  • v1.10.0-beta3 Changes

    May 27, 2021

    💥 BREAKING CHANGES:

    • 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:

    • 💻 ui: Add Unix Domain Socket support [GH-10287]
    • xds: emit a labeled gauge of connected xDS streams by version [GH-10243]

    • api: The Content-Type header is now always set when a body is present in a request. [GH-10204]
    • areas: (Enterprise only) Use server agent's gossip_wan config when setting memberlist configuration for network areas. Previously they used memberlists WAN defaults.
    • command: Exclude exposed Envoy ports from traffic redirection when providing -proxy-id and Expose.Checks is set. [GH-10173]
    • connect: Avoid adding original_dst listener filter when it won't be used. [GH-10302]
    • connect: Ensures passthrough tproxy cluster is created even when mesh config doesn't exist. [GH-10301]
    • ⚡️ connect: update supported envoy versions to 1.18.3, 1.17.3, 1.16.4, and 1.15.5 [GH-10231]
    • licensing: (Enterprise Only) Consul Enterprise has gained the ability to autoload a license via configuration. This can be specified with the license_path configuration, the CONSUL_LICENSE environment variable or the CONSUL_LICENSE_PATH environment variable [GH-10210]
    • licensing: (Enterprise Only) Consul Enterprise has gained the ability update its license via a configuration reload. The same environment variables and configurations will be used to determine the new license. [GH-10267]
    • 🚚 ui: Add 'optional route segments' and move namespaces to use them [GH-10212]

    • 0️⃣ local: agents will no longer persist the default user token along with a service or check. [GH-10188]
    • namespaces: (Enterprise only) fixes a problem where the logs would contain many warnings about namespaces not being licensed.
