+ VERSION 1.90.8 (Released 2024-06-06)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.8
+
+Breaking changes:
+
+- Reordered various ImGuiInputTextFlags values. This should NOT be breaking unless
+  you are using generated headers that have values not matching the main library.
+- Removed ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft
+  from imgui.h, was mostly unused and misleading.
+
+Other changes:
+
+- Inputs: fixed IsMouseClicked(..., repeat=true); broken in 1.90.7 on 2024/05/22.
+  (due to an internal api parameter swap, repeat wouldn't be honored and
+  ownership would be accidentally checked even though this api is meant to not
+  check ownership). (#7657) [@korenkonder]
+- Windows: fixed altering FramePadding mid-frame not correctly affecting logic
+  responsible for honoring io.ConfigWindowsMoveFromTitleBarOnly. (#7576, #899)
+- Scrollbar: made scrolling logic more standard: clicking above or below the
+  grab scrolls by one page, holding mouse button repeats scrolling. (#7328, #150)
+- Scrollbar: fixed miscalculation of vertical scrollbar visibility when required
+  solely by the presence of an horizontal scrollbar. (#1574)
+- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_ParseEmptyRefVal
+  to parse an empty field as zero-value. (#7305) [@supermerill, @ocornut]
+- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_DisplayEmptyRefVal
+  to display a zero-value as empty. (#7305) [@supermerill, @ocornut]
+- Popups: fixed an issue preventing to close a popup opened over a modal by clicking
+  over void (it required clicking over the visible part of the modal). (#7654)
+- Tables: fixed an issue where ideal size reported to parent container wouldn't
+  correctly take account of inner scrollbar, affecting potential auto-resize of
+  parent container. (#7651)
+- Tables: fixed a bug where after disabling the ScrollY flag for a table,
+  previous scrollbar width would be accounted for. (#5920)
+- Combo: simplified Combo() API uses a list clipper (due to its api it wasn't
+  previously trivial before we added clipper.IncludeItemByIndex() function).
+- Disabled: nested tooltips or other non-child window within a BeginDisabled()
+  block disable the disabled state. (#211, #7640)
+- Misc: made ImGuiDir and ImGuiSortDirection stronger-typed enums.
+- Backends: SDL3: Update for SDL_SYSTEM_CURSOR_xxx api renames. (#7653)
