Tools official 2 src. ~1 min

Anthropic shipped Claude Code v2.1.232 on 2026-08-13, turning on subagent forking by default (fork-type subagents inherit the full conversation and prompt cache), adding @-mention cross-session messaging via SendMessage, and extending plugin marketplaces to GitLab repos with matching secret redaction. The release also fixes several permission-bypass bugs on Windows/PowerShell and hardens the Linux sandbox.

Why it matters

Default subagent forking and cross-session messaging change how multi-agent Claude Code workflows share context and communicate, and the fixed permission bypasses are meaningful security hardening.

Importance: 2/5

Notable update: minor version with real agentic and security changes, official source only.
