This file details the changes between Scilab 2023.1.0 (this version), and the previous stable 6.1.1 release (including information from 2023.0.0). For changelogs of earlier releases, please see Scilab 2023.0.0.
Summary:
Please report anything we could have missed, on the mailing lists or the bug tracker.
For a high-level description of the main new features of this release, please consult the embedded help. It is also available as the "What's new" page of the help, by simply typing help in Scilab console.
In summary, the main new features and additions are:
edit_curv() is upgraded. Newly implemented features:
curl as default on atomsDownload() for all OS to handle local file repositories.cat() accepts arrays of different but compatible types according to [,] and [;] rules.tbx_make(".", "help", lang) builds the documentation restricted to a given language.In summary, the main new features and additions are:
auto_stretch property has been added for axes handles.http_get() function now sets accept-encoding flag.verbose parameter added to http_get().atomsInstall() will now try to build a package (containing only Scilab code) locally from sources when no compatible binary version is found.toJSON(var, filename, indent) implemented, after toJSON(var, filename).fromJSON and toJSON processing of tab (ascii(9)) is changed.for c = h,.., end now accepts a hypermatrix h and iterates over its columns matrix(h, size(h,1),-1).covWrite("html", dir) results is improved.tbx_make(".", "localization") can now update files of translated messages according to new gettext entries in the code.All these functions and features will be removed in Scilab 2025.0.0 (October 2024):

Please use "root" instead.frexp is now an internal function. Please use [m,e]=log2(x) instead.GNU autotools have been updated to :
All builds require a C++17 compiler. Toolboxes might also want to use this standard by specifying -std=c++17 as a CFLAGS under Linux and macOS.
Migration to Microsoft Visual Studio 2022 and Intel® oneAPI HPC Toolkit 2022.3.
macOS: The build environment has been migrated to conda and now relies on clang and libc++, hence (existing) toolboxes with binary gateways have to be (re)compiled using the same conda environment (see https://gitlab.com/scilab/scilab/-/wikis/Developers/setup-Scilab-repository-macOS)
32-bit Windows platforms are no more supported (no binary versions released).
Scilab embedded JVM is Java 8.
