A couple of weeks after the release of Hotfix Package 4 for Microsoft Application Virtualization 5.0 SP2, a new hotfix pack has been released.
More information can be found at http://support.microsoft.com/kb/2963211/en-gb.
A summary of the changes:
Issue 1: Connection groups cannot support both user-published and global-published packages
App-V 5.0 SP2 does not let you create user-entitled connection groups that contain both user-published and global-published packages.
With this hotfix release, App-V 5.0 SP2 supports creating user-entitled connection groups that contain user-published and global-published packages by using Windows PowerShell.
[notice]Note Connection groups that contain user and global packages are currently not supported through the App-V server.[/notice]
Issue 2: Enabling user-publishing in the Administrator context through Windows PowerShell
This hotfix release enables user-publishing to be done in the Administrator context through PowerShell cmdlets.
Issue 3: Deprecation of PackageStoreAccessControl support in App-V 5.0 SP2
Effective immediately, the PackageStoreAccessControl (PSAC) setting that was introduced in App-V 5.0 SP2 is being deprecated in both single-user and multiuser environments.
The PSAC setting has been unsupported in multiuser environments since the first hotfix package for App-V 5.0 SP2, but PSAC deployment in single-user environments was supported until now. If you deployed PSAC to single-user environments, remove the configuration option from any deployments.
