@ -68,9 +68,10 @@ Other Changes:
- InputText: Fixed updating cursor/selection position when a callback altered the buffer in a way
where the byte count is unchanged but the decoded character count changes. (#3587) [@gqw]
- Metrics: Fixed mishandling of ImDrawCmd::VtxOffset in wireframe mesh renderer.
- Misc: Replaced UTF-8 decoder by branchless one by Christopher Wellons (30~40% faster). [@rokups]
- Misc: Replaced UTF-8 decoder with one based on branchless one by Christopher Wellons. [@rokups]
Super minor fix handling incomplete UTF-8 contents: if input does not contain enough bytes, decoder
returns IM_UNICODE_CODEPOINT_INVALID and consume remaining bytes (vs old decoded consumed only 1 byte).
- Misc: Fix format warnings when using gnu printf extensions in a setup that supports them (gcc/mingw). (#3592)
- Misc: Made EndFrame() assertion for key modifiers being unchanged during the frame (added in 1.76) more
lenient, allowing full mid-frame releases. This is to accommodate the use of mid-frame modal native
windows calls, which leads backends such as GLFW to send key clearing events on focus loss. (#3575)
