A weekly digest of what changed in 30 developer tools, classified by severity, so you catch the breaking changes before your next deploy.
Severity is always color plus a shape plus the word, never color alone. Open a tier to see the real thing from Issue #1.
A breaking change in a stable release, a security fix, or a forced migration, proven by a verbatim quote from the release notes. The only tier with a "Do this:" action box. Read it before your next deploy.
A bug in @liveblocks/client could cause data loss by overwriting room storage when large WebSocket messages are sent.
Do this: update to @ai-sdk/provider-utils@5.0.4 immediately.
Worth knowing, new capabilities, meaningful features, or non-forced migrations you will want on your radar. Nothing that breaks on deploy.
Patches, dependency bumps, and prereleases, collapsed into a single count so the signal stays clean. Prereleases are capped here in code and cannot be inflated.
+224 patches, dependency bumps, and prereleases in Issue #1, folded into one line so you can skip them with a clear conscience.
The pipeline pulls new releases from 30 GitHub repos every day, patches to major versions, nothing skipped.
Claude grades each release CRITICAL / NOTABLE / FYI. Every CRITICAL needs a verbatim quote from the notes; prereleases cap at FYI.
A second AI editor re-reviews every classification each week; corrections are validated and applied, and the rubric is amended when a pattern repeats.

Watching 30 repos is 30 noise streams with no triage, 8 Clerk packages bumping the same day, 6 Cloudflare Workers SDK releases in a week, and no signal about which ones actually break your app. StackTrace reads all of them and grades each against a public rubric, so you get the 1 thing that matters, not 100 things that don't.
The rubric is deterministic and conservative: CRITICAL requires a breaking change in a stable release, a security fix, or a forced migration, and a verbatim quote from the release notes proving it. Prereleases are capped at FYI in code, and any issue with more than 4 CRITICALs is automatically held for review. Ties go to the lower tier. We never promote to fill a slot.
The classification uses Claude, but it runs inside code-enforced guardrails: ungrounded CRITICALs are rejected before an issue can ship, prereleases can't be inflated, and a second AI editor re-reviews every classification each week. The rubric is public, you can read the exact instructions the model gets.
