Arrow Rust 59.3.1 ships a dozen correctness fixes to the line 60.0.0 replaced.
Apache Arrow Rust's current major, 60.0.0, added PageIndexBuilder and PageIndexProvider APIs for Parquet page indexes and a breaking ownership fix to batches_to_flight_data(). The 59.x line is still maintained: 59.3.1 has gone final with fixes for corrupt arrays from into_builder, a Parquet decoder that could silently read the wrong number of values, oversized Thrift list sizes, and a rustls advisory.
Speakeasy makes AI agents first-class principals: server identity modes, Slack as a work identity, and directory group role mapping
Speakeasy is an enterprise AI agent governance platform shipping at a high cadence — multiple minor versions per week. The current window covers two structural areas: MCP identity management (remote servers now declare User/Agent/No Identity modes, agents own their upstream accounts, wildcard workload admission for agent fleets) and enterprise directory integration (Slack as a work identity, directory group-to-role mapping). The risk policy engine gained scoped targeting for specific MCP servers and tools in the same release window.
Apache Arrow Rust's current major, 60.0.0, added PageIndexBuilder and PageIndexProvider APIs for Parquet page indexes and a breaking ownership fix to batches_to_flight_data(). The 59.x line is still maintained: 59.3.1 has gone final with fixes for corrupt arrays from into_builder, a Parquet decoder that could silently read the wrong number of values, oversized Thrift list sizes, and a rustls advisory.
Parquet is the throughline: each major adds codec support, encodings such as ALP, or page-level infrastructure for predicate pushdown. Alongside the majors, the project keeps the previous line alive with security and correctness backports, so downstream engines can delay a breaking upgrade without going unpatched.
Expect a 60.x point release carrying the same fixes and further work toward the next major on the Parquet page-index and ALP thread. The entries don't show when 59.x maintenance ends.

Speakeasy is building the control plane for enterprise AI agent governance: making agents governable by the same tools that manage human employees — identity, directory sync, role assignment, risk policies, and audit trails. The workload assertion grant (a short-lived MCP session from a platform-issued identity token) is the primitive that makes agent fleets manageable at scale. Each release tightens the coupling between AI agent identity and enterprise identity providers (Slack, OIDC, directory groups).
The next material release will likely extend the Shadow AI scan's person-level visibility into policy actions (block/allow per person per tool), or introduce agent groups as a first-class concept analogous to directory groups — the wildcard workload admission is a precursor to that. Expect tighter Okta Cross App Access integration as that feature exits the readiness/preview stage.
