Adobe have historically released a 0.1 release of most versions of Photoshop over the years so it was unusual to see a 0.2 release some time ago. Today Adobe release a 0.3 update bringing the total to 3.
To be fair most of the bugs look pretty obscure and I have not noticed many of them myself. All the fixes seem to be platform dependant (fonts etc) so this release is just for Windows systems.
If you dont get updated automatically then select from the “Help” menu the subitem “Updates…”
You can check your version of Photoshop by selecting the “Help” menu and choosing “About Photoshop…”
