open-nomad/CHANGELOG.md

0.3.1 (UNRELEASED)

BACKWARDS INCOMPATIBILITIES:

• jobspec: Require RFC-1123 and RFC-2782 valid service names [GH-915]

IMPROVEMENTS:

• cli: Validate job file schemas [GH-900]

• driver/docker: Periodic Fingerprinting [GH-893]
• driver/docker: Preventing port reservation for log collection on Unix platforms [GH-897]
• driver/rkt: Pass DNS information to rkt driver [GH-892]

BUG FIXES:

• core: No longer cancel evaluations that are delayed in the plan queue [GH-884]
• api: Guard client/fs/ APIs from being accessed on a non-client node [GH-890]
• client: Allow dashes in variable names during interprelation [GH-857]
• client: Updating kill timeout adheres to operator specified maximum value [GH-878]

0.3.0

BACKWARDS INCOMPATIBILITIES:

• Stdout and Stderr log files of tasks have moved from task/local to alloc/logs [GH-851]
• Any users of the runtime environment variable $NOMAD_PORT_ will need to update to the new ${NOMAD_ADDR_} varriable [GH-704]
