Summary
ArcadeDB version 25.4.1 introduces significant modernizations, most notably migrating the core dependency from Java 17 to Java 21 and enabling HTTP/2 support. Key new features include an improved connection strategy for High Availability setups, the ability to define unidirectional edges in the schema, an improved space reclaim, and the adoption of Java's modern HttpClient for remote operations.
This release also addresses numerous bugs, enhancing stability and performance. Critical fixes were applied to resolve issues with the HTTP serializer, asynchronous index rebuilding, SQL behavior (including default values and INSERT/UPDATE logic), edge deletion, GraphQL documents, Studio login, HTTPS connections, and several problems within the Postgres driver concerning null values and query results. Additionally, the release incorporates various miscellaneous improvements to builds, documentation, testing, and updates numerous dependencies.
