Due to all development efforts being focused on expa3, there have been no significant updates on EXPA v2 in the last 2 months.
One change to note:
EXPA was not built to support a person managing more than 1024 objects (object = person, opportunity, branch) - when a person was managing more than 1024 objects, the system behaved unpredictably. To fix this, we started limiting one person to manage a max. of 1024 people. If you try to assign someone managing >= 1024 people as a manager, the system will not let you any more.
