Now that we're moving closer to the release, I think it makes sense

Packages should be all fine now. Please report any problems you may
have, I'm interested in getting them functioning reliably.
Associations are still a wound spot. I don't see when I will have the time
to implement the list view representation that you mention above.
The same goes for states and activities, which should be given a
representation in the model. Help is much appreciated.

Yes, code generation is still a problem.
At least we now can turn off undo/redo in the "Configure Umbrello" menu
which should already save significant memory.

I'm not quite sure I understand. Do you mean the popup should list
the available classifiers when creating attributes or operations?

I'm afraid that too will not make it into 1.3.
At least the C++ code import is now synced up with kdevelop.

How about making a bugs.kde.org entries for these?

Same here: Do we have a bugs.kde.org entry for this?

Yeah. Still in the realm of dreams unfortunately :)

Yes, it doesn't sound like something two or three hackers can do
in their spare time.

I hope to get the changes necessary for making the save format
of stereotypes and templates conform to the XMI standard into
umbrello in time for the 1.3 release. Of course there is still work left,
for example supporting multiplicities and tagged values in an XMI
standard conforming way, but that's not doable in the 1.3 timeframe.

I'm totally with you here. We are actually in desperate need of more help.
For one, I myself am far from being able to do the task justice in the
spare time that I have. -- Speaking of spare time, I'm on vacation
throughout the coming week.
