-* [CHANGE] Fix for CVE-2021-31232: Local file disclosure vulnerability when `-experimental.alertmanager.enable-api` is used. The HTTP basic auth `password_file` can be used as an attack vector to send any file content via a webhook. The alertmanager templates can be used as an attack vector to send any file content because the alertmanager can load any text file specified in the templates list. #4129
 * [CHANGE] Alertmanager now removes local files after Alertmanager is no longer running for removed or resharded user. #3910
 * [CHANGE] Alertmanager now stores local files in per-tenant folders. Files stored by Alertmanager previously are migrated to new hierarchy. Support for this migration will be removed in Cortex 1.11. #3910
 * [CHANGE] Ruler: deprecated `-ruler.storage.*` CLI flags (and their respective YAML config options) in favour of `-ruler-storage.*`. The deprecated config will be removed in Cortex 1.11. #3945

 * [CHANGE] Querier: removed the config option `-store.max-look-back-period`, which was deprecated in Cortex 1.6 and was used only by the chunks storage. You should use `-querier.max-query-lookback` instead. #4101
 * [CHANGE] Query Frontend: removed the config option `-querier.compress-http-responses`, which was deprecated in Cortex 1.6. You should use`-api.response-compression-enabled` instead. #4101
 * [CHANGE] Runtime-config / overrides: removed the config options `-limits.per-user-override-config` (use `-runtime-config.file`) and `-limits.per-user-override-period` (use `-runtime-config.reload-period`), both deprecated since Cortex 0.6.0. #4112
+* [CHANGE] Cortex now fails fast on startup if unable to connect to the ring backend. #4068
 * [FEATURE] The following features have been marked as stable: #4101
   - Shuffle-sharding
   - Querier support for querying chunks and blocks store at the same time

 * [BUGFIX] Compactor: Increment `cortex_compactor_runs_failed_total` if compactor failed compact a single tenant. #4094
 * [BUGFIX] Tracing: hot fix to avoid the Jaeger tracing client to indefinitely block the Cortex process shutdown in case the HTTP connection to the tracing backend is blocked. #4134
