Version 21.12.1

• #2349 Only display MOTD on startup

Version 21.12.0

Features

• #2260 Allow early Blueprint registrations to still apply later added objects
• #2262 Noisy exceptions - force logging of all exceptions
• #2264 Optional uvloop by configuration
• #2270 Vhost support using multiple TLS certificates
• #2277 Change signal routing for increased consistency
  • BREAKING CHANGE: If you were manually routing signals there is a breaking change. The signal router's get is no longer 100% determinative. There is now an additional step to loop thru the returned signals for proper matching on the requirements. If signals are being dispatched using app.dispatch or bp.dispatch, there is no change.
