+### Added
+- Partial STAC transaction extension added, disabled by default - set ENABLE_TRANSACTIONS_EXTENSION=true to enable
+
+### Changed
+- Name changed from 'stac-api' to 'stac-server' to avoid confusion with [stac-api-spec](https://github.com/radiantearth/stac-api-spec)
+- Elasticsearch client library updated to @elastic/elasticsearch
+
+### Removed
+- Collection properties no longer merged into Item on ingest (commons extension removed from STAC)

 ## Ingesting Data
 
-STAC Collections and Items are ingested by the `ingest` Lambda function, however this Lambda is not invoked directly by a user, it consumes records from the `stac-api-<stage>-queue` SQS. To add STAC Items or Collections to the queue, publish them to the SNS Topic `stac-api-<stage>-ingest`.
+STAC Collections and Items are ingested by the `ingest` Lambda function, however this Lambda is not invoked directly by a user, it consumes records from the `stac-server-<stage>-queue` SQS. To add STAC Items or Collections to the queue, publish them to the SNS Topic `stac-server-<stage>-ingest`.
 
 STAC Collections should be ingested before Items that belong to that Collection. Items should have the `collection` field populated with the ID of an existing Collection.
 
 ### Subscribing to SNS Topics
 
-Stac-api can also be subscribed to SNS Topics that publish complete STAC Items as their message. This provides a way to keep stac-api up to date with new data. Use the AWS Lambda console for the function `stac-api-<stage>-subscibe-to-sns` to subscribe to an SNS Topic for which you have the full ARN and permission to subscribe to. This could be an SNS Topic you created yourself to publish STAC records to, or a publicly available one, such as for [Sentinel](https://github.com/sat-utils/sat-stac-sentinel).

 ### Ingest Errors
 
-Errors that occur during ingest will end up in the dead letter processing queue, where they are processed by the `stac-api-<stage>-failed-ingest` Lambda function. Currently all the failed-ingest Lambda does is log the error, see the CloudWatch log '/aws/lambda/stac-api-<stage>-failed-ingest' for errors.
