1.9.0-beta1 (October 12, 2020)

BREAKING CHANGES:

• agent: The enable_central_service_config option now defaults to true. [GH-8746]
• connect: intention destinations can no longer be renamed [GH-8834]
• xds: Drop support for Envoy versions 1.12.0, 1.12.1, 1.12.2, and 1.13.0, due to a lack of support for url_path in RBAC. [GH-8839]

FEATURES:

• agent: Allow client agents to be configured with an advertised reconnect timeout to control how long until the nodes are reaped by others in the cluster. [GH-8781]
• agent: moved ui config options to a new ui_config stanza in agent configuration and added new options to display service metrics in the UI. [GH-8694]
• cli: update snapshot inspect command to provide more detailed snapshot data [GH-8787]
• connect: intentions are now managed as a new config entry kind "service-intentions" [GH-8834]
• connect: support defining intentions using layer 7 criteria [GH-8839]
• server: create new memdb table for storing system metadata [GH-8703]
• telemetry: track node and service counts and emit them as metrics [GH-8603]
• ui: If Prometheus is being used for monitoring the sidecars, the topology view can be configured to display overview metrics for the services. [GH-8858]
• ui: Services using Connect with Envoy sidecars have a topology tab in the UI showing their upstream and downstream services. [GH-8788]
• xds: use envoy's rbac filter to handle intentions entirely within envoy [GH-8569]

IMPROVEMENTS:

• agent: Return HTTP 429 when connections per clients limit (limits.http_max_conns_per_client) has been reached GH-7527. [GH-8221]
• agent: add config flag telemetry { disable_compat_1.9 = (true|false) } to disable deprecated metrics in 1.9 [GH-8877]
• agent: add counter consul.api.http with labels for each HTTP path and method. This is intended to replace consul.http... [GH-8877]
• agent: allow the /v1/connect/intentions/match endpoint to use the agent cache [GH-8875]
• api: The v1/connect/ca/roots endpoint now accepts a pem=true query parameter and will return a PEM encoded certificate chain of
  all the certificates that would normally be in the JSON version of the response. [GH-8774]
• api: support GetMeta() and GetNamespace() on all config entry kinds [GH-8764]
• checks: add health status to the failure message when gRPC healthchecks fail. [GH-8726]
• command: remove conditional envoy bootstrap generation for versions <=1.10.0 since those are not supported [GH-8855]
• connect: The Vault provider will now automatically renew the lease of the token used, if supported. [GH-8560]
• connect: add support for specifying load balancing policy in service-resolver [GH-8585]
• deps: Update raft to v1.2.0 to prevent non-voters from becoming eligible for leader elections and adding peer id as metric label to reduce cardinality in metric names [GH-8822]
• server: (Consul Enterprise only) ensure that we also shutdown network segment serf instances on server shutdown [GH-8786]
• server: make sure that the various replication loggers use consistent logging [GH-8745]
• snapshot agent: Deregister critical snapshotting TTL check if leadership is transferred.
• ui: Upstream and downstream services in the topology tab will show a visual indication if a deny intention or intention with L7 policies is configured. [GH-8846]

DEPRECATIONS:

• agent: The measurements in all of the consul.http... prefixed metrics have been migrated to consul.api.http. consul.http... prefixed metrics will be removed in a future version of Consul. [GH-8877]
• agent: ui, ui_dir and ui_content_path are now deprecated for use in agent configuration files. Use ui_config.{enable, dir, content_path} instead. The command arguments -ui, -ui-dir, and -ui-content-path remain supported. [GH-8694]

BUG FIXES:

• agent: make the json/hcl decoding of ConnectProxyConfig fully work with CamelCase and snake_case [GH-8741]
• agent: when enable_central_service_config is enabled ensure agent reload doesn't revert check state to critical [GH-8747]
• connect: Fixed an issue where the Vault intermediate was not renewed in the primary datacenter. [GH-8784]
• connect: fix Vault provider not respecting IntermediateCertTTL [GH-8646]
• connect: use stronger validation that ingress gateways have compatible protocols defined for their upstreams [GH-8470]
• fixed a bug that caused logs to be flooded with [WARN] agent.router: Non-server in server-only area [GH-8685]
• license: (Enterprise only) Fixed an issue where the UI would see Namespaces and SSO as licensed when they were not.
• raft: (Enterprise only) properly update consul server meta non_voter for non-voting Enterprise Consul servers [GH-8731]
• ui: show correct datacenter for gateways [GH-8704]
