What is OpenTripPlanner?

OpenTripPlanner v2.10 delivers routing performance improvements after v2.8's REST API removal

OpenTripPlanner completed its REST API removal in v2.8.0 (September 2025) and has since consolidated around GTFS GraphQL and Transmodel GraphQL as its two canonical API surfaces. v2.10.0 (September 2026) continues this with broad routing and graph build performance improvements across more than 14 pull requests, plus TransitGroupPriority graduating from experimental to official status. The product releases approximately twice yearly with a predictable cadence.

What is CodeRabbit?

CodeRabbit moves review rules into a .coderabbit/ folder that sits next to the code.

CodeRabbit is moving from commenting on pull requests to deciding on them. Risk instructions let a team say what is routine and what is risky, so CodeRabbit approves the routine ones and a Triage rule can merge them on GitHub Team plans. This week it locked configuration to a protected branch, added a .coderabbit/ directory where review instructions and pre-merge checks live as Markdown per package, and retired Generate docstrings and the Docstring Coverage check.

OpenTripPlanner vs CodeRabbit: editorial side-by-side

O2.5

OpenTripPlanner v2.10 delivers routing performance improvements after v2.8's REST API removal

◆ Current state

OpenTripPlanner completed its REST API removal in v2.8.0 (September 2025) and has since consolidated around GTFS GraphQL and Transmodel GraphQL as its two canonical API surfaces. v2.10.0 (September 2026) continues this with broad routing and graph build performance improvements across more than 14 pull requests, plus TransitGroupPriority graduating from experimental to official status. The product releases approximately twice yearly with a predictable cadence.

◆ Where it's heading

OTP has executed a multi-version API transition: REST deprecated in 2.5, disabled by default in 2.6, fully removed in 2.8 — now complete. The current focus is routing performance and API stability within the GraphQL-based surface. Java runtime upgrades (Java 21 in 2.5, Java 25 in 2.9) signal ongoing investment in keeping the server runtime current with LTS releases. No pivot is visible; this is execution on an established roadmap.

◆ Prediction

Expect v2.11 around March 2027, continuing the semi-annual cadence. Further Transmodel API enhancements and GTFS-RT or SIRI integration work are the most likely additions based on the recent trajectory.

C6.3

CodeRabbit moves review rules into a .coderabbit/ folder that sits next to the code.

◆ Current state

CodeRabbit is moving from commenting on pull requests to deciding on them. Risk instructions let a team say what is routine and what is risky, so CodeRabbit approves the routine ones and a Triage rule can merge them on GitHub Team plans. This week it locked configuration to a protected branch, added a .coderabbit/ directory where review instructions and pre-merge checks live as Markdown per package, and retired Generate docstrings and the Docstring Coverage check.

◆ Where it's heading

With approval authority comes tighter control over who writes the rules: protected config branches, then rules stored per package so each service owns its own definition of risky. The product is also trimming side features such as docstring generation to concentrate on review and merge decisions.

◆ Prediction

Expect risk instructions and Automatic Approvals to read from the .coderabbit/ directory per package, and more platforms beyond GitHub Cloud getting the directory and config-source controls.
