Singularity 0.4.2

This is a long overdue (~6 months) release -- apologies for the delay. Check out the 0.4.2 milestone to see new features / bugfixes in detail.

Important:

• Singularity now periodically cleans out old data from ZooKeeper. Singularity supports using MySQL as a persistence engine, and we suggest using it if retaining historical Request, Deploy, or Task data is important to you.

Deprecated:

• The .properties configuration format for Singularity slave helpers:

  • SingularityExecutor
  • SingularityExecutorCleanup
  • SingularityS3Downloader
  • SingularityS3Uploader
  • SingularityOOMKiller
  • SingularityLogWatcher

  If you use any of these, please convert your configuration to the .yaml style.

  .properties support will be removed completely in 0.4.5.
