Stable moved seven times in small steps, once about a day after publish; it now serves 2.1.287. Stable stopped behaving like the parent window’s freeze-and-jump pointer: it moved seven times in 16 days, one to six versions at a time, and six of the seven promotions came 7.2 to 10.1 days after npm publish, which matches the documented “about one week old”. The exception: 2.1.285 reached stable about 26 hours after publish, replacing 2.1.280 after one day, and it carried the auto-mode starting-mode changes, the OS-denied managed-settings exception and allowedProviders. 2.1.278, the server-side classifier default, was never a stable build; stable got that default with 2.1.280 on 2026-09-29. At the 2026-10-13 observation stable serves 2.1.287, with mods on by default, while latest and next serve 2.1.296. Npm, native vendor pointers and Homebrew agree. All 17 in-window GitHub releases are non-prerelease; there is no separate preview or beta channel. Stable lacks 2.1.288 through 2.1.296. The native installer defaults to latest; npm installs as npm install -g @anthropic-ai/claude-code, and Homebrew casks claude-code and claude-code@latest select stable and latest respectively.

Channel: tagged-release (the stable-channel pointer); docs-only (channel wording). Half: both. Date: 2026-09-23 to 2026-10-09.

Operator consequence: Stable is now roughly a one-week lag with fast-tracks, not a guaranteed soak: a build that changed the starting permission mode reached it in a day. Keep minimumVersion or managed requiredMinimumVersion pinned to the fix you need, and read the changelog of the build stable moves to, not the one a week back. The apt stable index records which builds stable served; pool upload times and Homebrew bumps bound approximate promotion times rather than proving an exact dist-tag history. Use both when dating exposure windows.
