What is Expo?
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.
What is runc?
runc now publishes an end-of-life calendar, and three branches shipped the same CVE fix in two days.
1.5.0 in June was the first stable release of the 1.5.z series and the third under runc's formal release and support policy: 1.2.z and earlier are unsupported, 1.3.z receives only high-severity CVE fixes until the end of October 2026, and 1.4.z is limited to security and significant bugfixes. A month later 1.5.1 fixed a real-world regression — the maskPaths optimisation from 1.5.0-rc.3 broke tmpfs mounts with nr_inodes=1 on Ubuntu 20.04 kernels. In mid-June, CVE-2026-41579 was fixed simultaneously across 1.3.6, 1.4.3 and 1.5.0-rc.3 and released with no embargo.

Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
runc
2.5INFRA · APIS
runc now publishes an end-of-life calendar, and three branches shipped the same CVE fix in two days.
◆ Current state
1.5.0 in June was the first stable release of the 1.5.z series and the third under runc's formal release and support policy: 1.2.z and earlier are unsupported, 1.3.z receives only high-severity CVE fixes until the end of October 2026, and 1.4.z is limited to security and significant bugfixes. A month later 1.5.1 fixed a real-world regression — the maskPaths optimisation from 1.5.0-rc.3 broke tmpfs mounts with nr_inodes=1 on Ubuntu 20.04 kernels. In mid-June, CVE-2026-41579 was fixed simultaneously across 1.3.6, 1.4.3 and 1.5.0-rc.3 and released with no embargo.
◆ Where it's heading
The project is behaving like infrastructure with a contract. Publishing dated support windows and shipping a coordinated fix across every live branch on the same day is the operating posture of a component that sits under every container on a host, where operators need to know what they are still entitled to. The CVE itself is instructive: a /dev symlink escape in the same family as three earlier CVEs, found by re-auditing the rootfs preparation code that had been hardened before.
◆ Prediction
1.5.0's notes state that a 1.6.0 is expected in late October 2026, which is also when 1.3.z support ends — so the next milestone is that pairing. Expect 1.5.z patches until then.
