@ -73,6 +73,7 @@ Other Changes:
accidental alteration of window position. We now round the provided size. (#2067)
- Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus
properly after the main menu bar or last focused window is deactivated.
- Nav: Fixed an assert in certain circumstance (mostly when using popups) when mouse positions stop being valid. (#2168)
- DragFloat: Fixed a situation where dragging with value rounding enabled or with a power curve
erroneously wrapped the value to one of the min/max edge. (#2024, #708, #320, #2075).
- DragFloat: Disabled using power curve when one edge is FLT_MAX (broken in 1.61). (#2024)
@ -105,7 +106,10 @@ Other Changes:
in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty.
- Examples: DirectX10, DirectX11: Removed seemingly unnecessary calls to invalidate and recreate device objects
in the WM_SIZE handler. (#2088) [@ice1000]
- Examples: GLFW: User previously installed GLFW callbacks are now saved and chain-called by the default callbacks. (#1759)
- Examples: OpenGL3: Added support for GL 4.5's glClipControl(GL_UPPER_LEFT). (#2186)
- Examples: OpenGL3+GLFW: Fixed error condition when using the GLAD loader. (#2157) [@blackball]
- Examples: OpenGL3+GLFW/SDL: Made main.cpp compile with IMGUI_IMPL_OPENGL_LOADER_CUSTOM (may be missing init). (#2178) [@doug-moen]

_NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_
