Changes
== Beta 23 ==
Bugfixes:
* A nasty error ("collection modified") that happened now and then in many situations was fixed.
Changes:
* Models from unknown ources are marked as "changed" by default in order to indicate that they're most likely not yet persisted in the project nor in the environment.
== Beta 22 ==
Known Problems:
* Sometimes, an error message "Collection modified, enumeration operation may not execute" appears and stops an ongoing action. We're working on it.
== Beta 21 ==
Known Problems:
* Connections aren't shown correctly sometimes (invisible or wrong positions) - we're working on it.
