buildOne report1 publisher Next.js 16 stretches the default image cache from 60 seconds to 4 hours, so a replaced CMS image can serve stale all afternoon
Next.js 15 leaves Maintenance LTS on 21 October 2026, ending its scheduled critical bug fixes and security patches. A dev.to upgrade guide lists Next.js 16 defaults that compile cleanly and still change what users see, including image caching and route-change scrolling.

buildOne report1 publisher Prime Intellect's 2,000-agent Rust port of Prime Agent is benchmarked only on harness overhead
Prime Intellect says over 2,000 agents rewrote Prime Agent in Rust, using more than 10,000 sandboxes and 200 billion-plus tokens. Its speed and memory gains were measured with inference excluded, so they describe harness overhead and leave coding-task time untested.

buildOne report1 publisher Cloudflare adds on-demand production profiling for Workers and Durable Objects
Cloudflare now lets Workers and Durable Objects users take on-demand CPU and memory profiles in production and view them as flamegraphs. Each capture runs for a window the user sets and can be saved from the CLI to a .pprof file for further analysis.

buildOne report1 publisher Theo Browne's AI-written tsc-rs type-checks VS Code 13x faster than tsc 6
Theo Browne's AI-written Rust port of the TypeScript compiler type-checks VS Code 13x faster than tsc 6 and cost over $420,000 in tokens. Browne says he never read the code, so the 181,711 ported tests it passes are the main evidence that it behaves correctly.

buildOne report1 publisher Miro moved 70,000 tests from Jest to Vitest after years of slow CI, memory leaks, and failed patches
Miro moved 70,000 unit tests on its 6-million-line frontend from Jest to Vitest in two months, one of its engineers wrote. His figures for the old CI, six runners at up to 20 minutes a job, show what another team's test jobs would have to look like before the same switch pays off.

Redux Toolkit 2.13 adds TypeScript 7 support while holding its exported API steady
Redux Toolkit 2.13 adds official TypeScript 7 support and moves to a TSDown build, keeping its APIs unchanged from 2.12. The cost of upgrading is a TypeScript 5.6 floor plus bug fixes that change runtime results in edge cases.

buildOne report1 publisher Microsoft's Limbo tests catch AI agents duplicating writes in up to 74% of in-flight and redelivery faults
Microsoft researcher Jiapeng Li's Limbo benchmark found AI agents duplicated side-effecting writes in 56% and 74% of in-flight and double-delivery episodes. Offering idempotency keys cut duplicates from 28% to 4%, so tools that move money or send mail should require them.

OpenAI's Help Center says Memory in ChatGPT Space can write a user's personal context onto a shared page, where every viewer can read it. OpenAI's safeguard is a review before sharing, a check that runs once while collaborators' agents keep editing.

Transactional mail can pass SPF and DKIM and still fail DMARC when neither aligns with the visible From domain, a dev.to Node.js guide shows. Because forwarding breaks SPF, the author treats aligned DKIM as the path to protect.
