wxWidgets 3.3.1 Release Notes ============================= Welcome to the latest release of wxWidgets, a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls. wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at: * https://www.wxwidgets.org/ Documentation is available online at: * https://docs.wxwidgets.org/3.3.1/ wxWidgets sources and binaries for the selected platforms are available for download from: * https://www.wxwidgets.org/downloads/ or, for a more more permanent but less convenient to use link, from * https://github.com/wxWidgets/wxWidgets/releases/tag/v3.3.1/ Please see https://docs.wxwidgets.org/3.3.1/overview_install.html for full installation instructions.

Please see the change log for the more complete list: https://raw.githubusercontent.com/wxWidgets/wxWidgets/v3.3.1/docs/changes.txt Note that in spite of all these changes, wxWidgets 3.3.1 is almost fully compatible with wxWidgets 3.2 and updating the existing applications to use it shouldn't require much effort. However please make sure to read the "INCOMPATIBLE CHANGES" section of the change log above when upgrading to be aware of the breaking changes in it. Supported Platforms ------------------- This version of wxWidgets supports the following primary platforms: * Windows 7, 8, 10 and 11 (32/64 bits). * Most Unix variants using the GTK+ toolkit (version 2.6 or newer) * macOS (10.10 or newer) using Cocoa (x86-64 or ARM). There is some support for the following platforms: * Most Unix variants with X11 * Most Unix variants with GTK+ 1.2 * Most Unix variants with Qt 5 or newer (experimental) All C++ compilers in common use are supported. Licence ------- For licensing information, please see the files: * docs/preamble.txt * docs/licence.txt * docs/licendoc.txt * docs/gpl.txt * docs/lgpl.txt * docs/xserver.txt Although this may seem complex, it is there to allow authors of proprietary, commercial applications to use wxWidgets in addition to those writing GPL'ed applications. In summary, the licence is LGPL plus a clause allowing unrestricted distribution of application binaries. To answer a FAQ, you don't have to distribute any source if you wish to write commercial applications using wxWidgets. However, if you distribute wxGTK or wxQt version of your application, don't forget that it is linked against GTK or Qt, which are covered by LGPL *without* exception notice and so is bound by its requirements. If you use TIFF image handler, please see src/tiff/COPYRIGHT for libtiff licence details. If you use JPEG image handler, documentation for your program should contain following sentence: "This software is based in part on the work of the Independent JPEG Group". See src/jpeg/README for details. If you use wxRegEx class, please see 3rdparty/pcre/LICENCE for PCRE licence details. If you use wxXML classes or XRC, see src/expat/COPYING for licence details. Reporting Bugs -------------- The wxWidgets bug tracker can be found here: * https://github.com/wxWidgets/wxWidgets/issues/ Please use the search function find any possibly relevant bugs before reporting new ones. Also please notice that often trying to correct the bug yourself is the quickest way to fix it. Even if you fail to do it, you may discover valuable information allowing us to fix it while doing it. We also give much higher priority to bug reports with patches fixing the problems so this ensures that your report will be addressed sooner.
