What is new in Yardlet 0.11.11

# Yardlet 0.11.11

This release fixes two security issues in 0.11.10. Please update.

## Security

- Filling a saved sign-in now asks you first on more of the pages an agent's script may still reach, including pages
 that tabs linked to it open or load later.
- Each saved connector secret is now tied to the server, mail account, program or account provider it was saved for,
 and is used only there. Secrets saved before keep working without a new sign-in.
- Signing in to a connector's server checks that the sign-in details the server publishes name that same server.

## Tasks

- Turns cut off by a force quit, a crash or a killed process now continue at the next launch, as after a quit.
- The task list shows at launch without waiting for every Claude Code title to be read again.
- Opening a main window again, from the Dock or with File › New Window, no longer interrupts running tasks.
- Launching with a long Codex history no longer keeps Codex busy for half a minute: Yardlet lists Codex threads from
 Codex's own database, as the Codex app does.
- Agent CLIs installed with Homebrew now update automatically. After a CLI updates, idle tasks start the new version
 with their next message.
- Automatic account choices skip accounts whose plan doesn't offer the task's model.
- Messages sent while a task waits to switch accounts no longer stay queued behind a background command.
