Claude Code — Changes

7 November 2026 · v2.1.319

17 August 2026 · v2.1.233

+`claude self-hosted-runner` — turn your own machines/containers into a place Claude Code web, mobile, and desktop sessions can run

+`--environment` — run a new cloud session on a specific self-hosted environment

+`/list-agents` (alias `/peers`) — list subagents and other live sessions you can message

+`Ctrl+S` — stash/restore the prompt draft outside the reverse-search dialog

+Fork mode — `subagent_type: "fork"` on by default in interactive sessions: inherits the full conversation + prompt cache, and non-fork spawns also default to background

~`--worktree`/`-w` — accepts GitLab merge request URLs, not just GitHub PRs

~`claude ultrareview` — `--post` posts findings to a `github.com` PR as a comment

+`:` emoji shortcode — type `:heart:` to insert, disable with `emojiCompletionEnabled`

+`/autocompact`, `--autocompact` — set the auto-compact window without touching saved settings

+`DirectoryAdded` hook — fires after `/add-dir` or an SDK `register_repo_root` call

+`background: false` skill frontmatter — with `context: fork`, wait for the result instead of backgrounding it

~`/code-review` — now runs as a background subagent so it doesn't fill your conversation; omitting the level reuses your last pick

~`/status` — now shows session kind (`interactive` vs. background job `attached`/`unattended`)

~`/fork` — the copy now creates its own git worktree before editing code, unless it edits in place

~`/background` — background sessions now commit and push as they go, open a draft PR only when warranted, and report where the work lives

~Subagent nesting depth — default raised to 3 layers (was 1); concurrent cap of 20 and per-session cap of 200 documented alongside it

~`--mcp-config` — in `-p` mode, Claude Code now waits for servers to connect before the first turn

~`--max-budget-usd` — subagent spend now counts toward the cap; reaching it blocks new spawns and halts running background subagents

19 July 2026 · v2.1.215

~`/code-review`, `/verify` — Claude no longer runs these on its own; invoke them directly when you want them

18 July 2026 · v2.1.214

+`claude auto-mode reset` — restore auto mode to its default configuration

+`/subtask` — background subagent that inherits the full conversation and reports back (what `/fork` used to do)

+`--forward-subagent-text` — stream subagent text/thinking blocks in stream-json output

+`--ax-screen-reader` — flat-text rendering for screen readers

~`/fork` — now copies the conversation into an independent background session instead of reporting back; the old report-back behavior moved to `/subtask`

~`/btw` — question is now optional; reopens your last side question's answer when omitted

~`/advisor`, `--advisor` — Fable 5 is no longer offered as advisor

~`claude auto-mode defaults` — documented `--label` filter and the companion `claude auto-mode config` subcommand

11 July 2026 · v2.1.207
