Does anyone here know if the Bug 345589 (received iCal updates do not remove
old versions of the item) and Bug 345591 (received iCal cancels do not
remove the item from the GroupWise calendar) have been fixed in Groupwise

Here is a brief description of the bug:

If the originator issues and update, the update is not reconciled with the
original meeting but adds a new meeting which is usually in time overlap
with the original. Manually deleting the obsolete one later sends a
"Decline" to the originator, confusing them.
