Important: After committing and tagging the release, it turned out that our build system does not like the version tag. As such, builds are broken until we release a second release candidate. Sorry for the inconvenience.

The SuperTux team is excited to announce the availability of the first release candidate for the upcoming stable release 0.5.0 after less than a year of development. The most prominent change for this release is a new in-game level editor which allows you to create levels and worldmaps on-the-fly from within SuperTux itself. No need for installing an external editor, anymore. Since this editor is still very much work-in-progress, we'd like to ask you to test it thoroughly. The chances are high that we missed some bugs during our initial testing rounds.

Testing this release candidate will help us avoiding a large amount of issues reported for stable release, as occurred with the v0.4.0 release. We would like to apologize for those problems. Please report any problem you might encounter on GitHub and please follow the bug reporting guidelines.

Changes:

• In-game level editor
• Improved levels in Antarctica and Forest Island
• Language packs are fixed
• Engine performance improvements
• Extended the scripting API: gradients are now scriptable
• Added a few more tiles and music
• New console commands and command line options (related to the editor)
• Various other bugfixes of issues reported since the v0.4.0 release

Thanks to @Hume2 for large parts of the editor code. Other contributions were made by @tobbi and @Karkus476.

The improved Forest Island levels are part of larger project aiming to redesign the Forest Island. A more finished up version of Forest Island should be included in a future release. Until then, Forest Island will remain in development and stay open for suggestions as mentioned in the v0.4.0 release announcement. Feedback can be posted at http://forum.freegamedev.net/viewtopic.php?f=67&t=7098 and https://github.com/SuperTux/data/issues/28. Thanks to @Rusty-Box and @serano01 for working on the levels.
