Supabase fixes broken client trace propagation and now preserves trace IDs even for unsampled requests

supabase-js 2.112.3 materially improves the tracing rollout BTN covered earlier: unsampled requests now still carry traceparent for backend log correlation, tracing misconfiguration produces warnings, and browser Edge Function calls need current CORS headers to admit W3C trace context.

GitHub Spark is shutting down August 31 — export code now and replace broken `llm()` calls

GitHub Spark stops being available to existing users on August 31, 2026. Deployed apps are meant to keep running, but owners should export code to a repository now; Spark apps using `llm()` need a separate inference provider because the underlying GitHub Models service retired July 30.

Cloudflare Workers now enables Node.js compatibility by default for new compatibility dates

Cloudflare has inverted a long-standing Workers assumption: Node.js compatibility is now on by default for current compatibility dates. That reduces setup friction for many npm packages, but it also means developers need to understand compatibility-date boundaries, partial APIs and explicit opt-out flags.

Cloudflare raises the stateful Dynamic Worker concurrency ceiling from four to ten

The new 10-worker ceiling is a niche but concrete scaling change for platforms using Cloudflare Dynamic Workers as agent code sandboxes, generated-app runtimes or multi-tenant automation workers. Ordinary Worker requests remain capped at four distinct Dynamic Workers in flight.

Its v0.2 developer preview can bind model, policy, data and tool-use claims to confidential-computing attestation, but it is still pre-ratification and explicitly not ready to treat as a production compliance guarantee.
