   ([#23229](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/23229))
+- (Contrib) `attributesprocessor`: Enable SHA-256 as hashing algorithm by default for attributesprocessor hashing action ([#4759](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/4759))
+- (Contrib) `windowseventlogreceiver`: Emit raw Windows events as strings instead of byte arrays ([#22704](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22704))
+- (Contrib) `pkg/ottl`: Removes `StandardTypeGetter` in favor of `StandardStringGetter`, `StandardIntGetter`, `StandardFloatGetter`, and `StandardPMapGetter`, which handle converting pcommon.Values of the proper type. ([#22763](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22763))
+  This is only a breaking change for users using OTTL in custom components. For all Contrib components this is an enhancement.
+- (Contrib) `postgresqlreceiver`: Remove resource attribute feature gates ([#22479](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22479))
+
+### 💡 Enhancements 💡
+
+- (Splunk) `smartagentreceiver`: Add `kubernetes-cluster` config option to sync node labels as properties on the `kubernetes_node` dimension ([#3267](https://github.com/signalfx/splunk-otel-collector/pull/3267))
+- (Splunk) Discovery mode: Support `splunk.discovery` mapping in properties.discovery.yaml ([#3238](https://github.com/signalfx/splunk-otel-collector/pull/3238))
+- (Splunk) Upgrade to the latest Java agent version [v1.25.0](https://github.com/signalfx/splunk-otel-java/releases/tag/v1.25.0) ([#3272](https://github.com/signalfx/splunk-otel-collector/pull/3272))
+- (Contrib) `jmxreceiver`: Add the JMX metrics gatherer version 1.26.0-alpha to the supported jars hash list ([#22042](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22042))
+- (Contrib) `receivers`: Adding `initial_delay` to receivers to control when scraping interval starts ([#23030](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/23030))
+  The updated receivers are:
+  - `oracledb`
+  - `postgresql`
+  - `sqlquery`
+  - `windowsperfcounters`
+- (Contrib) `oracledbreceiver`: Add a simpler alternative configuration option ([#22087](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22087))
+- (Contrib) `pkg/ottl`: Add `body.string` accessor to ottllog ([#22786](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22786))
+- (Contrib) `pkg/ottl`: Allow indexing map and slice log bodies ([#17396](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/17396), [#22068](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22068))
+- (Contrib) `pkg/ottl`: Add hash converters/functions for OTTL ([#22725](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22725))
+- (Contrib) `splunkhecreceiver`: Support different strategies for splitting payloads when receiving a request with the Splunk HEC receiver ([#22788](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22788))
+- (Contrib) `exporter/splunk_hec`: Apply compression to Splunk HEC payload unconditionally if it's enabled in the config ([#22969](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22969), [#22018](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22018))
+  The compression used to be enabled only if the payload size was greater than 1.5KB which significantly
+  complicated the logic and made it hard to test. This change makes the compression unconditionally applied to
+  the payload if it's enabled in the config. The benchmarking shows improvements in the throughput and CPU usage for
+  large payloads and expected degradation for small payloads which is acceptable given that it's not a common case.
+- (Core) `otelcol`: Add connectors to output of the `components` command ([#7809](https://github.com/open-telemetry/opentelemetry-collector/pull/7809))
+- (Core) `scraperhelper`: Will start calling scrapers on component start. ([#7635](https://github.com/open-telemetry/opentelemetry-collector/pull/7635))
+  The change allows scrapes to perform their initial scrape on component start
+  and provide an initial delay. This means that scrapes will be delayed by `initial_delay`
+  before first scrape and then run on `collection_interval` for each consecutive interval.
+- (Core) `batchprocessor`: Change multiBatcher to use sync.Map, avoid global lock on fast path ([#7714](https://github.com/open-telemetry/opentelemetry-collector/pull/7714))
+- (Core, Contrib, Splunk) Third-party dependency updates.
+
+### 🧰 Bug fixes 🧰
+
+- (Splunk) `smartagentreceiver` add missing `monitorID` logger field to `http` monitor ([#3261](https://github.com/signalfx/splunk-otel-collector/pull/3261))
+- (Contrib) `jmxreceiver`: Fixed the issue where the JMX receiver's subprocess wasn't canceled upon shutdown, resulting in a rogue java process. ([#23051](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/23051))
+- (Contrib) `internal/filter/filterlog`: fix filtering non-string body by bodies property ([#22736](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22736))
+  Affects `filterprocessor` and `attributesprocessor`.
+- (Contrib) `prometheusreceiver`: Remove sd_file validations from config.go in Prometheus Receiver to avoid failing Collector with error as this behaviour is incompatible with the Prometheus. ([#21509](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/21509))
+- (Contrib) `fileexporter`: Fixes broken lines when rotation is set. ([#22747](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/22747))
+- (Contrib) `exporter/splunk_hec`: Make sure the `max_event_size` option is used to drop events larger than `max_event_size` instead of using it for batch size. ([#18066](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/18066))
+- (Contrib) `postgresqlreceiver`: Fix race condition when capturing errors from multiple requests simultaneously ([#23026](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/23026))
+- (Contrib) `prometheusreceiver`: The prometheus receiver now sets a full, versioned user agent. ([#21910](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/21910))
+- (Contrib) `splunkhecreceiver`: Fix reusing the same splunkhecreiver between logs and metrics ([#22848](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/22848))
+- (Core) `connectors`: When replicating data to connectors, consider whether the next pipeline will mutate data ([#7776](https://github.com/open-telemetry/opentelemetry-collector/issues/7776))
