Walkthrough

Updates RStudio Workbench minimal images and pipelines from Python 3.11 to 3.12 for both CPU and CUDA variants. Renames components, updates image tags, Dockerfile and build-args paths, pipeline triggers, names, labels, output tags, and service accounts. Version tag advanced in push pipelines (2025a-v1.35 → 2025b-v1.36).

Poem

Thump-thump, I hop to three-one-two,
Fresh carrots, fresher builds anew.
CPU, CUDA, tags aligned,
Docker paths neatly reassigned.
In quay we trust, with ears held high—
Merge me now, and watch me fly! 🥕🚀

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

Please share your feedback with us on this Discord post.
