• Plugin and theme update notifications (on their respective admin pages)
  • you can manually set back version numbers if needed
  • config.ini setting versionNotifications set to false should disable the notifications
• Tag browse for items should sort alphabetical by default (this is the browse accessible from public item browse pages, not the Tags browse in the admin)
• New config.ini settings mail.force_from and mail.force_from_name: make all outgoing mail originate from the given address (and optionally the given "friendly" name), useful for situations where your server can only send mail from a particular address or domain (required by some cloud hosts, and often necessary to have mail actually successfully delivered)
• New config.ini setting sslTrustProxy: if the ssl setting is enabled, whether to trust the contents of the "X-Forwarded-Proto" HTTP header (useful if you want to use the ssl setting but are hosting Omeka behind a proxy server)

Update notifications only display on a theme when it's active; themes not in use as the primary theme have no indication of status.
