@ -9,6 +9,7 @@ Changes in ogl-es (not yet released - will be merged with trunk at some point)
--------------------------
Changes in 1.9 (not yet released)
- Add optional multitouch support to X11 (but disabled in IrrCompileConfig by default). Thanks @TheBrokenRail for a patch proposal based on example code from esjeon (patch #322).
- Slightly changed close window handling on X11 (optimized and avoids problems on some shells). Thanks @TheBrokenRail for a patch (was part of patch #322).
- Add getActiveColor functions to IGUIStaticText and IGUIButton (get currently used color).
- Add IGUIEnvironment::addToDeletionQueue to allow save removal of gui elements while iterating over them (like the same named function in ISceneManager).
