What is Apache Arrow Rust?

Arrow Rust 60.1.0 ships, redacting Parquet encryption keys and adding read-ahead planning.

Arrow Rust published 60.1.0 on Oct 28, the first minor on the 60 line. It redacts Parquet encryption keys from Debug output and adds a scan_plan for read-ahead in the Parquet push decoder, a separate page-index decoder, per-column page row limits, interleaved batch coalescing and new ArrayReader/ArrayIterator concepts. Two days earlier 59.3.2 and 58.4.1 shipped with a use-after-free fix in Buffer::shrink_to_fit and other correctness backports, and 57.3.2 is also out.

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.

Apache Arrow Rust vs OpenTripPlanner: editorial side-by-side

A5.0

Arrow Rust 60.1.0 ships, redacting Parquet encryption keys and adding read-ahead planning.

◆ Current state

Arrow Rust published 60.1.0 on Oct 28, the first minor on the 60 line. It redacts Parquet encryption keys from Debug output and adds a scan_plan for read-ahead in the Parquet push decoder, a separate page-index decoder, per-column page row limits, interleaved batch coalescing and new ArrayReader/ArrayIterator concepts. Two days earlier 59.3.2 and 58.4.1 shipped with a use-after-free fix in Buffer::shrink_to_fit and other correctness backports, and 57.3.2 is also out.

◆ Where it's heading

The project ships new Parquet decoding APIs on the current major while pushing memory-safety and data-correctness fixes to three older lines, which suggests downstream engines pin old majors for long periods. The Parquet work keeps aiming at async, push-based reading with finer control over I/O.

◆ Prediction

Expect 61.0.0 on the usual major cadence, with more push-decoder and page-index APIs, while 59.x and 58.x get further backports.

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.
