bitget is upgraded:
It now accepts positive Signed encoded integers.
It now supports the new uint64 and int64 types of encoded integers.
For decimal numbers: bits with indices > 52 can now be retrieved (up to log2(number_properties("huge")) = 1024).
For decimal numbers x > 2^52, queried bits below %eps (indices < log2(x)-52) now return Nan instead of 0.
Several bits can now be retrieved from each component of an input array.
bitset is upgraded:
It now accepts positive Signed encoded integers.
It now supports the new uint64 and int64 types of encoded integers.
For decimal numbers: bits with indices > 32 can now be set (up to #1024).
Several bits can now be set for each input component.
Distributive scalar inputs are now accepted.
bitstring function added.
edit now accepts a line number as text (like "23").
profileEnable, profileDisable, profileGetInfo could be used to instrument functions and gather execution information within Scilab.
prettyprint is upgraded:
Integer and Text input are now actually supported.
HTML is now supported as output format.
Default input arguments can be skipped instead of still having to be provided.
The result string is better formatted to be easily wrappable and indented.
mesh2d has been introduced to compute a 2d mesh from vectors (x,y) of points.
loadmatfile is upgraded:
Octave native text data files can now be read.
Automatic detection of the input data format implemented.
-toStruct option added, to return results in a structure instead of in the calling environment.
jremove is optional and clear could be used to release Java objects mapped to Scilab.
blockdiag is introduced to improve, replace, and extend sysdiag to strings.
assert_checkequal is upgraded:
support added for Nan and void in lists, Nan in sparses, implicit lists, graphic handles, macros, libraries, and built-in.
For arrays of matching typeof and sizes, and for lists of matching lengths, the failure message now indicates the index and values of the first mismatching elements.
diophant is improved:
Encoded integers are accepted, in addition to decimal numbers. Only integer solutions are then searched.
When there is no solution, [] is returned.
When there is an infinite number of solutions, the err flag has a specific value.
The output size gets the input's size.
csvRead and csvTextScan are now implemented without extra copies.
editvar GUI support copy-paste of strings removing quotes.
calendar can now display formatted calendars.
xmlSetValues clones setPreferencesValue that is now obsolete.
unique is upgraded to:
return the number of occurrences of distinct entities found in the input array.
return distinct entities in their initial order (rather than sorted), with the "keepOrder" option.
consider all Nan values as the same one, with the "uniqueNan" option.
ellipj function introduced, to compute the sn, cn, dn, ns, nc and nd Jacobi elliptic functions.
riccati is upgraded:
riccati(H) and riccati(H,E) syntaxes added, to describe the Riccati equation through its Hamiltonian H or (E,H) pencil.
The residual is returned as a new 3rd output argument.
When no solution is found, X=[] | X1=[] is returned instead of yielding an error.
hallchart is upgraded:
The default set of modules is set automatically, according to data bounds.
Handles of the grids and labels are returned. Post-processing them becomes easy.
Named colors accepted; better default colors.
Improved placement of labels.
playsnd is upgraded:
the name of a wav file can now be specified (instead of the sound data).
the input sound can now be repeated a given number of times.
the modal/non-modal processing is improved.
nicholschart is improved: more neutral default frame color; improved labels positionning; colors can now be specified by their predefined name or "#RRGGBB" hexa code; a structure of handles is now returned to easily postprocess both subframes and the set of labels.
sciargs returns a column instead of formerly a row.
Booleans and encoded integers can now be concatenated together, as in [%f int8(-5)].
gsort can now perform multilevel sorting. This noticeably allows sorting completely complex numbers.
factorial can be used now from n=171 up to n=10^14.
intersect now supports complex numbers.
setdiff now supports complex numbers.
twinkle can now blink together several hierarchically independent objects, like a curve and its labels, etc.

Hypermatrices are now accepted as haystack.
The probing direction can now be numeric: 1, 2, ..
Returned indices can now be formatted with the new option indType.
There were no unit tests. More than 100 tests are added.
datafit is now able to fit weighted data. It now supports any gap function vectorized for Data points, and so is much faster. It now accepts any matrix of parameters (not necessarily a colum). It now returns the average Mode-to-data distance, and the termination status for the quasi-Newton algo.
tree_show is upgraded:
New rootTitle and styles optional inputs.
New arrayByFields option, to allow displaying each array component as an object in its whole.
Improved layout: detailled indices for 2D arrays, simplified symbols, etc.
The content of implicitlist objects, and information for Scilab functions and libraries of functions are now displayed.
nchoosek is introduced, to compute the binomial coefficients.
The left .. and right ./. Kronecker divisions are now implemented, for arrays of decimal or complex numbers.
perms can now build and return only unique permutations, without duplicates.
Most of graphic objects can be moved interactively in opened figures.
circshift is introduced.
atomsGetInstalledPath is no longer sensitive to the case or completeness of the modules names. Providing the modules versions is now optional.

CURVE_c settings did not always display a window.
Exporting all layers from a diagram will generate one unique file per layer.
API/ABI modification:
Functions could return zeros arguments, the following gateway functions have been updated:
on APIv5 C CheckOutputArgument(ctx, min, max) the min argument should be set to 0 if needed.
on APIv5 C getNbOutputArgument(ctx) the return value could be 0
on APIv6 C++ the _iRetCount argument value could be 0.
On APIv6 C++, a virtual method has been added on internal types which break the ABI. Toolboxes need to be recompiled.

#14606: Memory used by variables returned by [names,mem]=who() was always zero.
#14610: x = ric_desc(H,E) always yielded an error. [x1,x2,residual] = ric_desc(..) returned a wrong residual value.
#14642: No more "r" carriage return with printf.
#14655: bitset worked only element-wise, without accepting mixed scalar and array inputs.

#15359: twinkle was not able to blink several independent objects.
#15360: numer and denom were poor and duplicates of the .num and .den fields of rationals. They are removed.
#15368: freson silently returned frequencies not corresponding to a maximum, or returned [] instead of some still computable maxima frequencies.
#15392: comet and comet3d did not allow specifying colors with colors names.
#15393: In a new figure, nicholschart plotted nothing. The default frame color was a flashy cyan. The position of gain labels could be puzzling. It was not possible to specify colors by their names. Postprocessing the frames and the set of labels was not easy.
#15421: A new smarter default grid_style was required since smart lines styles #7-10 are available.
#15425: The Kronecker product a .*. b failed when a or b or both are hypermatrices, with one or both being polynomials or rationals.
#15428: repmat was slow. Its code did not use kron and was complex.
#15431: The empty matrix [] and its non-convertibility were poorly documented.
#15451: The code was not adapted to use lucene 4.10 in Debian.
#15514: The set documentation page needed to be overhauled.
#15517: factorial could be actually used up to only n=170.

#15577: edit did not accept a line number as text, as with edit linspace 21.
#15580: det(sparse([],[])) yielded an error.
#15581: display of complex matrix was ugly.
#15595: unique was not able to return distinct values in their original order, without sorting them. A keepOrder option now allows it.
#15628: with_tk was a duplicate of with_module('tclsci'). It is removed.
#15643: Features with the signed zero -0 were not documented.
#15668: save(filename) saved all predefined Scilab constants %e %pi etc.. (regression)
#15680: loadmatfile could not return variables in a structure instead of into the calling environment.
#15701: AB was not faster when A is square and triangular.

#15734: intersect did not support complex numbers.
#15734: Trivial infinite loop could not be interrupted.
#15737: setdiff was wrong with complex numbers.
#15742: The compatibility_functions module should be merged in the m2sci one.

#15745: diophant(0,0,m), diophant([p 0],q), diophant([0 p],q) with m0 and p>q were wrong. There was no flag for cases with an infinite number of solutions. When there is no solution, some values were returned anyway, instead of []. In this case, the documented definition of the err value was dubious. Decimal numbers and integers were accepted, but not encoded integers. Inf and NaN input coefficients were not rejected.
#15812: On assigning variables the source variable may become become corrupted
#15821: fac3d and fac3d1 were still in Scilab 6.0 despite they were tagged obsolete 14 years ago in Scilab 4.1
#15825: gsort could not sort completely dense matrices of complex numbers.
#15840: grand(1,"prm",m) yielded an unsqueezed size([size(m) 1]) hypermatrix
#15861: The overloadname internal macro defined in CACSD was a duplicate of typeof(,"overload"). It is removed.
#15874: The scatter3 function name was an unfounded naming exception. It had to be renamed scatter3d.
#15921: Xcos user's function scifunc_block_m block: any < in the expression was not displayed on the block's icon.
#15934: The ^ hat page wrongly indicated that ^ applied to a rectangular matrix not being a vector is done element-wise.
#15948: xlabel, ylabel, zlabel and title needed to be upgraded.
#15964: A complex empty sparse matrix could be obtained after insertion.
#15965: plot(x,y) did not accept y as encoded integers.
#15967: setdiff(1,[]) was [] instead of 1. setdiff(a,[],..) was not enough tested.
#15969: Fix spelling
#15974: msprintf("%d", %nan) did not return Nan
#15977: The documentation for wavread(..,'info') had a mistake. The wavread page deserved some improvements.
#15978: The writewav page in english said that input data are one column per channel, instead of one row per channel. In addition, in case of writing error, savewave kept the output file open and locked.
#15979: EXPRESSION, CLR and DLR Xcos blocks did not (always) correctly display multicharacter exponents in expressions displayed in their icons.
#15981: wavread kept the wav file open and locked when returning on errors. It weakly managed the input file name. It claimed for invalid data formats instead of unsupported ones, with poor information about the current format vs the supported ones. Several error messages refered to a wrong function.
#15983: group regressed in 5.5.2 due to a too intrusive fix.
#15984: display scale was wrong with Retina dispplays on OSX..
#15995: patch was missing in surface plot (regression)
#15998: mfile2sci yielded an unsuitable warning when converting atan.
#16000: mfile2sci converted acoth using atanh and yielding a wrong warning message.
#16003: Zoom with mouse scroll wheel was broken on simple surfaces.
#16005: The intdec example was biased and not robust when changing sampling frequencies.
#16007: Non-integer index in sparse makes Scilab crash.
#16008: Uimenu .callback_type, .children, .handle_visible, .user_data properties, and using HTML styling in .label were not documented.
#16011: colorbar(umin, umax) did not work after plot3d2.
#16012: [struct() struct()] crashed Scilab.
#16013: Load previously saved environment with "File/Load environment" menu failed.
#16014: after x.a=1; x(:)=[] x.a was an empty list.
#16015: intg(a,b,f) called f(x) with x outside [a,b].
#16019: polarplot(x,Z) yielded an error when x is a vector and Z a matrix.
#16021: tand([-90 90]) answered [Nan Nan] instead of [-Inf, Inf]. cotd([-90 90]) answered [Nan Nan] instead of [0 0]. 1 ./cosd([-90 90]) answered [Inf -Inf] instead of [Inf Inf].
#16026: For atanh, neither the documentation pages nor the m2sci converter were up to date.
#16028: The length of intdec(intdec(x, r), 1/r) was most often different from length(x).
#16046: After w=ssrand(2,3,4), []+w, []-w, w+[] and w-[] yielded an "operation +/- []" warning.
#16051: undefined list elements could be of 2 distinct typeof "void" or "listundefined" according to the way they are created.
#16053: plot(,"color",c) no longer supported standard abbreviated color names c like "k" for black.
#16062: tbx_make did not allow easily to force building all toolbox sections without the toolbox builder (if any). tbx_make(Dir,"*") now does it.
#16064: tbx_make(Dir,'localization') did not update .mo files from .po.
#16065: Building help pages including some scilab:image tags used and finally deleted the current on-screen figures (if any)!
#16067: The display of matrices of signed integers was misaligned (regression of 6.0.0 vs 5.5.2)
#16071: prettyprint(complex(1,%nan)) omitted the "+" in 1 + Nani. It printed positive exponents with a useless "+". For any input nul polynomial, the string result never included the name of the variable. Default input arguments could not be skipped. ExportFormat was uselessly case-sensitive. For tex|latex: for text input, $ % & { } ~ and ^ special characters were not protected ; spaces were not protected, all words were concatenated ; for polynomials and rationals, the result string could be extremely long and not easily wrappable. For MathML: "

New code productivity features: full-featured debugger, profiler and coverage tool, and "lint"-like commands.
Newsfeed, providing a continuous feed of news, tips, and general communication from the community and from Scilab Enterprises.
Licensing change: Scilab is now released under the terms of the GNU General Public License (GPL) v2.0 (but continues to be available under the terms of the CeCILL v2.1).
New language parser and interpreter, ensuring:
Support for bigger data sets: dynamic memory usage. No need for "stacksize" anymore.
Xcos also uses the new re-written Scilab engine.
OTHER FEATURE CHANGES:
Valgrind error detection added to test_run (on Linux only)
Addition or subtraction with an empty matrix now return an empty matrix.
SSE2, Streaming SIMD Extensions 2 support is now mandatory to run Scilab on Linux i686.

New in Scilab 6.0.0 Alpha 1 (Jul 30, 2015)

Includes a major rewrite of Scilab's internal core. The changes to the visible aspects of the software are limited. The first big internal change, is a complete new language parser and interpreter, with the following changes:
The language is much more coherent and predictable,
The grammar is stricter, but more consistent,
Error handling has been improved (but may still be limited in the alpha: please report issues you find),
The language has slightly better compatibility with Matlab's language (for example control instructions such as switch/ case statements).
The language changes are not all backward-compatible. You will have to update your scripts/programs/modules, but it
Will be very simple in pretty much all cases. In particular, the following changes may require modifications to existing code:
Literal strings cannot mix single-quote and double-quote delimiters: they have to start and finish with either both single-quotes, or both double-quotes,
Usage of commas (to put multiple instructions on the same line) has been clarified: it can not be used following control instructions such as try,
Three dots or more are not supported anymore.
The second big internal change, is the ability to manipulate bigger data sets, without exhausting system resources. This includes in particular:
A much better memory management. Memory usage
is now only limited by the machine's memory. This was a much-needed, and much-requested feature.
There is no need anymore for stacksize,
Support for bigger data sizes, in particular with better support for HDF5 files,
Some new and improved data types: 64-bit integers; ability to define user types in C++ modules. Also, matrices with more than two dimensions are now implemented natively.
Native data structures (cell, struct), as well as multidimensional matrices, which yield, in most cases, better performance, both in memory usage, and execution speed. There could be some performance degradation in some cases: please feel free to report them.
These changes may not amount much to end-users, but they were much needed, much worked-on, improvements to the Scilab platform. These improvements will enable further improvements in the future, in terms of code management, development tools (debugger, analyzer...), as well as improvements to other part of the platform (Xcos...) that would not be possible without this release.
Main Limitations:
Several important parts of the platform are not functional in this alpha:
Xcos is not functional yet; the editor is not working yet at in this alpha 1 (it will in the final release, for sure). The simulator has been ported but is still not usable,
The debugging and profiling capabilities present in the 5.5.2 version are not ported to 6; most likely it will be replaced by completly new features.
ATOMS is functional, but since none of ATOMS modules currently on http://atoms.scilab.org/ have been ported, it is not of much use.

GRaphicS
Entire refactoring of Scilab graphic capabilities in order to solve the known issues of graphical cards compatibilities and many Scilab crashes.
Based on SciRenderer (rendering library based on JoGL), Scilab graphics have been rewritten to provide new graphic functionalities with:
Better performances,
Better stability,
2-D zoom using the mouse wheel,
New 3-D zoom capabilities,
Rotation available through the mouse right-click.
SciRenderer is a free and open source library developed by Scilab Enterprises for 2-D and 3-D rendering of scientific data.
Improved graphic exports:
Off-screen export (Scilab will not open a window to export with driver).
New bitmap formats supported: PNG, JPEG and BMP in the driver function.
New vectorial formats supported: PDF and SVG in the driver function.
Many portability issues fixed.
Obsolete value for line_style property:
0 and 1 are equivalent values for SOLID rendering.
A warning message will be displayed if the user tries to set this property to 0. Setting this property to 0 will no more be supported in Scilab 5.4.1.
datatips tool improved on several aspects:
It is now possible to manage directional arrows as well as square mark markers.
The automatic label placement has been improved to avoid the overlapping with the curve.
It is now possible to have painted box or box free labels.
Markers can now be selected and moved using the arrow keys or deleted with the "Del" key.

Bug # 10637 fixed - xs2svg crashed when the first input argument was not a figure handle. An error message is now displayed.
GUi:
Uicontrols tooltip can now be managed using the new TooltipString property.
Figure closure can now be managed by the user (confirmation, ...) through the CloseRequestFcn property.
F5 and F6 change the focus of the docked element. Improvement in the refresh of the docked elements.
A 'Console' handle has been created and can be obtained by calling get(0):
uimenus now appear as Children of this handle when they are added to the console,
the ShowHiddenHandles property enables the user to make some hidden graphic objects visible.
Scilab Console and graphic figure menus are now
uimenus.
They are hidden by default. To see them in the children list, use set(get(0), "ShowHiddenHandles", "on")
New uicontrols added:
'image' style uicontrol: display, transformation and various other operations on images.
'table' style uicontrol: display data in a table form (read-only).
The Value property can now contain non-integer values and allows to take full advantage of slider style uicontrols.
See Bug # 7380.
Figure resizing can now be managed by the user (uicontrol position setting, ...) through the resizefcn property.
cli coNSole (GNU/liNUx aND Mac oS x oNly)
Wide characters supported. Multiline command supported. Command line display improved.
List of shortcuts in NW/NWNI mode:
CTRL+W removes the previous word.
CTRL+U removes everything from the current position to the beginning of the line.
UP or Ctrl+P recalls the previous line.
DOWN or Ctrl+N recalls the next line.
TAB for completion. Scilab displays a list of all names (functions, variables) that start with the characters already typed by the user.
Ctrl + A or HOME moves the cursor to the beginning of current line.
Ctrl + B or LEFT moves the cursor one character to the left.
Ctrl + D or DELETE deletes the current character.
Ctrl + E or END moves the cursor to the end of command line.
Ctrl + F or RIGHT moves the cursor one character to the right.
Ctrl + H or BACKSPACE deletes the previous character.
Ctrl + K kills the command line from cursor to the end. w Alt+B or Ctrl+LEFT moves one word left.

eleMeNtaRy FUNctioNS
New functions:
dec2base function added. See SEP #75
nthroot function added. See SEP #78
linspace and logspace deprecate the use of non-integer values as third input argument.
The toeplitz macro is now vectorized.
SpaRSe
qmr function updated and modified.
Calling qmr(F, Fp, x) where F is a function returning A*x and Fp a function returning A'*x is deprecated. Use qmr(F, x) instead where F prototype is:
function y = F(x, t)
where t is used to make F return A*x or A'*x. Same behavior has been implemented for qmr( ..., M1, M1p, M2, M2p).
Scilab:
save/load functions can export / import Scilab data to SOD format:
Scilab data are saved and loaded using a standard, HDF5-based, documented, and fully tested: Scilab Open Data format (SOD).
Graphic handles can be saved under the SOD format. w 'save' writes data to HDF5 format when using new calling sequence save("filename.sod", "a", "b", "c"). This format is Scilab 6 compatible.
'save' displays a message when using old calling sequence save("filename", a, b, c) and writes data in old Scilab binary format. This format will not be supported by Scilab 6.
The 'matfile2sci' function now converts MAT-files to SOD files.

./configure && make all && make distclean == tarball (ie, make distclean is cleaning all the elements)
In the source tree of Scilab, ant target "build-example" added in order to build only the javasci examples (cd modules/javasci && ant build-example)
Source reorganisation:
New module added call_scilab: the goal of this module is to highlight the possibility to call Scilab engine from other languages.
"SCI/modules/output_stream/includes/error.h" renamed to "do_error_number.h"
Help & Tests:
Some equations in the documentation converted to the MathML format (bugs #4180 & #4182)
Page "Compile and run with Javasci" added
Examples in javasci translated into english
Examples and unit tests added for the function find
Examples provided in the help of the function argn
Unit tests for the completion (GUI & NW/NWNI modes)
Minor improvements in the documentation of the ilib_* functions and fprintf
Unitary tests for isfield() function have been added
Enhancement:
isfield() now accepts matrix of strings (fieldnames) as second input argument. Then, it returns a matrix of booleans.
test_run() now accepts "skip_tests" as optionnal argument (3rd argument), if present, the second input argument of test_run is no more the list of tests to launch but the list of tests to skip. For example, test_run("time",["bug_1506" "bug_793"],"skip_tests");
test_run() : The following tags have been added :
If the operating system isn't Windows, the test is skipped.
If the operating system isn't an unix OS, the test is skipped.
If the operating system isn't Linux, the test is skipped.
If the operating system isn't MacOSX, the test is skipped.
License:
Examples in SCI/modules/javasci/examples/ are now released under the public domain
Internal API:
GetLengthStringMatrixByName function added in stack3.h (return length of strings)
