# Wx Release Notes

This document describes the changes made to the Wx application.

## Wx 2.5.4

### Improvements and New Features

- Release applications, tests, and documentation are now placed in their respective directories. Source SBOM with more packages.
  
  A `make release` application places only the necessary code in the release folder. The main change is that the documentation and examples are not part of the release folder anymore.
  
  `make release_docs` places the documentation in the released code under the `doc` folder.
  
  `make release_tests` places the tests in their own directory. It used to be the case that some source code was mixed with the tests, and this should not happen anymore.
  
  The Software Bill of Materials places the examples folders as if they are part of the `SPDX-otp-<app>-doc` packge, instead of placing examples as if they were running source code.
  
  Overall, this change cleans up many things that were not quite correct by definition, and everything should still continue to work as expected. To test a release, one can still run `./Install -minimal \`pwd\`` and add the release to the `PATH`. After that, one can run tests as usual, going into the released tests directory, entering `test_server` and running the emulator.
  
  Improves the source Software-Bill-of-Materials
  
  - The improvements adds new SPDX relations for `asmjit` and `zlib` to be `optional_components_of` the Erlang/OTP project.
  - The `autoconf` scripts in `make` and `erts` have now been categorised as `build_tool_of` the Erlang/OTP project.
  - All remaining `configure`, `configure.ac`, `config.h.in`, `Makefile.in`, `Makefile.src`, `EMakefile`, and `GNUMakefile` are now part of a specific SPDX package with relation `build_tool_of` the Erlang/OTP project.

  now returns a tuple not bug compatible with previous releases but needed.

  Own Id: OTP-10743

### Improvements and New Features

- The wx application now compiles and is usable with the unstable development
  branch of wxWidgets-2.9. Some functions are currently not available in
  wxWidgets-2.9 and their erlang counterparts are marked as deprecated. They
  will generate an error if called when linked against wxWidgets-2.9 libraries.
  This means that wx can now be built on 64bit MacOsX, but keep in mind that
  wxWidgets-2.9 is still a development branch and needs (a lot) more work before
  it becomes stable.

  Own Id: OTP-8126

### Improvements and New Features

- wxHtmlWindow class implemented.

  All exceptions from callbacks are now caught and written to the log.

  Some defines where wrong in 'wx.hrl'.

  `wx:batch/1` and friends could hang forever if for instance a breakpoint was
  set inside the fun. That caused all wx applications to hang.

  Added missing wxAuiPaneInfo constructor and destructor.

  Added wxAuiNotebookEvent and wxAuiManagerEvent.

  Calling non supported wxWidgets functions hanged instead of crashed.

  Update OpenGL to version 3.1 and added some of the missing glu functions.

  Fixed wxRadioBox which inherited the wrong class, thanks Atilla Erdodi.
