  • v0.8.0 Changes

    April 12, 2018

    BACKWARDS INCOMPATIBILITIES:

    • cli: node drain now blocks until the drain completes and all allocations on the draining node have stopped. Use -detach for the old behavior.
    • client: Periods (.) are no longer replaced with underscores (_) in environment variables as many applications rely on periods in environment variable names. [GH-3760]
    • client/metrics: The key emitted for tracking a client's uptime has changed from "uptime" to "client.uptime". Users monitoring this metric will have to switch to the new key name [GH-4128]

    • drain: Draining a node no longer stops all allocations immediately: a new migrate stanza allows jobs to specify how quickly task groups can be drained. A -force option can be used to emulate the old drain behavior.
    • jobspec: The default values for restart policy have changed. Restart policy mode defaults to "fail" and the attempts/time interval values have been changed to enable faster server side rescheduling. See restart stanza for more information.
    • jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update stanza syntax. All job spec files should be using update stanza fields introduced in 0.7.0 [GH-3979]

  • v0.7.1 Changes

    December 19, 2017

    BACKWARDS INCOMPATIBILITIES:
