Rock 2.3 Released

We are pleased to announce that Rock 2.3 is now available. Rock is OBiBa’s R computation engine.

This Rock release includes:

• GraalVM native binaries (Linux amd64 and arm64) are built on release, as an alternative to running Rock on the JVM.
• Docker images are now based on the Rocker project (rocker/r-ver), with R packages installed as prebuilt binaries from Posit Package Manager. Two variants are published:
  • obiba/rock:2.3.0 (and latest): Rock running on the Eclipse Temurin 25 JRE, the recommended choice for long-running production servers.
  • obiba/rock:2.3.0-native: Rock as a native executable, no Java runtime, with super fast startup and a lower memory footprint (Serial garbage collector only).
• Security fix: Bouncy Castle upgraded to 1.86.
• R repositories configuration clarified: the REST API uses r.repos from application.yml, while the repos option of Rprofile.R only applies to R sessions. The unmaintained cran.obiba.org repository was removed from the defaults.

Additional notes:

• No upgrade action required when Rock is deployed with Docker, just pull the latest image.
• The Rock API has NOT been modified: it will seamlessly integrate with Opal.
