v2.9.1

Changed

• Speed up pack registration through the /v1/packs/register API endpoint. (improvement) #4342
• Triggertypes API now sorts by trigger ref by default. st2 trigger list will now show a sorted list. (#4348)
• Update st2-self-check script to include per-test timing information. (improvement) #4359

Fixed

• Update st2sensorcontainer service to throw if user wants to run a sensor from a pack which is using Python 3 virtual environment. We only support running Python runner actions from packs which use mixed Python environments (StackStorm components are running under Python 2 and particular a pack virtual environment is using Python 3). #4354
• Update st2-pack-install and st2 pack install command so it works with local git repos (file://) which are in a detached head state (e.g. specific revision is checked out). (improvement) #4366
• Fix a race which occurs when there are multiple concurrent requests to resume a workflow. #4369
