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 Zed?

Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.

Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

OpenTripPlanner vs Zed: 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.

5.0

Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.

◆ Current state

Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

◆ Where it's heading

Zed is splitting attention between its agent panel, where ACP agents keep gaining the same session handling as Zed's own, and core editor depth in languages and debugging. Weekly stable releases with community-contributed features and quick model additions remain the pattern.

◆ Prediction

Expect 1.27 next week with more ACP session and model-picker work, plus further debugger and language-server additions.
