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
