v0.2.1

Kana v0.2.1 sharpens session control and reliability with a new clean launch mode, per-session approval overrides, and smarter context handling.

Highlights

Clean launch mode

• Launch with --clean for a temporary session that touches nothing — no session files, no memory, discarded on exit.
• /skills, /mcp, /memory stay discoverable in clean mode but clearly report unavailability instead of failing silently.

Per-session tool approval

• /approval switches the current session between Always ask, Ask unless trusted, and Never ask (with a confirm step).
• The override applies only to the current session and resets on new/fork/resume or exit — nothing written to config or journals.

Smarter context and tool behavior

• Parallel tool calls are gated by model capability instead of being allowed blindly.
• Tool output is dynamically capped by remaining context to protect the budget near the limit.
• Reasoning effort shows in the TUI status line; unsupported Codex ultra effort removed.
• Bash timeout ceiling raised; buffered TUI text renders before tool results.

Also included

• Harbor evaluation adapter with proxied evaluation support.
• Clean-session and rendering reliability fixes.
