[CHANGE] Distributor: Drop experimental -distributor.direct-otlp-translation-enabled flag, since direct OTLP translation is well tested at this point. #9647
[CHANGE] Ingester: Change -initial-delay for circuit breakers to begin when the first request is received, rather than at breaker activation. #9842
[CHANGE] Query-frontend: apply query pruning before query sharding instead of after. #9913
[CHANGE] Ingester: remove experimental flags -ingest-storage.kafka.ongoing-records-per-fetch and -ingest-storage.kafka.startup-records-per-fetch. They are removed in favour of -ingest-storage.kafka.max-buffered-bytes. #9906
[CHANGE] Ingester: Replace cortex_discarded_samples_total label from sample-out-of-bounds to sample-timestamp-too-old. #9885
[CHANGE] Ruler: the /prometheus/config/v1/rules does not return an error anymore if a rule group is missing in the object storage after been successfully returned by listing the storage, because it could have been deleted in the meanwhile. #9936
[CHANGE] Querier: The . pattern in regular expressions in PromQL matches newline characters. With this change regular expressions like .* match strings that include \n. To maintain the old behaviour, you will have to change regular expressions by replacing all . patterns with [^\n], e.g. foo[^\n]*. This upgrades PromQL compatibility from Prometheus 2.0 to 3.0. #9844
[CHANGE] Querier: Lookback and range selectors are left open and right closed (previously left closed and right closed). This change affects queries and subqueries when the evaluation time perfectly aligns with the sample timestamps. For example assume querying a timeseries with evenly spaced samples exactly 1 minute apart. Previously, a range query with 5m would usually return 5 samples, or 6 samples if the query evaluation aligns perfectly with a scrape. Now, queries like this will always return 5 samples. This upgrades PromQL compatibility from Prometheus 2.0 to 3.0. #9844#10188
[FEATURE] Distributor: Add support for lz4 OTLP compression. #9763
[FEATURE] Query-frontend: added experimental configuration options query-frontend.cache-errors and query-frontend.results-cache-ttl-for-errors to allow non-transient responses to be cached. When set to true error responses from hitting limits or bad data are cached for a short TTL. #9028
[FEATURE] Query-frontend: add middleware to control access to specific PromQL experimental functions on a per-tenant basis. #9798
[FEATURE] Alertmanager: limit added for maximum size of the Grafana state (-alertmanager.max-grafana-state-size-bytes). #9475

[FEATURE] Distributor: Added -api.skip-label-count-validation-header-enabled option to allow skipping label count validation on the HTTP write path based on X-Mimir-SkipLabelCountValidation header being true or not. #9576
[FEATURE] Ruler: Add experimental support for caching the contents of rule groups. This is disabled by default and can be enabled by setting -ruler-storage.cache.rule-group-enabled. #9595#10024

[FEATURE] Distributor: Support promotion of OTel resource attributes to labels. #8271
[FEATURE] Querier: Add experimental double_exponential_smoothing PromQL function. Experimental functions are disabled by default, but can be enabled by setting -querier.promql-experimental-functions-enabled=true in the query-frontend and querier. #9844
[FEATURE] Distributor: Add experimental memberlist KV store for ha_tracker. You can enable it using the -distributor.ha-tracker.kvstore.store flag. You can configure Memberlist parameters via the -memberlist-* flags. #10054
[FEATURE] Distributor: Add experimental -distributor.otel-keep-identifying-resource-attributes option to allow keeping service.instance.id, service.name and service.namespace in target_info on top of converting them to the instance and job labels. #10216
[ENHANCEMENT] mimirtool: Adds bearer token support for mimirtool's analyze ruler/prometheus commands. #9587
[ENHANCEMENT] Ruler: Support exclude_alerts parameter in <prometheus-http-prefix>/api/v1/rules endpoint. #9300
[ENHANCEMENT] Distributor: add a metric to track tenants who are sending newlines in their label values called cortex_distributor_label_values_with_newlines_total. #9400
[ENHANCEMENT] Ingester: improve performance of reading the WAL. #9508
[ENHANCEMENT] Query-scheduler: improve the errors and traces emitted by query-schedulers when communicating with queriers. #9519
[ENHANCEMENT] Compactor: uploaded blocks cannot be bigger than max configured compactor time range, and cannot cross the boundary for given time range. #9524
[ENHANCEMENT] The distributor now validates that received label values only contain allowed characters. #9185
[ENHANCEMENT] Add SASL plain authentication support to Kafka client used by the experimental ingest storage. Configure SASL credentials via the following settings: #9584
-ingest-storage.kafka.sasl-password
-ingest-storage.kafka.sasl-username
[ENHANCEMENT] memberlist: TCP transport write path is now non-blocking, and is configurable by new flags: #9594
-memberlist.max-concurrent-writes
-memberlist.acquire-writer-timeout
[ENHANCEMENT] memberlist: Notifications can now be processed once per interval specified by -memberlist.notify-interval to reduce notify storm CPU activity in large clusters. #9594

[ENHANCEMENT] Querier: Enable the optional querying of additional storage queryables. #9712
[ENHANCEMENT] Ingester: Disable the push circuit breaker when ingester is in read-only mode. #9760
[ENHANCEMENT] Ingester: Reduced lock contention in the PostingsForMatchers cache. #9773
[ENHANCEMENT] Storage: Allow HTTP client settings to be tuned for GCS and Azure backends via an http block or corresponding CLI flags. This was already supported by the S3 backend. #9778
[ENHANCEMENT] Ruler: Support group_limit and group_next_token parameters in the <prometheus-http-prefix>/api/v1/rules endpoint. #9563
[ENHANCEMENT] Ingester: improved lock contention affecting read and write latencies during TSDB head compaction. #9822
[ENHANCEMENT] Distributor: when a label value fails validation due to invalid UTF-8 characters, don't include the invalid characters in the returned error. #9828
[ENHANCEMENT] Ingester: when experimental ingest storage is enabled, do not buffer records in the Kafka client when fetch concurrency is in use. #9838#9850
[ENHANCEMENT] Compactor: refresh deletion marks when updating the bucket index concurrently. This speeds up updating the bucket index by up to 16 times when there is a lot of blocks churn (thousands of blocks churning every cleanup cycle). #9881
[ENHANCEMENT] PromQL: make sort_by_label stable. #9879
[ENHANCEMENT] Distributor: Initialize ha_tracker cache before ha_tracker and distributor reach running state and begin serving writes. #9826#9976

[ENHANCEMENT] Ingester: Add -blocks-storage.tsdb.bigger-out-of-order-blocks-for-old-samples to build 24h blocks for out-of-order data belonging to the previous days instead of building smaller 2h blocks. This reduces pressure on compactors and ingesters when the out-of-order samples span multiple days in the past. #9844#10033#10035
[ENHANCEMENT] Distributor: allow a different limit for info series (series ending in _info) label count, via -validation.max-label-names-per-info-series. #10028
[ENHANCEMENT] Ingester: do not reuse labels, samples and histograms slices in the write request if there are more entries than 10x the pre-allocated size. This should help to reduce the in-use memory in case of few requests with a very large number of labels, samples or histograms. #10040

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code (MAC), which then allows an attacker who has write access to the target's S3 bucket and can observe whether or not an endpoint with access to the key can decrypt a file, they can reconstruct the plaintext with (on average) 128*length (plaintext) queries to the endpoint, by exploiting CBC's ability to manipulate the bytes of the next block and PKCS5 padding errors. It is recommended to update your SDK to V2 or later, and re-encrypt your files.

Description
A vulnerability in the in-band key negotiation exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. An attacker with write access to the targeted bucket can change the encryption algorithm of an object in the bucket, which can then allow them to change AES-GCM to AES-CTR. Using this in combination with a decryption oracle can reveal the authentication key used by AES-GCM as decrypting the GMAC tag leaves the authentication key recoverable as an algebraic equation. It is recommended to update your SDK to V2 or later, and re-encrypt your files.
