Hi everyone,

 

We are pleased to announce the release candidate for HashiCorp Nomad 0.9.4. This includes a number of fixes for cluster stability, usability, and performance, including:

  • agent: Multiple issues around client/server restarts [GH-5837,GH-5890,GH-5906]

  • core: Deregister nodes in batches rather than one at a time [GH-5784]

  • core: System jobs that fail because of resource availability are retried when resources are freed [GH-5900]

  • core: Ensure plans are evaluated against a new enough snapshot index [GH-5791]

  • core: Handle error case when attempting to stop a non-existent allocation [GH-5865]

  • core: Fixed a bug where nomad log and exec requests may time out or fail in tls enabled clusters [GH-5954].

  • client: Improved task event display message to include kill time out [GH-5943]

  • client: Fixed regression that prevented registering multiple services with the same name but different ports in Consul correctly [GH-5829]

  • client: Fixed a race condition when performing local task restarts that would result in incorrect task not found errors on Windows [GH-5899]

  • client: Reduce CPU usage on clients running many tasks on Linux [GH-5951]

  • driver/docker: Added logging defaults to use json-file log driver with log rotation [GH-5846]

  • driver: Fixed an issue preventing local task restarts on Windows [GH-5864]

  • driver: Fixed an issue preventing external driver plugins from launching executor process [GH-5726]

  • driver/docker: Fixed a bug mounting relative paths on Windows [GH-5811]

  • metrics: Added namespace label as appropriate to metrics [GH-5847]
