Hi abv,

Now that it is no longer beta, is it possible to get more detailed information on the release? The Release Notes is surprisingly shorter than usual, so I cannot get much information about the new/changed classes/methods.

Many thanks,

Hello Nikolas,

Please check Upgrade Guide: it should describe all essential changes that need to be accounted for when porting from previous release. If you find some important change not described, please post an issue in Mantis.

For the detailed log of the changes made since previous version (previously contained in Release Note as long tables), you can parse Git log of the master branch between tags V7_4_0 and V7_3_0, for instance in GitWeb.
