*: cut 0.29.0-rc.0 (#5806)

* *: cut 0.29.0-rc.0

This looks like one of the bigger releases. I suggest releasing this now
to make it smaller even though we have some exciting things in the
pipeline.

 ### Fixed
 - [#5642](https://github.com/thanos-io/thanos/pull/5642) Receive: Log labels correctly in writer debug messages.
 - [#5655](https://github.com/thanos-io/thanos/pull/5655) Receive: Fix recreating already pruned tenants.
 - [#5702](https://github.com/thanos-io/thanos/pull/5702) Store: Upgrade minio-go/v7 to fix panic caused by leaked goroutines.
 - [#5736](https://github.com/thanos-io/thanos/pull/5736) Compact: Fix crash in GatherNoCompactionMarkFilter.NoCompactMarkedBlocks.
 - [#5763](https://github.com/thanos-io/thanos/pull/5763) Compact: Enable metadata cache.
+- [#5759](https://github.com/thanos-io/thanos/pull/5759) Compact: Fix missing duration log key.
+- [#5799](https://github.com/thanos-io/thanos/pull/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](https://github.com/thanos-io/thanos/pull/5565) Receive: Allow remote write request limits to be defined per file and tenant (experimental).
 * [#5654](https://github.com/thanos-io/thanos/pull/5654) Query: add `--grpc-compression` flag 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](https://github.com/thanos-io/thanos/pull/5650) Query Frontend: Add sharded queries metrics.
+- [#5650](https://github.com/thanos-io/thanos/pull/5650) Query Frontend: Add sharded queries metrics. `thanos_frontend_sharding_middleware_queries_total` shows how many queries were sharded or not sharded.
 - [#5658](https://github.com/thanos-io/thanos/pull/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](https://github.com/thanos-io/thanos/pull/5721) Store: Add metric `thanos_bucket_store_empty_postings_total` for number of empty postings when fetching series.
 - [#5723](https://github.com/thanos-io/thanos/pull/5723) Compactor: Support disable block viewer UI.

+- [#5749](https://github.com/thanos-io/thanos/pull/5749) Query Frontend: Added small LRU cache to cache query analysis results.
 
 ### Changed
 
+- [#5738](https://github.com/thanos-io/thanos/pull/5738) Global: replace `crypto/sha256` with `minio/sha256-simd` to make hash calculation faster in metadata and reloader packages.
+- [#5648](https://github.com/thanos-io/thanos/pull/5648) Query Frontend: cache vertical shards in query-frontend.
+- [#5753](https://github.com/thanos-io/thanos/pull/5753) Build with Go 1.19.
 - [#5255](https://github.com/thanos-io/thanos/pull/5296) 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](https://github.com/thanos-io/thanos/pull/5690) Compact: update `--debug.accept-malformed-index` flag to apply to downsampling. Previously the flag only applied to compaction, and fatal errors would still occur when downsampling was attempted.
 - [#5707](https://github.com/thanos-io/thanos/pull/5707) Objstore: Update objstore to latest version which includes a refactored Azure Storage Account implementation with a new SDK.
