Vercel/Chat pulled the Slack direct WebClient access feature after discovering it silently dropped custom API URLs, while Next.js canary lands 41-second CI wins across test workflows.

The Slack adapter revert [1] undoes a feature that exposed the underlying @slack/web-api WebClient for direct API calls [2], but the implementation had a critical flaw: `createSlackAdapter()` was dropping the `apiUrl` config field entirely, breaking GovSlack and other custom Slack deployments [3]. This is a good catch—the pattern mirrors Linear and GitHub adapters, but shipping broken config handling is worse than shipping nothing. Meanwhile, Next.js canary.18 [4] landed incremental wins: restored pnpm store caching and eliminated redundant Playwright installs across steps [5], cutting 41 seconds from CI pipelines that don't need browser testing. The core changes also remove redundant instant navigation prefetch headers [4] and improve error reporting in Instant Insights. Over in Turborepo, the team shipped v2.9.12 [6] while quietly restoring the mobile docs menu that broke navigation on narrow widths [7]. Vercel's CLI and build packages all bumped with dependency updates [8][9][10][11][12]—nothing earth-shattering, but Python tooling gained service type metadata in the project manifest [12]. Workflow SDK cleaned up the instrumentation stub in the workbench [13], aligning testing with actual getting-started guidance.

Action items

→ Review any custom Slack API URL configs—they were silently ignored until v1 ships the fix vercel/chat [immediate]
→ Pull Next.js canary.18 in dev environments to validate CI speedups before stable release vercel/next.js [plan]
→ Monitor Turborepo v2.9.12 for versioned docs issues—release flagged aliasing failures in automation vercel/turborepo [monitor]
