 Breaking Changes:
 
+ - Combo(), ListBox(): commented out legacy signatures which were obsoleted in 1.90
+   (Nov 2023), when the getter callback type was changed from:
+      getter type:   bool (*getter)(void* user_data, int idx, const char** out_text)
+   To:
+      getter type:   const char* (*getter)(void* user_data, int idx)
+
 Other Changes:
 
 - Style: border sizes are now scaled (and rounded) by ScaleAllSizes().

+ - 2026/02/27 (1.92.7) - Commented out legacy signature for Combo(), ListBox(), signatures which were obsoleted in 1.90 (Nov 2023), when the getter callback type was changed.
+                         - Old getter type:   bool (*getter)(void* user_data, int idx, const char** out_text)   // Set label + return bool. False replaced label with placeholder.
+                         - New getter type:   const char* (*getter)(void* user_data, int idx)                   // Return label or NULL/empty label if missing
  - 2026/01/08 (1.92.6) - Commented out legacy names obsoleted in 1.90 (Sept 2023): 'BeginChildFrame()' --> 'BeginChild()' with 'ImGuiChildFlags_FrameStyle'. 'EndChildFrame()' --> 'EndChild()'. 'ShowStackToolWindow()' --> 'ShowIDStackToolWindow()'. 'IM_OFFSETOF()' --> 'offsetof()'.
  - 2026/01/07 (1.92.6) - Popups: changed compile-time 'ImGuiPopupFlags popup_flags = 1' default value to be '= 0' for BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick(). Default value has same meaning before and after.
