Consul - v1.18.0



  • config-entries: Allow disabling request and idle timeouts with negative values in service router and service resolver config entries. [GH-19992]
  • telemetry: Adds fix to always use the value of telemetry.disable_hostname when determining whether to prefix gauge-type metrics with the hostname of the Consul agent. Previously, if only the default metric sink was enabled, this configuration was ignored and always treated as true, even though its default value is false. [GH-20312]



  • acl: add policy bindtype to binding rules. [GH-19499]
  • agent: Introduces a new agent config default_intention_policy to decouple the default intention behavior from ACLs [GH-20544]
  • agent: add fault injection filter support [GH-7513]
  • cloud: Adds new API/CLI to initiate and manage linking a Consul cluster to HCP Consul Central [GH-20312]
  • dns: adds experimental support for a refactored DNS server that is v1 and v2 Catalog compatible.
    Use v2dns in the experiments agent config to enable.
    It will automatically be enabled when using the resource-apis (Catalog v2) experiment.
    The new DNS implementation will be the default in Consul 1.19.
    See the Consul 1.18.x Release Notes for deprecated DNS features. [GH-20643]
  • ui: Added a banner to let users link their clusters to HCP [GH-20275]
  • ui: Adds a redirect and warning message around unavailable UI with V2 enabled [GH-20359]
  • ui: adds V2CatalogEnabled to config that is passed to the ui [GH-20353]

  • connect: Replace usage of deprecated Envoy fields envoy.config.route.v3.HeaderMatcher.safe_regex_match and envoy.type.matcher.v3.RegexMatcher.google_re2. [GH-20013]
  • docs: add Link API documentation [GH-20308]
  • resource: lowercase names enforced for v2 resources only. [GH-19218]


  • dns: SERVFAIL when resolving not found PTR records. [GH-20679]
