabilities (e.g. orphan, phase-divergent or content-divergent).
- Client-side graph code has been simplified by delegating more work to the backend, so /graph page is now more in sync with /log page, visually and feature-wise. Unfortunately, this code change means that 3rd-party themes for 4.5+ are required to have graphentry.tmpl template available (copy it from the base theme if you don't use %include and then reference it in map file) and render entries in graph.tmpl -- look at one of the core themes to see what it needs to look like. JS functions that create graph vertices and edges are now available in Graph.prototype, making it possible to call the original functions from custom theme-specific functions if needed.
- Graph now shows different symbols for normal, branch-closing, obsolete and unstable commits, and marks currently checked out commit with a circle around its graph node.
- There's also now json-graph API endpoint that can be used for rendering commit graph in 3rd-party applications.
- Other Changes:
- When interactive revert is run against a revision other than the working directory parent, the diff shown is the diff to apply to the working directory, rather than the diff to discard from the working copy. This is in line with related user experiences with 'git' and appears to be less confusing with 'ui.interface=curses'.
- Let 'hg rebase' avoid content-divergence by skipping obsolete changesets (and their descendants) when they are present in the rebase set along with one of their successors but none of their successors is in destination.
- A new experimental config flag, 'rebase.experimental.inmemory', makes rebase perform an in-memory merge instead of doing it on-disk in the working copy.
- The HGPLAINEXCEPT environment variable can now include color to allow automatic output colorization in otherwise automated environments.
- A new unamend command in uncommit extension which undoes the effect of the amend command by creating a new changeset which was there before amend and moving the changes that were amended to the working directory.
- A '--abort' flag to merge command to abort the ongoing merge.
- An experimental flag '--rev' to 'hg branch' which can be used to change branch of changesets.
- bundle2 read I/O significantly improved
- bundle2 memory use significantly reduced during read
- clonebundle: it is now possible to serve the clonebundle using a git-lfs compatible server.
- templatefilters: add slashpath() to convert path separator to slash (issue5572)
- A new experimental config flag, 'inline-color-diff', adds within-line color diff capacity
- histedit: add support to output nodechanges using formatter to help with editor integrations
- BACKWARDS COMPATIBILITY CHANGES:
- log --follow-first -rREV, which is deprecated, now follows the first parent of merge revisions from the specified REV just like log --follow -rREV.
- log --follow -rREV FILE.. now follows file history across copies and renames.
- transaction: register summary callbacks only at start of transaction
- hgweb's graph view no longer supports browsers that lack support
- hgweb: only include graph-related data in jsdata variable on /graph pages
- graphlog: add another graph node type, unstable, using character *
- remove: print message for each file in verbose mode only while using '-A'
- BUG FIXES:
- Bookmark, whose name is longer than 255, can again be exchanged again between 4.4+ client and servers (issue5165)
- The convert extension works with bzr < 2.6.0 again (issue5733)
- Mercurial will now attempt to use hardlinks on NTFS on Windows (issue4580)
- The revset x^:: is now correctly parsed as (x^):: instead of being an error (issue5764)
- Setting the diff.noprefix configuration option no longer breaks the --stat flag on hg diff (issue5759)
- hg outgoing now honors :pushurl paths from hgrc (issue5365)
- log: translate column labels at once (issue5750)
- patch: improve heuristics to not take the word diff as header (issue1879)
- templater: look up symbols/resources as if they were separated (issue5699)
- http and ssh: support for emitting extra debug logs about requests as they happen
- API CHANGES:
- bundlerepo.bundlerepository.bundle and bundlerepo.bundlerepository.bundlefile are now prefixed with an underscore.
- Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos.
- dirstate no longer provides a 'dirs()' method. To test for the existence of a directory in the dirstate, use 'dirstate.hasdir(dirname)'.
- mapping does not contain all template resources. use context.resource() in template functions.
- text=False|True option is dropped from the vfs interface because of Python 3 compatibility issue. Use util.tonativeeol/fromnativeeol() to convert EOL manually.
- wireproto.streamres.__init__ no longer accepts a reader argument. Use the gen argument instead.
- exchange.getbundlechunks() now returns a 2-tuple instead of just an iterator.
- bundle2 parts are no longer seekable by default
- memfilectx: the changectx argument is now mandatory in constructor
New in Mercurial 4.5 RC (Jan 23, 2018)
- NEW FEATURES:

- bundle2 parts are no longer seekable by default
- memfilectx: the changectx argument is now mandatory in constructor
New in Mercurial 4.4.2 (Dec 2, 2017)
- NOTABLE CHANGES:
- Stricter command option parsing:
- Mercurial can now optionally parse "early" options (-R/--repository, --cwd, --config, --debugger, and --profile) more strictly, for more secure integration with tools that invoke 'hg' commands. Setting HGPLAIN=+strictflags will parse these options more strictly, which prevents them from being injected as arguments to other flags.
- BUG FIXES:
- 'hg amend' now correctly handles deleted and removed files, as well as subrepos. (issue5732, issue5677)
- largefiles now correctly handles dropped standin files when updating largefiles.
- Fixed an issue with deleting symlinks to directories when ui.origbackuppath is set. (issue5731)
New in Mercurial 4.4.1 (Nov 27, 2017)
- Notable changes:
- Git and Subversion subrepos have been disabled by default to mitigate a potential security risk if files overlapping with a subrepo managed to be committed to a repository.
- Subrepos are now more paranoid about symlink traversal.
New in Mercurial 4.4 (Nov 2, 2017)
- NOTABLE CHANGES:
- Control whitespace settings for annotation on hgweb:
- /annotate URLs on hgweb now accept query string arguments to influence how whitespace changes impact results.
- The arguments "ignorews," "ignorewsamount," "ignorewseol," and "ignoreblanklines" now have the same meaning as their [annotate] config section counterparts. Any provided setting overrides the server default.
- HTML checkboxes have been added to the paper and gitweb themes to expose current whitespace settings and to easily modify the current view.
- Fast, heuristic copy-tracing:
- A new fast heuristic algorithm for copytracing which assumes that the files moves are either: renames in the same directory or moves in other directories with same names
- You can use this algorithm by setting 'experimental.copytrace=heuristics'. This setting performs full copytracing if both source and destination branches contains non-public changesets only.
- Other changes:
- Estimated time is more accurate with non-linear progress
- "hg status -v" can now show unfinished state.
- Added '--ignore-space-at-eol' diff option to ignore whitespace differences at line endings.
- show: use consistent node length in views
- show: decrease minimum displayed hash length from 5 to 4
- A new uncommit extension which provides 'hg uncommit' using which one can uncommit part or all of the changeset. This command undoes the effect of a local commit, returning the affected files to their uncommitted state.
- 'hg clone --uncompressed' uses clone bundles when possible
- 'hg annotate --skip' now prints a '*' on lines with skipped revisions
- New 'commands.update.check' feature to adjust constraints on when 'hg update' will allow updates with a dirty working copy.
- Add an experimental -L/--line-range FILE,FROMLINE:TOLINE option to 'hg log' command to follow the history of files by line range. In combination with -p/--patch option, only diff hunks within specified line range will be displayed. Feedback, especially on UX aspects, is welcome.
- Print warning when fsmonitor isn't being used on a large repository
- BACKWARDS COMPATIBILITY CHANGES:
- The config option for copytrace 'experimental.disablecopytrace' is now replaced with 'experimental.copytrace' which defaults to 'on'. If you need to turn off copytracing, add '[experimental] copytrace = off' to your config.
- 'hg clone --stream' should now be used instead of --uncompressed. --uncompressed is marked as deprecated and is an alias for --stream. There is no schedule for elimination of --uncompressed.
- The 'experimental.updatecheck' name for the new 'commands.update.check' feature is now deprecated, and will be removed after this release.
- Mercurial subrepositories are now shared instead of cloned when the parent repository is shared. This prevents dangling subrepository references in the share source. Previously shared repositories with cloned subrepositories will continue to function unchanged.
- Push no longer triggers a pushkey hook when updating phases. Use the new 'txnclose-phase' and 'txnclose-phase' hooks instead. (Applies when both server and client use version 4.4 or above).
- BUG FIXES:
- Core rebase algorithm has been rewritten to be more robust (issue5578, issue5630)
- Creating a share of a repository with a Mercurial subrepository will now share the subrepository (issue5675)
- PERFORMANCE IMPROVEMENTS:
- improved performance when many aliases are defined
- API CHANGES:
- remove peer.batch():
- Replace with peer.iterbatch().
- Other Changes:
- @peer.batchable can no longer emit local values
- @peer.batchable functions must now yield exactly 2 values
- Rename attributes on sshpeer to reflect peer API
- peer.peerrepository has been removed. Use repository.peer abstract base class to represent a peer repository.
- revset.stringset() now takes 'order' as the last argument.
New in Mercurial 4.3.3 (Oct 3, 2017)
- Prevent crashes when clearing progress bar. (issue5684)
- rebase: move bookmarks with --keep (issue5682)
New in Mercurial 4.3.2 (Sep 18, 2017)
- restore compatibility with older versions of Python 2.7 by not using a bytearray with struct.unpack_from()
- restore mingw compatibility for setup.py
- hgwebdir: read 'web.template' untrusted (plugs potential security issue)
- repair: preserve phase when not using generaldelta (issue5678)
- ssh: fix flakey ssh errors on BSD systems
- restore error handling behavior around certain I/O errors; the regressed behavior could result in transactions not being properly rolled back if stdio handles encountered errors (issue5658)
- templatekw: choose {latesttag} by len(changes), not date (issue5659)
- record: fix revert -i for lines without newline (issue5651)
- mq: create non-lossy patches, also with custom global diff configuration
New in Mercurial 4.3.1 (Aug 12, 2017)
- Fixes a release oversight.
New in Mercurial 4.3 (Aug 11, 2017)
- Notable changes:
- experimental amend extension providing the amend command
- experimental sparse extension
- Support for Python 2.6 has been dropped.
- Bundles created by the strip extension now store phase information. It will be restored when unbundling.
- The strip extension now removes relevant obsmarkers. If a backup requested (the default), the obsmarkers are stored in the backup bundle and will be restored when unbundling.
- hg show work (from the experimental show extension) now displays more info
- hg show stack is a new view for the current, in-progress changeset and others around it
- Mitigation for two security vulnerabilities
- CVE-2017-1000115:
- Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.
- CVE-2017-1000116:
- Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.

New in Mercurial 4.2 (May 3, 2017)
- Notable changes:
- Pager support has been moved into core and is now enabled by default. This is now controlled with the ui.paginate setting. Note that in 4.2-rc, the ui.paginate option was named pager.enable. The old name has been dropped in the final release. If you had turned pagination off using pager.enable=False, please update your config.
- Color support has also been moved into core and is now enabled by default (the ui.color setting now defaults to 'auto').
- The new experimental 'show' extension provides a way to view various information about your repository in an ergonomic way. It is deliberately designed for human consumption and not for scripting, so it doesn't carry the same backward compatibility guarantees as other commands. See 'hg help -e show' for more information.
- commands:
- Pager support has been added to the 'branches', 'files', 'status', 'summary', and 'tags' commands, as well as the '--patch', '--list', and '--stat' options of hg shelve.
