This message covers changes in this release. The complete change log can be found at [Change Log | Datomic](https://docs.datomic.com/changes/pro.html). To download this release see [Datomic Pro Releases | Datomic](https://docs.datomic.com/releases-pro.html)

## 1.0.7556: 2026/03/13

- Fix: Prevent issue when running both io-stats and query-stats where :ret would nest.
- Performance: Significantly reduce CPU and memory allocation of Datomic’s memory-size routine.
- Dependency upgrade: Datomic now uses AWS Java SDK v2, and has removed dependencies on v1

Peers connecting to DynamoDB storage must depend on `software.amazon.awssdk/dynamodb {:mvn/version "2.31.45"}`

Apps that use AWS SDK v1 classes `com.amazonaws.*` implicitly should make explicit their dependency on v1 libraries or migrate usages to v2.

If your application uses certain logging backends, AWS Java SDK v2 requires these minimum versions

- logback-classic → 1.4.14
- org.slf4j/slf4j-jdk14 → 1.7.36
- org.slf4j/slf4j-log4j12 → 1.7.36

Thanks a lot for the update 🙂 So AWS Java SDK v2 also means backups are finally possible on Google Cloud Storage (with S3-compatiblitly mode)?

@maxweber I haven’t tested that but we will see if that works and circle back.
