So far one of my app was running on 1.2.0.6311 version released on 2 Jan 2008. It worked fine, and newer version could break something, so I didn’t bother to upgrade. However now, when new functionalities are to be implemented, I finally decided to migrate (to 1.2.0.7296 RC2). Of course some things stopped working as I expected, so I decided to list them here for others.

• custom validation methods defined in a model must be public now
• App::Import changed again, so my post about switching from vendors() to App::Import from March 2008 is not actual anymore
• structure of core.php file was changed a little, so configuring the file from scratch would be a good idea
• some ‘deprecated’ warnings, easy to correct

Well that is not much, even for such a quite simple application. Honestly, I expected to face more problems. Hopefully they don’t remain undiscovered.
