- Fixed a single-axis auto-resizing feedback loop issue with nested containers
and varying scrollbar visibility. (#9352)
- Detect and report error when calling End() instead of EndPopup() on a popup. (#9351)
- Child windows with only ImGuiChildFlags_AutoResizeY flag keep using the proportional
default ItemWidth. (#9355)
- Multi-Select:
- Fixed an issue using Multi-Select within a Table causing column width measurement to
be invalid when trailing column contents is not submitted in the last row. (#9341, #8250)
- Box-Select: fixed an issue using ImGuiMultiSelectFlags_BoxSelect2d mode, where
items out of view wouldn't be properly selected while scrolling while mouse cursor
is hovering outside of selection scope. (#7994, #1861, #6518)
- Box-Select: fixed an issue where items out of horizontal view would sometimes lead
to incorrect merging of sequential selection requests while also scrolling fast
enough to overlap multiple rows during a frame. (#7994, #1861, #6518)
- Box-Select: fixed an issue using ImGuiMultiSelectFlags_BoxSelect2d mode in a Table
while relying on the TableNextColumn() return value to perform coarse clipping. (#7994)
- Box-Select: disabled merging consecutive selection requests as we have no reliable
way of detecting if user has submitted all consecutives items without clipping gaps,
and ImGuiSelectionUserData is technically opaque storage. (#7994, #1861)
(we will probably bring this back as a minor optimization if we have a way to for
user to tell us ImGuiSelectionUserData are indices)
- Box-Select, Tables: fixed an issue when calling `BeginMultiSelect()` in a table
before layout has been locked (first row or headers row submitted). (#8250)
- Style:
- Fixed vertical scrollbar top coordinates when using thick borders on windows
with no title bar and no menu bar. (#9366)
- Fonts:
- imgui_freetype: add FreeType headers & compiled version in 'About Dear ImGui' details.
- Assert when using MergeMode with an explicit size over a target font with an implicit
size, as scale factor are likely erroneous. (#9361)
- Clipper:
- Improved error reporting when misusing the clipper inside a table (prioritize
reporting the common clipper error over a table sanity check assert). (#9350)
- Tweaked assert triggering when first item height measurement fails, and made it
a better recoverable error. (#9350)
- Misc:
- Minor optimization: reduce redudant label scanning in common widgets.
- Backends:
- Metal: avoid redundant vertex buffer bind in SetupRenderState, which leads
- Metal: avoid redundant vertex buffer bind in `SetupRenderState()`, which leads

- SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()`
helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value
and this breaks scaling border size. (#9369)

- window/id_stack: add e.g. window->GetIDFromPath() with support for leading / and ../ (#1390, #331) -> model from test engine.

- scrolling: forward mouse wheel scrolling to parent window when at the edge of scrolling limits? (useful for listbox,tables?)

- widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
- widgets: add always-allow-overlap mode. This should perhaps be the default? one problem is that highlight after mouse-wheel scrolling gets deferred, makes scrolling more flickery.
- widgets: start exposing PushItemFlag() and ImGuiItemFlags
- widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
- widgets: activate by identifier (trigger button, focus given id)
- widgets: custom glyph/shapes replacements for stock shapes. (also #6090 #2431 #2235 #6517)
- widgets: coloredit: keep reporting as active when picker is on?

- input text: preserve scrolling when unfocused?
- input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
- input text: expose CursorPos in char filter event (#816)
- input text: try usage idiom of using InputText with data only exposed through get/set accessors, without extraneous copy/alloc. (#3009)

- input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
- input text: hover tooltip could show unclamped text
- input text: support for INSERT key to toggle overwrite mode. currently disabled because stb_textedit behavior is unsatisfactory on multi-line. (#2863)
- input text: option to Tab after an Enter validation.
- input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
- input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
- input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
- input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it.
- input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
- input text: decorrelate display layout from inputs with custom template - e.g. what's the easiest way to implement a nice IP/Mac address input editor?
- input text: global callback system so user can plug in an expression evaluator easily. (#1691)
- input text: callback system (global) so user can plug in an expression evaluator easily. (#1691)
- input text: force scroll to end or scroll to a given line/contents (so user can implement a log or a search feature)
- input text: a way to preview completion (e.g. disabled text completing from the cursor)
- input text: a side bar that could e.g. preview where errors are. probably left to the user to draw but we'd need to give them the info there.
- input text: a way for the user to provide syntax coloring.
- input text: Shift+TAB with ImGuiInputTextFlags_AllowTabInput could eat preceding blanks, up to tab_count.
- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
- input text multi-line: support for copy/cut without selection (copy/cut current line?)
- input text multi-line: line numbers? status bar? (follow up on #200)
- input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
