 # Changelog Chainlink Core
 
+## 2.23.0 - PREVIEW
+
+## added

+- [#16789](https://github.com/smartcontractkit/chainlink/pull/16789) [`4ce1a16`](https://github.com/smartcontractkit/chainlink/commit/4ce1a16b5abe4829e608dc25b112d3006ae9acd4) - Support new report type 'evm_streamlined'. #added
+  This new report type is designed to be as small and optimized as possible to minimize report size and calldata.
+  Reports are encoded as such:
+  (no FeedID specified in opts)
+  ```
+  <32 bits> channel ID
+  <64 bits> unsigned report timestamp nanoseconds
+  <bytes>   report data as packed ABI encoding
+  ```
+  (FeedID specified in opts)
+  ```
+  <256 bits> feed ID
+  <64 bits> unsigned report timestamp nanoseconds
+  <bytes>   report data as packed ABI encoding
+  ```
+  Report contexts are encoded as such:
+  ```
+  // Equivalent to abi.encodePacked(digest, len(report), report, len(sigs), sigs...)
+  // bytes32 config digest
+  // packed uint16 len report
+  // packed bytes report
+  // packed uint8 len sigs
+  // packed bytes sigs
+  ```
+  See report_codec_evm_streamlined_test.go for examples.
+
+- [#16825](https://github.com/smartcontractkit/chainlink/pull/16825) [`390c02c`](https://github.com/smartcontractkit/chainlink/commit/390c02cc3e38fc665829e627e0a49b1aec56b2c2) - Implement support for TimestampedStreamValue data types in LLO (RWAs) #added
+  Support encoding into evm_abi_unpacked or evm_streamlined report formats.
+  ABI must specify how to encode both types, as such:
+  ```json
+  // Encodes the timestamp as uint64 and data payload as int192
+  {
+    "abi": [[{ "type": "uint64" }, { "type": "int192" }]]
+  }
+  ```
+  The first element of the array encodes the timestamp, the second encodes the data payload.
+  Users may suppress one or the other entirely by using the special keyword "bytes0" e.g.
+  ```json
+  // Encodes only the data payload
+  {
+    "abi": [[{ "type": "bytes0" }, { "type": "int192" }]]
+  }
+  ```

 :warning: On **May 31, 2025**, Ubuntu 20.04 will reach end-of-life and will no longer receive security updates. We strongly encourage you to begin upgrading your environments to a stable support Ubuntu versions. **We are bumping the Chainlink image to 24.04 in this release.** We will continue to provide an image that is 20.04 as well to ensure there is ample time to upgrade and remove support as it goes to eol.

 ### Added
 
 - Added support for Keeper registry v1.2 in keeper jobs
-- Added disk rotating logs. Chainlink will now always log to disk at debug level. The default output directory for debug logs is Chainlink's root directory (ROOT_DIR) but can be configured by setting LOG_FILE_DIR. This makes it easier for node operators to report useful debugging information to Chainlink's team, since all the debug logs are conveniently located in one directory. Regular logging to STDOUT still works as before and respects the LOG_LEVEL env var. If you want to log in disk at a particular level, you can pipe STDOUT to disk. This automatic debug-logs-to-disk feature is enabled by default, and will remain enabled as long as the `LOG_FILE_MAX_SIZE` ENV var is set to a value greater than zero. The amount of disk space required for this feature to work can be calculated with the following formula: `LOG_FILE_MAX_SIZE` \* (`LOG_FILE_MAX_BACKUPS` + 1). If your disk doesn't have enough disk space, the logging will pause and the application will log Errors until space is available again. New environment variables related to this feature:

   - `LOG_FILE_MAX_SIZE` (default: 5120mb) - this env var allows you to override the log file's max size (in megabytes) before file rotation.
   - `LOG_FILE_MAX_AGE` (default: 0) - if `LOG_FILE_MAX_SIZE` is set, this env var allows you to override the log file's max age (in days) before file rotation. Keeping this config with the default value means not to remove old log files.
   - `LOG_FILE_MAX_BACKUPS` (default: 1) - if `LOG_FILE_MAX_SIZE` is set, this env var allows you to override the max amount of old log files to retain. Keeping this config with the default value means to retain 1 old log file at most (though `LOG_FILE_MAX_AGE` may still cause them to get deleted). If this is set to 0, the node will retain all old log files instead.
