Setup now allows specifying initial tempdb file size up to 256 GB (262,144 MB) per file, with a warning if the file size is set greater than 1GB with IFI not enabled.

Cross database transactions are now supported among all databases that are part of an Always On Availability Group, including databases that are part of same instance.
