-
-## 2026.1.11-5
-
-### Fixes
-- Auto-reply: prevent duplicate /status replies (including /usage alias) and add tests for inline + standalone cases.

-
-### Fixes
-- CLI: read the git commit hash from the package root so npm installs show it.
-

-
-### Fixes
-- CLI: avoid top-level await warnings in the entrypoint on fresh installs.

-
-### Fixes
-- Installer: ensure the CLI entrypoint is executable after npm installs.

-## 2026.1.11-1
-
-### Fixes
-- Installer: include `patches/` in the npm package so postinstall patching works for npm/bun installs.
+- Cron: add optional `agentId` binding (CLI `--agent` / `--clear-agent`), route cron runs + summaries to the chosen agent, and document/test the fallback to the default agent. (#770)
