In the deployment system, we now have ModuleBuilderExtensions to  
(javaee) ModuleBuilders that greatly simplify dealing with "extension  
specs" such as jsp and jsf (to pick a couple examples I've dealt with  

In the security system, I've made it so all Subjects come from  
logging into a security realm.  Previously we were constructing  
subjects for defaults and run-as in a limited and ad-hoc way.  I'm  
working on simplifying the security system quite a bit including  
removing the remote login module capability.  It's only use was for  
openejb clients and this will be running over the openejb protocol  
very very soon.

In a minor structural change the way resource managers register with  
the transaction manager for recovery is now somewhat simpler and  
easier to follow.

I'm never sure what "architectural" means but these are what come to  
mind as possible related to architecture.
