• Editor: Fixed issue where refresh timestamp in Package Manager/In Project view would not update correctly. (1254141)

• Editor: Fixing double consecutive OnDisable calls for inspectors while entering playmode or during assembly reload (1159201)

• Editor: Preset target has the Preset asset name in the Preset inspector instead of a blank name so custom inspector can always rely on the .target.name value to be the asset one. (1210891)

• Editor: prevents hang from calling capturescreenshotastexture() outside of playmode (1238552)

• Editor: Removed "macOS Color Picker" editor preference setting (that setting only ever partially worked anyway, e.g. it did not support HDR colors). (1231003)
