Own Id: OTP-11586

Some local implementations of removing the last element from a list are replaced by lists:droplast/1. Note that this requires at least stdlib-2.0, which is the stdlib version delivered in OTP 17.0. (Thanks to Hans Svensson)

Own Id: OTP-11678

Reworked the internal event handling to avoid crashes in destroy objects. Thanks Tom for the bug report.

Own Id: OTP-11699

asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

(Thanks to Tobias Schlager)

Own Id: OTP-11744

## Wx 1.1.2

### Fixed Bugs and Malfunctions

Own Id: OTP-11515

## Wx 1.0

Add {silent_start, boolean()} option to wx:new/1 in order to be able to suppress error messages during startup of wx. (Thanks to Håkan Mattsson)

Own Id: OTP-10585

Fix wxTreeCtrl:getBoundingRect/2 and wxTreeCtrl:hitTest/1. wxTreeCtrl:hitTest 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-10407 Aux Id: kunagi-262 [173]

## Wx 0.99.2

### Improvements and New Features

Fix errors in wxDC and wxGraphicsContext api.

## Wx 0.98.8

### Improvements and New Features

Fix an external loop when stopping erlang nicely.

Separate OpenGL to it's own dynamic loaded library, so other graphic libraries can reuse the gl module and it will not waste memory if not used.

Own Id: OTP-8408

Cleanups suggested by tidier and modernization of types and specs.

Calling non supported wxWidgets functions hanged instead of crashed.

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