+ - 2025/12/23 (1.92.6) - Fonts:AddFontDefault() now automatically selects an embedded font between the new scalable AddFontDefaultVector() and the classic pixel-clean AddFontDefaultBitmap().
+                         The default selection is based on (style.FontSizeBase * FontScaleMain * FontScaleDpi) reaching a small threshold. Prefer calling either based on your own logic. You can call AddFontDefaultBitmap() to ensure legacy behavior.
+ - 2025/12/23 (1.92.6) - Fonts: removed ImFontConfig::PixelSnapV added in 1.92 which turns out is unnecessary (and misdocumented). Post-rescale GlyphOffset is always rounded.
  - 2025/12/17 (1.92.6) - Renamed helper macro IM_ARRAYSIZE() -> IM_COUNTOF(). Kept redirection/legacy name for now.
  - 2025/12/11 (1.92.6) - Hashing: handling of "###" operator to reset to seed within a string identifier doesn't include the "###" characters in the output hash anymore.

  - 2025/11/24 (1.92.6) - Fonts: Fixed handling of `ImFontConfig::FontDataOwnedByAtlas = false` which did erroneously make a copy of the font data, essentially defeating the purpose of this flag and wasting memory.
                          (trivia: undetected since July 2015, this is perhaps the oldest bug in Dear ImGui history, albeit for a rarely used feature, see #9086)
                          HOWEVER, fixing this bug is likely to surface bugs in user code using `FontDataOwnedByAtlas = false`.
