We've been working on some exciting P updates that we're looking forward to announcing 🔜. In the meantime, our team and community members have squashed 🐛 and made incremental enhancements in last week's 0.15.5 Release. Here are some highlights: • Python 3.9 support is stabilizing and we are now publishing Docker images e.g.

0.15.5-python3.9

. • While registering very large flows, it was possible to see timeouts or incomplete registration. Now, flow edges and tasks are registered in batches allowing for much larger flows. • Agentless flow runs now receive the environment variables of the process that starts them; this makes agentless runs easier to use in production. •

--idempotency-key

support has been added to

prefect run

•

prefect run

will now ignore schedules on local flow runs by default and only a single run will be performed. A

--schedule

flag was added if you’d like the command to go forever and run the flow on a schedule. • Several task library improvements have been made, including a new

SnowflakeQueryFromFile

task, improved logging in the AWS

BatchSubmit

task, improved runtime handling for MySQL Tasks, and updated authentication for the

DremioFetch

task. • Log limits have been updated to reduce errors when many large logs are sent. Note that this release includes several breaking changes: • In a secure-by-default effort, services run by the

prefect server

cli now listen to localhost by default and are not accessible from other machines; use

--expose

to allow connections from a remote location. • Prefect Server will need to be upgraded to version

2021.09.02

before flows can be registered from this version of Core. Special thanks to Deepyaman Datta, Henri Hannetel, Johnny Tirado, @Kathryn Klarich, @Tenzin Choedak, and Vincent Xue for contributing to this release 🙏!
