### 3.0 Cleanup

* [CHANGE] **BREAKING CHANGE** Remove ingesters and compactor alerts [#6369](https://github.com/grafana/tempo/pull/6369) (@javiermolinar)
* [CHANGE] **BREAKING CHANGE** Removed `v2` block encoding and compactor component. [#6273](https://github.com/grafana/tempo/pull/6273) (@joe-elliott)
This includes the removal of the following CLI commands which were `v2` specific: `list block`, `list index`, `view index`, `gen index`, `gen bloom`.
* [CHANGE] **BREAKING CHANGE** Sets the `all` target to be 3.0 compatible and removes the `scalable-single-binary` target [#6283](https://github.com/grafana/tempo/pull/6283) (@joe-elliott)

P2 Badge Restore ingester partition coverage in block-builder alert

The updated expression only checks livestore-partitions and drops ingester-partitions. The ingester module still defines and uses the ingester-partitions ring (modules/ingester/ingester.go), so deployments that haven’t migrated off ingesters will no longer get the block‑builder mismatch alert even if partitions are unowned. That’s a regression in monitoring coverage for those clusters: the alert will stay silent while the block‑builder falls behind the ingester partition ring. Consider keeping ingester-partitions in the selector (or gating it by configuration) until ingesters are fully removed.
