Release v0.22.0

Wednesday, December 01, 2021

Changelog since v0.21.1

New Features

Introduce trigger field to give more controls on triggering the deployment
- trigger.onCommit: controls triggering new deployment when newly added Git commits touched the application
- trigger.onCommand: controls triggering new deployment when received a new SYNC command from the web console or pipectl
- trigger.onOutOfSync: controls triggering new deployment when application is at OUT_OF_SYNC state. Enabling this will force Piped to always attempt to keep the application as synced as possible.
