docs/CHANGELOG.txt
View File

@ -55,6 +55,8 @@ Breaking Changes:
- Renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges and removed its [Beta] mark.
The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names.
- Made it illegal to call Begin("") with an empty string. This somehow accidentally worked before but had various
undesirable side-effect as the window would have ID zero. In particular it is causing problems in viewport/docking branches.
Other Changes:
- Added BETA api for Tab Bar/Tabs widgets: (#261, #351)
