What has changed since

An entry is only as true as the day it was written.

Flags move on the server after a release ships. Anthropic's own notes land days later and their documentation later still. Sometimes an entry turns out to be wrong and gets corrected by hand. All of that is recorded against the entry it happened to, and this is the whole of it in the order it happened.

Nothing here replaces an entry. Every line links to the page its release published, still saying what that release said, because a correction is added and dated rather than swapped in.

the line in the docs

| `permissionDecision` | `"allow"` skips the permission prompt, except for the [actions no mode auto-approves](/docs/en/permission-modes#actions-no-mode-auto-approves), for [reads from network paths](/docs/en/permissions#network-paths), an…

v2.1.281permissions.allow Documentation arrivedA small documentation edit on Run Claude Code programmatically touched a line naming permissions.allow after this was published.
the line in the docs

* **`dontAsk`**: Claude Code denies every call that would otherwise prompt, which is useful for locked-down CI runs. Actions that need no approval in Manual mode still run, such as file reads in your working directories and the [read-only …

v2.1.293bypassPermissions Documentation arrivedAnthropic's documentation has since written up bypassPermissions, on Configure permissions.
the line in the docs

Coverage depends on the entry's form: a bare name like `Read` or `mcp__github__get_issue` auto-approves every call to that tool apart from those exceptions and [reads from network paths](/docs/en/permissions#network-paths), while a scoped …

v2.1.288permissionDecision Documentation arrivedA small documentation edit on Intercept and control agent behavior with hooks touched a line naming permissionDecision after this was published.
the line in the docs
