- Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143)
- Drag and Drop: Calling BeginTooltip() between a BeginDragSource()/EndDragSource() or BeginDropTarget()/EndDropTarget() uses adjusted tooltip
settings matching the one created when calling BeginDragSource() without the ImGuiDragDropFlags_SourceNoPreviewTooltip flag. (#143)
- IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211)
- Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut]
- Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
- Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)
- Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby]
- OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby]
- Demo: Added basic Drag and Drop demo. (#143)

- Examples: OpenGL3: Added shaders more versions of GLSL. (#1938, #1900, #1513, #1466, etc.)
- Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac.
- Examples: OpenGL3: Added error output when shaders fail to compile/link.
- Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor.
@@ -761,9 +765,9 @@ Other Changes:
- Clipboard: Added a void* user_data parameter to Clipboard function handlers. (#875) (BREAKING API)
- Internals: Refactor internal text alignment options to use ImVec2, removed ImGuiAlign. (#842, #222)
- Internals: Renamed ImLoadFileToMemory to ImFileLoadToMemory to be consistent with ImFileOpen + fix mismatching .h name. (#917)
- Windows: Fixed Windows default clipboard handler leaving its buffer unfreed on application's exit. (#714)
- Windows: No default IME handler when compiling for Windows using GCC. (#738)
