Version 2.3.10 Highlights & Improvements:

• Hardened Google Translate Resilience: Migrated to the modern translate-pa.googleapis.com endpoint explicitly authorizing Mozilla extensions, resolving 429 rate-limiting and Captcha challenges.
• Automatic Resilient Fallback: Seamless automatic switch to the free MyMemory service if Google Translate ever encounters rate limits or network issues.
• New MyMemory Provider: Built-in free translation without any API key required with smart sentence chunking (5,000 chars/day per IP, expandable to 50,000 chars/day with an optional email address).
• Compose Mode Hardening: Clear alert when neither Subject nor Body is checked (no more false successes), and immediate error propagation if body translation fails.

Version 2.3.9 Highlights & Improvements:

• Universal Custom Server Support: Re-enabled on-demand dynamic host authorization for any custom or self-hosted OpenAI-compatible endpoint (DeepSeek, OpenRouter, Claude proxies, private VPS, corporate gateways).
• Seamless 1-Click Authorization: Host permission requests trigger strictly on direct user clicks with native Thunderbird confirmation dialogs.
• Full Control & Reversibility: Each authorized domain automatically gets its own dedicated toggle switch in Thunderbird's Add-ons Manager and can be revoked at any time in 1 click.
• Hardened Stability: Strict WebExtension host match pattern compliance and eliminated background warnings.
