Internals: Settings: Simple optimization caching index into the settings buffer, to remove an unnecessary O(N*M) search during saving. (with N=active root windows during the session, M=stored settings which grows over time)

Allow menu windows from ignoring the style.WindowMinSize values so short menus are not padded. (#1909)

Double-click on resize grip doesn't need to test HoveredWindow (as button has the flattenchild flag anyway) + double-click on title bar verify that we don't have overlapping items to allow contents in title bar. + Comments

Internals: Various renaming. e.g. NewFrameUpdateHoveredWindowAndCaptureFlags() to UpdateHoveredWindowAndCaptureFlags() + exposed UpdateMovingWindow() in imgui_internal.h.

ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat). Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.

Internals: Moved some of the SliderBehaviorT code into SliderBehavior to reduce the amount of instanciated code.

Version 1.63 WIP

Version 1.62

Fixed warnings + readme

Added assert in TreePop() to ease catching ID stack underflow earlier.

Revert 640c0566: TreeNode: Fixed nodes with ImGuiTreeNodeFlags_Leaf flag always returning true which was meaningless -> more flexible to keep allowing it by default so it setup an ID scope.

Added _None values to various enum flags, useful for readability and some coding style likes it. (Unfortunately we can't refer to them as default value in imgui.h functions because they need to be declared below).

Speculative fix for Win32 clipboard handler if SetClipboardText() fails + Minor fix for static analyzer + using :: prefix when calling in Win32 functions.

Added IsItemDeactivatedAfterChange() if the last item was active previously, isn't anymore, and during its active state modified a value. Note that you may still get false positive. (#820, #956, #1875)

Internals: Added GetItemID(), GetFocusID() for consistency. Made GetActiveID() inline. Comments, fixed typos, demo tweaks.

Added IsItemDeactivated() to query if the last item was active previously but isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875)

Comments

Comments, documentation

Big example binding refactor (manually imported from Viewport branch, stripped out of Viewport code). (#1870) ...

Read examples/README.txt for some details.
ImDrawData: Added DisplayPos, DisplaySize fields honored by all backends (not strictly necessary to honor just now, but doing it to be ahead)

Nav: Addendum: only set io.WantSetMousePos if necessary. (#1867)

Nav: Removed an unnecessary assertion that could fail when using Mouse and Keyboard simultaneously with the NavEnableSetMousePos flag. (#1867)

SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866)

Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not fully close/re-open the popup so its child popups won't get closed. (#1497, #1533, #1865). ...

Followup/fix the change made in deab2ab

Readme, FAQ tweaks (#1807)

Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese characters. Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. (#1859) ...

Changed the accumulative encoding to remove the implicit +1 which only saved a little space and made things more confusing.

TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen. The flag was already set by CollapsingHeader(). The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without ImGuiTreeNodeFlags_NoTreePushOnOpen. In which case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864)

InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787)

Nav: Fixed clipped scoring when exiting a NavFlattened child back to a parent item (clipping not desirable then). (followup and fix to c665c15). (#787)

Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787)

Changelog formatting update, Todo, comments. Tweak Child demo. Shuffle some code in NavUpdate().
