@ -105,12 +105,21 @@ Other Changes:
- Added .editorconfig file for text editors to standardize using spaces. (#2038) [@kudaba]
- InputText: Fixed a bug where ESCAPE would not restore the initial value in all situations. (#2321) [@relick]
- InputText: Fixed a bug where ESCAPE would be first captured by the Keyboard Navigation code. (#2321, #787)
- InputText: Fixed redo buffer exhaustion handling (rare) which could corrupt the undo character buffer. (#2333)
The way the redo/undo buffers work would have made it generally unnoticeable to the user.
- Added IsItemActivated() as an extension to the IsItemDeactivated/IsItemDeactivatedAfterEdit functions
which are useful to implement variety of undo patterns. (#820, #956, #1875)
- Fixed range-version of PushID() and GetID() not honoring the ### operator to restart from the seed value.
- Fixed CloseCurrentPopup() on a child-menu of a modal incorrectly closing the modal. (#2308)
- Tabs: Added ImGuiTabBarFlags_TabListPopupButton flag to show a popup button on manual tab bars. (#261, #351)
- Tabs: Removed ImGuiTabBarFlags_NoTabListPopupButton which was available in 1.67 but actually had zero use.
- Tabs: Fixed a minor clipping glitch when changing style's FramePadding from frame to frame.
- Menus: Tweaked horizontal overlap between parent and child menu (to help convey relative depth)
from using style.ItemSpacing.x to style.ItemInnerSpacing.x, the later being expected to be smaller. (#1086)
- RadioButton: Fixed label horizontal alignment to precisely match Checkbox().
- Window: When resizing from an edge, the border is more visible and better follow the rounded corners.
- ListBox: Better optimized when clipped / non-visible.
- InputTextMultiline: Better optimized when clipped / non-visible.
- 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]
- ImGuiTextBuffer: Added append() function (unformatted).

**Why the odd dual naming, "Dear ImGui" vs "ImGui"?**
The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.
The library started its life as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0 and had no particular expectation that it would taker off.

Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. This is designed for binding other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for third-party bindings to other languages.

Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com).
I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it.
