@ -207,6 +207,7 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
- tree node: tweak color scheme to distinguish headers from selected tree node (#581)
- tree node: leaf/non-leaf highlight mismatch.
- tree node: _NoIndentOnOpen flag? would require to store a per-depth bit mask to store info for pop (or whatever is cheaper)
- settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)

- 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
- 2018/06/08 (1.62) - examples: the imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.).
old binding will still work as is, however prefer using the separated bindings as they will be updated to be multi-viewport conformant.
old bindings will still work as is, however prefer using the separated bindings as they will be updated to support multi-viewports.
when adopting new bindings follow the main.cpp code of your preferred examples/ folder to know which functions to call.
in particular, note that old bindings called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
- 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
- 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
- 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
