Local os x server mamp pro with php version 5.3.2 (tested php 5.2.13 too) with a fresh installation of Wordpress 3.1.1, doesn't show the latest version of the Gravity Forms Plugin on the plugins page.
I had the same problem with the beta version of GF 1.5 and Wordpress 3.0
Known issue or do you need my phpinfo file?
Thanks a lot!
