Is there no more auto_pause_resume or on_fail in prefect2? I don't use prefect cloud, is there an alternative? Also, should we avoid installing 1.* for new installations?

you can build automation to pause the deployment's schedule if a given run fails - this is cloud feature, so in OSS, you'd need to build it by checking the final state and making API request to pause schedule of the deployment id inferred from context (did you know Cloud is free to use though? not a trial) spot on, install v2

THANKS!
