[Vadim Zeitlin]

February 19, 2018 -- The wxWidgets team is pleased to announce a new
release of our open source framework for the development of native
cross-platform applications in C++.

wxWidgets 3.1.1 is the second release in the 3.1 development
branch and is now available at

https://github.com/wxWidgets/wxWidgets/releases/tag/v3.1.1

Compared to the stable 3.0.x series, this version brings many
improvements and even more bug fixes, please see the change log

https://raw.githubusercontent.com/wxWidgets/wxWidgets/v3.1.1/docs/changes.txt

for the incomplete list of the most important ones. Here is the
maximally condensed summary of the changes compared to 3.0:

- New features: support for mouse gesture events (GSoC 2017 project);
fractional pen widths in wxGraphicsContext; arbitrary label windows in
wxStaticBox; markup in wxDataViewCtrl items text; better support for high DPI
monitors; support for ZIP 64 files; much improved accessibility support under
MSW.
- New classes: wxActivityIndicator, wxAddRemoveCtrl,
wxAppProgressIndicator, wxNativeWindow, wxPowerResourceBlocker,
wxSecretStore.
- And methods: wxDateTime::GetWeekBasedYear(), wxListBox::GetTopItem(),
wxProcess::Activate(), wxTextEntry::ForceUpper(), several ones in
wxRendererNative, wxStandardPaths::GetUserDir(), wxUIActionSimulator
::Select() and many others.
- Significant improvements to: wxBusyInfo, wxNotificationMessage.
- Latest versions of all bundled 3rd party libraries, including all the
security fixed and support for WebKit 2 and GStreamer 1.7 under Unix.
- Revamped OpenGL support better suited to modern OpenGL (3.2+).
- Further C++11 support improvements.
- New CMake-based alternative build system.
- Support for latest compilers: MSVS 2017, g++ 7, clang 6.
- A lot of bug fixes, especially in wxGTK3 and wxOSX/Cocoa ports.
- New experimental wxQt port.


This release is a "development" one as it makes (very few)
incompatible API changes compared to 3.0 and does not guarantee the
ABI stability, unlike the 3.0.x series. It is not inherently more
buggy or less stable than the "stable" releases and you're encouraged
to use it. If you're already using 3.0, upgrading shouldn't require
any special effort, so please try it out.

We hope that you will enjoy using the new release!
