 Other Changes:
 
+- Window: Fixed using non-zero pivot in SetNextWindowPos() when the window is collapsed. (#3433)
+- Nav: Fixed navigation resuming on first visible item when using gamepad. [@rokups]
+- Nav: Fixed using Alt to toggle the Menu layer when inside a Modal window. (#787)
 - InputText: Added selection helpers in ImGuiInputTextCallbackData().
 - InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit.
   (note that InputText() already returns true on edit, the callback is useful mainly to manipulate the
   underlying buffer while focus is active).
+- InputText: Fixed using ImGuiInputTextFlags_Password with InputTextMultiline(). (#3427, #3428)
+  It is a rather unusual or useless combination of features but no reason it shouldn't work!
 - DragFloat, DragScalar: Fixed ImGuiSliderFlags_ClampOnInput not being honored in the special case
   where v_min == v_max. (#3361)
 - BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(),
   so e.g. calling the function at the end of a window would often add +ItemSpacing.y to scrolling range.
-- TreeNode, CollapsingHeader: Made clicking on arrow toggle toggle the open state on the Mouse Down event 
-  rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior 
-  and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.

   (This is also necessary to support full multi/range-select/drag and drop operations.)
 - Tab Bar: Keep tab item close button visible while dragging a tab (independent of hovering state).
+- Tab Bar: Fixed a small bug where toggling a tab bar from Reorderable to not Reorderable would leave
+  tabs reordered in the tab list popup. [@Xipiryon]
 - Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
 - Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
 - Examples: Vulkan: Reworked buffer resize handling, fix for Linux/X11. (#3390, #2626) [@RoryO]

     - You can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert
       and get a _similar_ effect as previous uses of power >1.0f.
   See https://github.com/ocornut/imgui/issues/3361 for all details.
+  For shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
   Kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar().
   For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
