1.10.0 (June 22, 2021)

BREAKING CHANGES:

• connect: Disallow wildcard as name for service-defaults. [GH-10069]
• connect: avoid encoding listener info in ingress and terminating gateway listener stats names. [GH-10404]
• licensing: (Enterprise Only) Consul Enterprise 1.10 has removed API driven licensing of servers in favor of license loading via configuration. The PUT and DELETE methods on the /v1/operator/license endpoint will now return 405s, the consul license put and consul license reset CLI commands have been removed and the LicensePut and LicenseReset methods in the API client have been altered to always return an error. [GH-10211]
• licensing: (Enterprise Only) Consul Enterprise client agents now require a valid non-anonymous ACL token for retrieving their license from the servers. Additionally client agents rely on the value of the start_join and retry_join configurations for determining the servers to query for the license. Therefore one must be set to use license auto-retrieval. [GH-10248]
• licensing: (Enterprise Only) Consul Enterprise has removed support for temporary licensing. All server agents must have a valid license at startup and client agents must have a license at startup or be able to retrieve one from the servers. [GH-10248]

FEATURES:

• checks: add H2 ping health checks. [GH-8431]
• cli: Add additional flags to the consul connect redirect-traffic command to allow excluding inbound and outbound ports,
  outbound CIDRs, and additional user IDs from traffic redirection. [GH-10134]
• cli: Add new consul connect redirect-traffic command for applying traffic redirection rules when Transparent Proxy is enabled. [GH-9910]
• cli: Add prefix option to kv import command [GH-9792]
• cli: Automatically exclude ports from envoy_prometheus_bind_addr, envoy_stats_bind_addr, and ListenerPort from Expose config
  from inbound traffic redirection rules if proxy-id flag is provided to the consul connect redirect-traffic command. [GH-10134]
