Issue 39 is live. This week we track how agentic workflows are rewriting mobile QA, alongside Expo SDK 58 deep dives, ReactLynx rendering metrics, and an emergency Next.js security patch. Here is what engineering teams need to know. 🧵

AI agents are moving past simple code completion into full execution loops. A new look at agent-device setups shows autonomous workers reproducing crash logs from GitHub issues directly on cloud simulators and opening verified pull requests.

Callstack's new deep dive into Jev explores faster, cheaper AI-driven mobile QA workflows. Paired with video demos, it is clear agentic testing is maturing rapidly for React Native codebases.

Upgrading to Expo SDK 58? Code with Beto breaks down the transition, highlighting new iPhone Duo layout support, native App Intents integration, and faster module initialization.

Cross-platform performance gets a boost from ReactLynx. Their latest architectural teardown explains how bypassing traditional background update pipelines achieves instant first-frame views.

Security alert: maintainers running Next.js must review the recent out-of-band security patch addressing a critical upstream vector immediately.
