@ -37,6 +37,8 @@ HOW TO UPDATE?
Other Changes:
- TabBar: Fixed using more than 32 KB-worth of tab names. (#4176)
- Tables: Added ImGuiTableColumnFlags_NoHeaderLabel to request TableHeadersRow() to not submit label for a column.
Convenient for some small columns. Name will still appear in context menu. (#4206).
- Fixed printf-style format checks on non-MinGW flavors. (#4183, #3592)
- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
