* [CHANGE] `go get github.com/prometheus/alertmanager/ui` will now fail as compiled UI assets are no longer checked into the repository. Downstream builds that rely on these assets being present in the source tree must now build the UI from source. prometheus#5113 * [CHANGE] The '--enable-feature=auto-gomaxprocs' option is deprecated and will be removed in v0.33. This flag currently has no effect and can be safely removed from any startup scripts. prometheus#5090 * [CHANGE] Update internal function signatures across multiple packages. This affects any project that integrates `Alertmanager` code. * [ENHANCEMENT] Add static asset caching. prometheus#5113 * [ENHANCEMENT] Reduce memory allocations through pre-sizing collections and batch allocation. prometheus#5020 * [ENHANCEMENT] Replace help with documentation in navigation bar. prometheus#4943 * [ENHANCEMENT] docs(ha): Update high availability documentation. prometheus#5136 * [ENHANCEMENT] docs: Add `auth_secret_file` for smtp in document. prometheus#5036 * [ENHANCEMENT] docs: Add description for global `telegram_bot_token`. prometheus#5114 * [ENHANCEMENT] docs: Add note about notifier timeouts. prometheus#5077 * [ENHANCEMENT] docs: Fix `force_implicit_tls` config field name. prometheus#5030 * [ENHANCEMENT] docs: Link community supported integrations. prometheus#4978 * [ENHANCEMENT] docs: Remove duplicate header. prometheus#5034 * [ENHANCEMENT] docs: Update mutual tls reference in high availability documentation. prometheus#5120 * [ENHANCEMENT] tracing: Use noop spans when tracing disabled. prometheus#5118 * [FEATURE] Add silence annotations. prometheus#4965 * [FEATURE] Add silence logging option. prometheus#4163 * [FEATURE] Add support for multiple matcher set silences. prometheus#4957 * [FEATURE] Add the reason for notifying in dedup stage. prometheus#4971 * [FEATURE] mattermost: Flatten attachments into top-level config. prometheus#5009 * [FEATURE] mattermost: Support global webhook url. prometheus#4998 * [FEATURE] slack: Add default color from template. prometheus#5014 * [FEATURE] slack: Allow receiver to edit existing messages. prometheus#5007 * [FEATURE] template: Add dict, map and append functions. prometheus#5093 * [FEATURE] webhook: Add full payload templating support for notifier. prometheus#5011 * [BUGFIX] config: Check for empty cluster tls client config. prometheus#5126 * [BUGFIX] config: Don't crash upon reading empty config for notifier. prometheus#4979 * [BUGFIX] config: Fix ipv6 address handling in hostport.string(). prometheus#5040 * [BUGFIX] mattermost: Omit empty text field in notifications. prometheus#4985 * [BUGFIX] telegram: Send fallback message when notification exceeds character limit. prometheus#5074 * [BUGFIX] ui: Fix escaping for matcher values with quotes. prometheus#4862 * [BUGFIX] ui: Handle special chars in silence regex-matchers. prometheus#4942 * [BUGFIX] ui: Support utf-8 label names in matchers. prometheus#5089 Signed-off-by: Solomon Jacobs <solomonjacobs@protonmail.com>
