Meta
Jest's bloated Runtime class is being dismantled across four consecutive PRs, cutting the codebase from 3.5k lines to 550 and extracting the ESM loader as a standalone module.

OpenAI
McpToolCall migrations are complete — app-server now emits tool calls as canonical turn items instead of synthesizing them from deprecated legacy events, collapsing three separate changes into a unified dispatch and response model.

Anthropic
The Python SDK now lets you flush session writes on-demand instead of batching them until turn-end, unblocking near-real-time transcript persistence for production agents.

JAX updated its XLA dependency to a new compiler revision, surfacing potential performance shifts and optimization changes across the ML framework.

Meta
Jest is undergoing a comprehensive refactor to break apart its 3,000-line runtime class, while React DevTools patches a long-standing issue where component highlights persist when you move your mouse out of the inspector panel entirely.

OpenAI
A write-side timeout vulnerability in Codex websocket handling lets client requests sit indefinitely when the socket pump stalls, even after the server has already disconnected.

Anthropic
Two critical pre-release fixes landed overnight: buffa's doc validation pipeline now passes strict Rust warnings, and claude-code-action finally responds to @Claude with a capital C.

JAX shipped a flurry of optimizations and rollbacks overnight, addressing profiling bottlenecks and reverting experimental changes that didn't land.
read --wire →
Meta
Jest landed the feature engineers have asked for since ESM landed: you can now require() ES modules directly, no more dual-build nightmares.
read --wire →
OpenAI
Codex is shipping five architectural improvements tonight that lock down plugin reproducibility, add remote skill preview, and finally deprecate the legacy notify system that's been dead weight since the lifecycle hook engine took over.
read --wire →
Anthropic
The plugin validation pipeline now blocks contributor-controlled path inputs from reaching clone operations, closing a critical traversal vector that could have exposed the entire marketplace to malicious submissions.
read --wire →
Pallas TPU is simplifying its DMA synchronization model while Google Cloud Python draws a line at Django 3.2 and Python 3.9.

Meta
Jest can now require ESM modules directly [ref:7], and React Native patched a critical LayoutAnimation bug [ref:3] that's been crashing apps in production.
read --wire →
OpenAI
A critical Windows named-pipe ACL bypass in the elevated sandbox is patched [ref:1], while remote plugin bundle synchronization ships to keep installations in sync across backends [ref:2].

Anthropic
S&P Global and LSEG data connectors hit the marketplace in the same cycle while Claude Code v2.1.126 ships model discovery for compatible gateways.
