Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
Expo is at a turning point: the EAS infrastructure layer — build, update, and now observe — is maturing into production-grade tooling, with EAS Observe reaching GA in August and SDK 58 entering beta this week. Simultaneously, Expo shut down its AI Agent experiment after months in closed beta, a signal that building an AI coding assistant directly on the platform didn't reach product-market fit. The MCP server and Claude desktop integration indicate where the AI bet now sits: in connectors, not agents.
Cronicle fixes active-job privilege visibility and chains a run of security dependency patches
Cronicle's recent releases cluster around two themes: access control hardening and dependency security. The v0.9.131 fix applies category and server-group visibility checks to the active job API, login bootstrap, and websocket status payloads — closing a privilege bypass that exposed job activity to users without the right access. Alongside it, a string of vulnerability bumps (nodemailer, nanoid, sanitize-html) and the chained-event bug fix in v0.9.134 round out a security-focused cycle.

Expo is consolidating around EAS as an observable infrastructure layer, not as an AI product builder. The MCP server and third-party integrations (PostHog, Claude) suggest the strategy is to serve as a data and build substrate that AI tools operate on top of. SDK 58 will push new device capabilities through the standard pipeline; EAS Observe data becoming a programmable surface for AI tools is the natural next extension of this approach.
The next move is a stable SDK 58 release and deeper AI-tool integrations via MCP — Expo is betting its AI story on being the substrate that coding assistants operate on, not on shipping its own. Expect more one-command observability integrations to follow PostHog.
Cronicle's recent releases cluster around two themes: access control hardening and dependency security. The v0.9.131 fix applies category and server-group visibility checks to the active job API, login bootstrap, and websocket status payloads — closing a privilege bypass that exposed job activity to users without the right access.

The access control fixes in v0.9.125 and v0.9.131 look like the output of a systematic privilege audit rather than isolated bug reports. Node.js v22 is now officially required, the project is testing against v24, and dependencies are being kept current — all signs of a maintained project, not an abandoned one. No major new features are visible in this window.
A few more targeted privilege-check patches are likely as the access control audit works through the surface. A 1.0 release milestone isn't signaled by anything in the current entries.
