Released Jul 24, 2026. Everything the community has pinned to this exact release.
Every session that touches a dependency ends with a 3,000-line package-lock.json diff, even when I asked for a one-line version bump. Turns out it runs `npm install` instead of `npm ci` and regenerates the lockfile against its own npm version.
Asking for a whole file back — a long migration, a generated fixture, a full rewrite — fails outright instead of truncating. The fix is to stop asking for one enormous message.
Claude Code can't see Xcode's build errors unless you hand them over. XcodeBuild MCP plus a formatter that strips the noise gives the agent a real edit-build-test loop for SwiftUI work — the difference between guessing and iterating.
Five days, two agents, one working Stripe billing portal: what was delegated, what broke, what it cost ($61.40 all-in), and the day everything went sideways.
