Consul - v1.18.0-rc1

1.18.0-rc1 (February 6, 2024)

BREAKING CHANGES:

• 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]
