 - DrawList: Fixed PathArcTo() emitting terminating vertices too close to arc vertices. (#4993) [@thedmd]
 - DrawList: Fixed texture-based anti-aliasing path with RGBA textures (#5132, #3245) [@cfillion]
 - DrawList: Fixed divide-by-zero or glitches with Radius/Rounding values close to zero. (#5249, #5293, #3491)
+- DrawList: Circle with a radius smaller than 0.5f won't appear, to be consistent with other primitives. [@thedmd]
 - Debug: Added DebugTextEncoding() function to facilitate diagnosing issues when not sure about whether
   you have a UTF-8 text encoding issue or a font loading issue. [@LaMarche05, @ocornut]
 - Metrics: Added a "UTF-8 Encoding Viewer" section using the aforementioned DebugTextEncoding() function.
