@merlin-northern, Let me know if you want to start the integration pipeline by mentioning me and the command "start pipeline".

---

my commands and options

You can trigger a pipeline on multiple prs with:

• mentioning me and start pipeline --pr mender/127 --pr mender-connect/255

You can cherry pick to a given branch or branches with:

• mentioning me and:

 cherry-pick to:
 * 1.0.x
 * 2.0.x
