Get the unreleased section into the shape RELEASE.md asks for before the release-1.22 cut, so operators reading the notes see the changes that affect them: - Delete the stale duplicate of cortexproject#7375, which already shipped in 1.21.0 as cortexproject#7370. - Re-sort into CHANGE -> FEATURE -> ENHANCEMENT -> BUGFIX. - Correct the gRPC entry: the bump landed at v1.82.1, not v1.79.3. - Fold follow-up PRs into the entry they belong to. - Add three missing user-facing entries: cortexproject#7513, cortexproject#7514 and cortexproject#7559. - Reclassify as CHANGE the entries that break existing configs or log consumers: the sign-key validation (cortexproject#7587), the Alertmanager per-tenant *_file rejections (cortexproject#7767, cortexproject#7768, now one entry) and the time_taken -> time_taken_ms rename (cortexproject#7649). - Note the operator impact of the distroless base image (cortexproject#7637) and of the 500 -> 499 reclassification (cortexproject#7717).

From

#7513— Alertmanager: removal of the legacy state-file migration.#7514—cortex_ingester_head_metric_names.#7559—DoBatchcleanup callback deadlock on panic.Reclassified as CHANGE
These are breaking changes that were filed as
BUGFIX/ENHANCEMENT, so they would nothave appeared in the upgrade notes:
#7587sign-key validation — its own text already says "fail at process startup; audityour configs before upgrading".
#7767+#7768Alertmanager per-tenant*_filerejection — merged into one entry;tenant configs that previously loaded are now rejected.
#7649time_taken→time_taken_ms— renames and re-units a slow-query-log field.Kept in place, with operator impact noted
#7637alpine → distroless. Not config or API, so not aCHANGEby house convention,but the image has no shell — noted that shell-based probes, init scripts and
kubectl execworkflows need adjusting.#7717/#7738500 → 499. A genuine bugfix, but it deflatescortex_request_duration_seconds{status_code="500"}and changes SLO math.Result
7 CHANGE / 14 FEATURE / 37 ENHANCEMENT / 34 BUGFIX = 92 entries (from 91).
Merging this first keeps the other release-prep PRs from all conflicting at the top of the
file.
