Added PushID(size_t sz) helper (may not be useful/meaningful for non C/C++ languages).

Update README.md (changed e-mail address)

Reoder Python bindings

When resizing from an edge, the border is more visible and better follow the rounded corners. Border rendering moved to RenderOuterBorders so it can be called in a different order for docking. (#1495, #822)

Fixed range-version of PushID() and GetID() not honoring the ### operator to restart from the seed value.

Fixed using imgui_freetype.cpp in unity builds. (#2302)

Removed trailing spaces from text files. (#2038, #2299)

ImGuiTextBuffer: Added append() function (unformatted).

Fix the year for screenshot gallery part 7 and 8 links (#2298)

Qt links

Examples: Win32: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages. (#2264)

ImFontAtlas: Added 0x2000-0x206F general punctuation range to default ChineseFull/ChineseSimplifiedCommon ranges. (#2093)

Examples: Win32: Using IsChild() to be compatible with windows created within a parent. (#1951, #2087, #2156, #2232)

Examples: DirectX9: Explicitly disable fog (D3DRS_FOGENABLE) before drawing in case user state has it set. (#2288, #2290)

EditorConfig: Further tweaks (#2038)

ImDrawList: Fixed AddCircle(), AddCircleFilled() angle step being off, which was visible when drawing a "circle" with a small number of segments (e.g. an hexagon). (#2287) [@baktery] ...

+ Demo tweaks

FreeType: Minor tweaks previous commit (#2285)

Examples: Win32: Added support for XInput games (if ImGuiConfigFlags_NavEnableGamepad is enabled).

Examples: Win32: Using GetForegroundWindow() instead of GetActiveWindow() to be compatible with windows created in a different thread. (#1951, #2087, #2156, #2232) [many people]

Version 1.68 WIP

TODO update + internals: changed order or ImGuiLayoutType enums to allow using them for indexing.

Version 1.67

DragFloat: Fixed broken mouse direction change with power!=1.0. (#2174, #2206) [@Joshhua5]

Merge branch 'atlas_fixes'

FAQ entry, moved ImTextureId, Gallery links.

ImFontAtlas: Rewrote FreeType based builder. ...

- Fixed abnormally high atlas height. (#618)
- Fixed support for any values of TexGlyphPadding (not just only 1). (#618)
- Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth). (#618)
- Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233, #618)
- Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas. (#618)

ImFontAtlas: Rewrote stb_truetype based builder. ...

- Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth).
- Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233)
- Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas.

ImFontGlyphRangesBuilder: Using 32-bits fields for storage instead of 8-bit ones, comments, todo.

Update link to Magnum bindings. (#2269) ...

The various community projects that integrated Dear ImGui into Magnum
were merged together and are now an official part of the engine.

ImDrawList: Optimized some of the functions for performance of debug builds where non-inline function call cost are non-negligible.
