99 <div>Hooks can now call MCP tools directly via <a href="/docs/en/hooks#mcp-tool-hook-fields"><code>type: "mcp\_tool"</code></a>, so a hook can hit an already-connected server without spawning a process</div>

100 <div><code>/cost</code> and <code>/stats</code> are merged into <a href="/docs/en/commands"><code>/usage</code></a>; the old names still work as typing shortcuts that open the relevant tab</div>

101 <div><code>/config</code> changes (theme, editor mode, verbose, and similar) now persist to <code>\~/.claude/settings.json</code> and follow the same project/local/policy precedence as other <a href="/docs/en/settings">settings</a></div>

102 <div><a href="/docs/en/sub-agents#fork-the-current-conversation">Forked subagents</a> can be enabled on external builds with <code>CLAUDE\_CODE\_FORK\_SUBAGENT=1</code>: a fork inherits your full conversation context instead of starting fresh</div>

105 <div><code>--from-pr</code> now accepts GitLab merge request, Bitbucket pull request, and GitHub Enterprise PR URLs in addition to github.com</div>

106 <div>Auto mode: include <code>"\$defaults"</code> in <a href="/docs/en/auto-mode-config"><code>autoMode.allow</code>, <code>soft\_deny</code>, or <code>environment</code></a> to add custom rules alongside the built-in list instead of replacing it</div>

107 <div>New <a href="/docs/en/plugin-dependencies#tag-plugin-releases-for-version-resolution"><code>claude plugin tag</code></a> command creates release git tags for plugins with version validation</div>

108 <div>Opus 4.7 sessions now compute against the model's native 1M context window, fixing inflated <code>/context</code> percentages and premature autocompaction</div>
