v1.6.1

Compare Source

• Scheduler bugfix

v1.6.0

v1.6.0 brings:

• [scheduler] the notion of DAG runs allows for more parallelization, and controls around scheduling (max number of running task instance per DAG, max number of DAG runs to be evaluated for scheduling, ...)
• [scheduler] support for "externally triggered" DAG runs, or DAGs that run on demand as opposed to on a schedule
• [scheduler] support for cron-like syntax (as in: "0 0 * * *") and macros (as in "@​montlhly", "@​hourly", "@​weekly", ...)
• UI changes related to new scheduler features
• LDAP authentication for the web UI, more extensible authentication backend
• UI activity logging
• WebHdfsSensor and Hook for HDFS interactions that are py3 compatible
• Continuous integration with Travis-UI and Coveralls
• ShortCircuitOperator
• python3 compatibility!
• Tons of bug fixes and incremental improvements
• + all the things I'm forgetting while browsing through an infinite list of commits!

Thanks to everyone in the community for all the PRs (stellar contributions!), comments and issue reporting.
