Faster Auto model · Safer signup · More resilient tasks

Models
- Auto now defaults to DeepSeek V4 Flash for faster everyday work, and the model is also available for manual selection.
Tasks and chat
- Tasks now preserve context more reliably across runtime changes, long conversations, provider failures, and explicit stops before the first response appears.
Account security
- Email signup now requires both an image challenge and Cloudflare Turnstile, while improved device checks reduce false-positive reward holds and slow security checks no longer show a premature failure warning.
Mobile sign-in
- Google sign-in on mobile can now recover from transient callback network failures without losing the login attempt.
Files
- Downloads from connected storage now preserve filenames safely, including names with spaces and special characters.
