Sunday ran quiet: no Anthropic releases in the 24-hour window.
No tags, no announcements, no notes. The window from Saturday 9 PM to Sunday 9 PM ET produced no output from any source in the sweep. Here is where each one sat when the window closed.
v2.1.143, 2026-05-15 22:28 UTC. Plugin dependency enforcement: claude plugin disable now refuses when another enabled plugin depends on the target, with a copy-pasteable disable-chain hint. claude plugin enable force-enables transitive dependencies. PowerShell tool now passes -ExecutionPolicy Bypass by default (opt out via CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY=1). Background sessions preserve model and effort level after waking from idle. Added worktree.bgIsolation: "none" for repos where worktrees are impractical. Fixed corrupt .credentials.json hanging CLI on startup, stop hooks looping forever (ends after 8 consecutive blocks), and a wide set of agent view and Windows Terminal issues. Nothing since.
v0.102.0, 2026-05-13. Added BetaManagedAgentsSearchResultBlock types and cache diagnostics beta support. Nothing since.
