Bugs fixed (from release notes):
Sometimes 'p4 integrate' would find a distant base when
cherry picking revisions to integrate. Now 'p4 integrate'
insists that the base be the revision before the first
revision being integrated when cherry picking revisions.
'p4 submit' could report "No files to submit" if the
combination of client mapped files and protections table
exceeded an internal limit. This limit was incorrectly
reached on case-insensitive Servers (Windows) by repeated
values in a generated map. This has been fixed. (Bug #28853)
