   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)
 - DragFloat: Disabled setting a default drag speed when one edge is FLT_MAX. (#2024)
+- SliderAngle: Added optional format argument to alter precision or localize the string. (#2150) [@podsvirov]
 - Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
   of root floating windows outside the window, making it easier to resize windows. Resize grips are also
   extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
