Work in Progress

Expected features

• highly modularized code extensively using Trac's component architecture
• intelligent event filtering bringing together classic function (ticket-cc), general settings (always_cc in trac.ini) and user settings (current ​AnnouncerPlugin opt-in and opt-out)
• keep option names interchangeable with Trac Notification for ease of migration
• make minimal required set of options smaller than now, if possible
• keep interface to ​WatchlistPlugin as nice, readable user subscription summary page
• maintain attractive ExtensionPoint to actively support easy creation of more transports like done with ​FullBlogPlugin
• add support for cryptographically signed/encrypted announcements
