v0.40.0 - 2025 10 27
Fixed
- #8334 Query: wait for initial endpoint discovery before becoming ready
- #8486 Receive: fix exemplar label corruption from Cap'n Proto memory references
- #8499 Query: support UTF-8 label names for the
/api/v1/label/:name/valuesAPI. - #8336 store: fix race between lazy index header creation
Added
- #8366 Store: optionally ignore Parquet migrated blocks
- #8359 Tools: add
--shipper.upload-compactedflag for uploading compacted blocks to bucket upload-blocks - #8484 Query: add
/api/v1/status/tsdbAPI endpoint. - #8454 Compact: ensure we don't mark blocks for deletion again after just deleting them
- #8410 Compact: ignore blocks with deletion mark in partial deletes
Changed
- #8370 Query: announced labelset now reflects relabel-config
- #8464 Query: assume that we do not unmark a block for deletion. This solves a race between Thanos Store and Compactor.
- #8402 Query/Receive: trim labelsets in String()
- #8334 Query: wait for initial endpoint discovery before becoming ready
- #8401 block/compact: rework consistency check, make writers only write
- #8389 block: bust cache if modified timestamp differs

In short: there are a bunch of fixes and small improvements. The shining items in this release are memory usage improvements in Thanos Query and shuffle sharding support in Thanos Receiver. Information about shuffle sharding support is available in the documentation. Thank you to all contributors!

- #8308 Receive: Prometheus counters for pending write requests and series requests
- #8225 tools: Extend bucket ls options.
- #8238 Receive: add shuffle sharding support
- #8284 Store: Add
--disable-admin-operationsFlag to Store Gateway - #8245 Querier/Query-Frontend/Ruler: Add
--enable-feature=promql-experimental-functionsflag option to enable using promQL experimental functions in respective Thanos components - #8259 Shipper: Add
--shipper.skip-corrupted-blocksflag to allowSync()to continue upload when finding a corrupted block
Changed
- #8282 Force sync writes to meta.json in case of host crash
- #8192 Sidecar: fix default get config timeout
- #8202 Receive: Unhide
--tsdb.enable-native-histogramsflag - #8315 Query-Frontend: only ready if downstream is ready
Removed
- #8289 Receive: breaking
⚠️ Removed migration of legacy-TSDB to multi-TSDB. Ensure you are running version >0.13
