2.0.3

New

• Added an optional system.session.read_and_close setting that releases the session as soon as it has been read, so a site's simultaneous requests no longer queue up one behind another waiting on the session; off by default.

Bugfix

• A bin/gpm self-upgrade that stops while replacing core files now names the exact file or folder it could not remove and the reason why, and points out when the file is owned by a different user than the one running the command, which is the usual cause of an upgrade that works from the admin but fails on the command line. Fixes #4162.
