Some of the highlights include OpenTelemetry support, Azure support has been improved with a new SDK, increased query speed, receive has new features to limit series per tenant.
First, let's celebrate new contributors, and then you can find the changelog where you can find all of the details. Please try it out and let us know if you spot any problems!

Fixed
- #5642 Receive: Log labels correctly in writer debug messages.
- #5655 Receive: Fix recreating already pruned tenants.
- #5702 Store: Upgrade minio-go/v7 to fix panic caused by leaked goroutines.
- #5736 Compact: Fix crash in GatherNoCompactionMarkFilter.NoCompactMarkedBlocks.
- #5763 Compact: Enable metadata cache.
- #5759 Compact: Fix missing duration log key.
- #5799 Query Frontend: Fixed sharding behaviour for vector matches. Now queries with sharding should work properly where the query looks like:
foo and without (lbl) bar.
Added
- #5565 Receive: Allow remote write request limits to be defined per file and tenant (experimental).
- #5654 Query: add
--grpc-compressionflag that controls the compression used in gRPC client. With the flag it is now possible to compress the traffic between Query and StoreAPI nodes - you get lower network usage in exchange for a bit higher CPU/RAM usage.
- #5650 Query Frontend: Add sharded queries metrics.
thanos_frontend_sharding_middleware_queries_totalshows how many queries were sharded or not sharded. - #5658 Query Frontend: Introduce new optional parameters (
query-range.min-split-interval,query-range.max-split-interval,query-range.horizontal-shards) to implement more dynamic horizontal query splitting. - #5721 Store: Add metric
thanos_bucket_store_empty_postings_totalfor number of empty postings when fetching series. - #5723 Compactor: Support disable block viewer UI.
- #5674 Query Frontend/Store: Add support connecting to redis using TLS.
- #5734 Store: Support disable block viewer UI.
- #5411 Tracing: Add OpenTelemetry Protocol exporter.
- #5779 Objstore: Support specifying S3 storage class.
- #5741 Query: add metrics on how much data is being selected by downstream Store APIs.
- #5673 Receive: Reload tenant limit configuration on file change.
- #5749 Query Frontend: Added small LRU cache to cache query analysis results.
Changed
- #5738 Global: replace
crypto/sha256withminio/sha256-simdto make hash calculation faster in metadata and reloader packages. - #5648 Query Frontend: cache vertical shards in query-frontend.
- #5753 Build with Go 1.19.
- #5255 Query: Use k-way merging for the proxying logic. The proxying sub-system now uses much less resources (~25-80% less CPU usage, ~30-50% less RAM usage according to our benchmarks). Reduces query duration by a few percent on queries with lots of series.
- #5690 Compact: update
--debug.accept-malformed-indexflag to apply to downsampling. Previously the flag only applied to compaction, and fatal errors would still occur when downsampling was attempted. - #5707 Objstore: Update objstore to latest version which includes a refactored Azure Storage Account implementation with a new SDK.
- #5641 Store: Remove hardcoded labels in shard matcher.
- #5641 Query: Inject unshardable le label in query analyzer.
- #5685 Receive: Make active/head series limiting configuration per tenant by adding it to new limiting config.
- #5411 Tracing: Change Jaeger exporter from OpenTracing to OpenTelemetry. Options
RPC Metrics,Gen128BitandDisabledare now deprecated and won't have any effect when set ⚠️. - #5767 *: Upgrade Prometheus to v2.39.0.
- #5771 *: Upgrade Prometheus to v2.39.1.
