This means, that as of Contrexx 3.2 it is possible to access Contrexx twice at the same time without any session variable getting lost. In Contrexx 3.1 the whole session has been written in one database field, there was no merging process.

In version 3.2 there is a useful database caching for doctrine entities. As soon as a query gets built through the entity manager, database caching is activated if the system is configured like this. There are new configurations in General configurations > Caching section. You have to explicitly deactivate the caching if you don't want to load cached entities.
