||||
- InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787)
|
||||
- Examples: GLFW: Made it possible to Shutdown/Init the backend again (by reseting the time storage properly). (#1827) [@ice1000]
|

- Misc: Updated stb_textedit from 1.09 + patches to 1.12 + minor patches.
|
