Version 1.66

Made IsWindowFocused() work outside of NewFrame()-EndFrame() and added comments about how ImGuiFocusedFlags_AnyWindow should NOT be used in place of io.WantCaptureMouse. (#2185)

SliderAngle: Added optional `format` argument to allow users customize precision and make localization. (#2150)

Misc comments improvements

Demo: Added comments / tweaks related to the popups.

Added ImGuiWindowFlags_NoMouseInputs which is basically the old ImGuiWindowFlags_NoInputs (essentially we have renamed ImGuiWindowFlags_NoInputs to ImGuiWindowFlags_NoMouseInputs). Made the new ImGuiWindowFlags_NoInputs encompass both NoMouseInputs+NoNav, which is consistent with its description. (#1660, #787)

Window: Added ImGuiWindowFlags_NoBackground flag for consistency and to ease creating new flag combinations. Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse. (#1660)

Fix Clang/GCC's null-conversion warning: (#2081) ...

The warning is "implicit conversion of NULL constant to 'unsigned int' [-Wnull-conversion]". Happens when ImTextureID is not a void*, but unsigned int, for example.

Renamed misc/stl/imgui_stl.h,.cpp to misc/cpp/imgui_stdlib.h in prevision for other files.(#2035, #2096) ...

Added misc/README file.

InputText: Clarified comments around ImGuiInputTextFlags_CallbackResize and other callbacks. (#2006, #1443, #1008)

ImGuiTextBuffer: Avoid heap allocation when empty.

Comments + internal using Tab Stop terminology (ImGuiItemFlags_NoTabStop instead of !ImGuiItemFlags_AllowKeyboardFocus)

Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143)

Fix missing IMGUI_API and mismatching namespace internal's CreateNewWindowSettings (#2105)

Renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).

BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack to the provided string to uniquely identify the child window. This was undoing an intentional change introduced in 1.50 and broken in 1.60. (#1698, #894, #713) + reworked the Begin/BeginChild comments in imgui.h.

ImVector: Fixed a oddly unqualified return type in the assignment operator (I assume C++ handles it nicely as this never warned anywhere, but it is completely unintentional).

Internals: Replace unsigned short with ImWchar when dealing with character storage. (#2078)

Version 1.66 WIP

Version 1.65

Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system. Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)

Renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + changed ImGuiIO layout.

Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent.

Minor mostly inconsequential merges from Viewport + LoadIniSettingsFromMemory() entirely skip lines starting with ';'

Version 1.65 WIP

Version 1.64

Version 1.64 WIP

Version 1.63

Reordered some declarations in imgui.h (in prevision of 1.64 refactor)

ImFontAtlas Comments (#2042) + added ImGuiFontAtlas_None for consistency.
