Saw the announcement that there were fixes as well as new features. I was disappointed that the Scripting text size bug introduced in 2014 was not fixed and nether was the new bug in the background erase tool. I do not know if the Photomerge bug was address I don't use Photomerge.
Photomerge has worked fine since 2014.2.0.
Apparently there were crash type bugs fixed in 2014.2.1, though I never saw any of them with 2014.2.0.
