v0.6.33

• Updated to the latest version of cron-utils 9.0.0 and removed threeten-backport. This fixes a number of cron related issues in the underlying dependencies.
• When querying run detail with embed=history, successfulFinishedRuns and failedFinishedRuns contains new field tasks which is an array of taskIds of that finished run. This will allow people to query task ids even for finished job runs.
• Fixed a bug when task status was not updated after the task turned running (when querying embed=activeRuns).
• DCOS_OSS-5166 Fixed metronome not using revive operation

Command line parameters

Command line parameter task.lost.expunge.gc was removed because the underlying algorithm change and this
one no longer has any effect.

Metrics

We moved to a different Metrics library and the metrics are not always compatible or the same as existing metrics;
however, the metrics are also now more accurate, use less memory, and are expected to get better throughout the release.
Where it was possible, we maintained the original metric names/groupings/etc, but some are in new locations or have
slightly different semantics. Any monitoring dashboards should be updated.

For Metronome specific metrics, you can find your old metrics under in the same path, only prefixed with "service"
so e.g. 'dcos.metronome.jobspec.impl.JobSpecServiceActor.receiveTimer' is now
'service.dcos.metronome.jobspec.impl.JobSpecServiceActor.receiveTimer'.

The format of the v1/metrics endpoint also changed in a backward incompatible manner - please see the documentation
for the current way the metrics are served.
