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.

OpenTripPlanner vs Gravity Forms: 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.

G6.3

Gravity Forms ships an MCP server, putting AI assistants on a direct line to WordPress form data.

◆ Current state

Gravity Forms is a stable, mature WordPress form builder in an active maintenance cycle, shipping add-on updates across its ecosystem weekly. Core 3.1.1 brings fixes and additions; SMTP 2.3.3 adds routing controls and security hardening. The product's feature surface is largely set, with incremental polish running in parallel across a wide integration catalog.

◆ Where it's heading

The MCP server launch is the defining move of this period — it connects Gravity Forms directly to AI assistant workflows, a step no other WordPress form builder has taken. A new official Klaviyo Add-On expands first-party marketing automation reach alongside existing Salesforce and HubSpot ties. Gravity Forms is building toward being the data-collection bridge between WordPress sites and modern AI and marketing stacks.

◆ Prediction

Expect AI-assisted form creation and entry analysis features building on the MCP foundation; the protocol provides the surface area that makes AI feature extension tractable.
