Photoshop 12.1 = Photoshop 12.0.4
What’s the difference between Photoshop CS5 and 5.5? Nothing besides subscription support. Here’s some concise clarification from Jeff Tranberry:
Photoshop CS5 (Version 12.1 – which comes as part of Creative Suite 5.5) and Photoshop CS5 (Version 12.0.4 – a free update for the version of Photoshop which came as a part of Creative Suite 5) are exactly the same in terms of functionality except that 12.1 will support a subscription license.
