v2.1.4

Long agent runs no longer silently forget how they started — when prior chat history overflows the context budget, the dropped older messages are summarized instead of just truncated. Plus a command-whitelist hardening.

Security

• Inline code execution is blocked in agent mode. The command whitelist
  allowed interpreters like node/python/php, but their eval flags
  (node -e, python -c, php -r, deno eval, …) turned a whitelisted
  runtime into arbitrary code execution. Those flags are now rejected (including
  combined short clusters like -pe). Running a file (node app.js,
  python script.py) is unaffected. Defense-in-depth — the manual-mode
  permission prompt is still the primary gate.

Added

• Auto-summarized history. When the prior conversation exceeds the agent's
  context budget, Codeep now condenses the dropped (oldest) messages into a
  short recap — preserving early decisions, constraints, and unfinished threads
  — and injects it before the recent verbatim history. Previously those older
  messages were silently truncated. The recap is one cheap LLM call, made only
  on overflow and cached per session. Opt out with
  autoSummarizeHistory: false (falls back to plain truncation, no extra call).
