v2.6

## Agent Zero Release Notes

- **Consolidated goal tool** — Replaced the separate create, get, update, and storage modules with a single multi-action goal tool while preserving the slash command, API, goal strip, and active-goal response behavior.

- **Resumable, secret-safe chat compaction** — Compaction now preserves authorization, evidence, pending work, loaded skills, and secret references in a fixed resumable-state summary. The stale context-window cache is cleared after compaction.

- **Smarter runtime secret redaction** — Masking of `usr/.env` values is now limited to API keys and login/password credentials, preventing ordinary settings from corrupting chat text. Global and project secrets remain fully protected.

- **Shell and SSH process exits handled as completion** — Terminated local, SSH, and TTY shells are now detected and treated as definitive command completion. New `is_terminated` and `get_exit_code` helpers are available across session types. Terminated sessions are recreated lazily before the next command.

- **Deferred task resource cleanup** — Callables and arguments are now released after task completion or cancellation, preventing retained references. Child tasks are cleaned up and best-effort destructors added for local and SSH sessions.

- **Paramiko import traceback leak fixed** — Cleared a stale traceback retained by Paramiko's optional-import cache that was keeping the code-execution tool-loading stack and first agent in memory.

- **Chrome Web Store extension installs fixed** — Redundant same-version reinstalls are skipped, updates are staged before replacing files, and active browser runtimes are restarted safely.

- **Stabilized internal Docker browser rendering** — WebUI navigation now returns after the initial document commit, socket timeouts align with browser command deadlines, and cropped or mismatched screencast frames are rejected to prevent viewport stretching.

- **Inline confirmation for extension deletion** — The native confirm dialog is replaced with the shared inline confirmation UI, with proper escaping of extension names.

- **Page-tail history snapshots for connectors** — Interactive clients can now receive a bounded tail snapshot and cursor-based older pages. Clients that do not request history hints still receive complete replay.

- **Hardened malformed response and tool handling** — Missing or malformed response arguments now raise a repairable exception instead of exposing a `KeyError`. Fenced or structurally broken tool intent is routed through the existing misformat repair path so streamed chats no longer stall in a thinking state.

- **Stabilized WebUI mount geometry** — Added responsive shell styling with a 250 px desktop sidebar that yields to the mounted left panel and collapses on mobile. The welcome composer now reserves its final height during hydration.

- **Launcher download links updated to v1.4** — README and platform installer links now point to the published v1.4 Launcher artifacts.
