Upgrading Notes

1. v1.5 is not fully backward compatible with old version as some deprecated fields are removed, please check Major Changes, and use the new approaches recommended if you are using any of those deprecated fields.
2. If your Trigger has multiple dependencies, for example A && B, upgrading from previous version should be conducted after an action is triggered, before a new event from either A or B is emitted. Otherwise the new emitted event will be ignored.

Major Changes

• Trigger rate limiting - enabling guard rails for protecting downstream service resource starvation.
• Support Bitbucket event source.
• Support Pulsar trigger.
• Gitlab event source to support multiple projects.
• Simplified Workflows & k8s resources creation - group/version/kind not needed any more.
• Following deprecated fields are removed (notified in v1.3).

1. caCertPath, clientCertPath and clientKeyPath for tlsConfig in EventSources and Sensor are removed, use caCertSecret, caCertSecret and clientKeySecret instead.
2. spec.nats.native.antiAffinity in EventBus is removed, use spec.nats.native.affinity instead.
3. userPayload in CalendarEventSource is unsupported, use metadata instead.
4. credentialsFile in PubSubEventSource is unsupported , use credentialSecret instead.
5. serverCertPath and serverKeyPath for webhook typed EventSource are removed, use serverCertSecret and serverKeySecret instead.
6. circuit, switch and dependencyGroups are not supported any more, use Trigger Conditions instead.
7. certFilePath in CustomTrigger spec is unsupported, use certSecret instead.
8. When configuring trigger source with git, sshKeyPath is unsupported, use sshKeySecret instead.
9. spec.replica is removed in EventSource object, use spec.replicas.
