Product updates and release notes for FlashTranslate.Net.

v0.3.5

October 23, 2026

Added an About page in extension settings with the installed version, changelog, documentation, support and legal links, and searchable third-party open-source licenses.
Selection, full-page, and YouTube subtitle translation buttons now show a distinct unavailable icon when no LLM configuration can be used or your sign-in session needs attention.

Unavailable translation buttons now explain the issue and provide a direct route to LLM setup or sign-in. YouTube’s original captions remain available when subtitle translation cannot start.

October 10, 2026

Fixed an issue that could require signing in again after reopening the browser.
Signing out in Chrome or Edge now keeps the same account signed in on the other browser.

October 9, 2026

Added Microsoft Edge support alongside Chrome.
Added LLM setup templates for DeepSeek, Qwen, Kimi, and SiliconFlow, with a smoother default flow for Chinese users.
Added provider dashboard links during LLM setup.
Added a default settings page option, so opening the extension can take you directly to General, LLM Providers, or the Dashboard.

Improved sign-in and cloud sync handling so guest configurations are preserved more reliably after logging in.
Fixed cases where newly merged guest configurations could overwrite an existing cloud default.

September 16, 2026

Translation panels now display more reliably on sites with custom dark themes. Full-page settings, selection translation, subtitle settings, and model menus keep their intended background instead of appearing transparent.

September 15, 2026

When your session expires, selection, full-page, and YouTube subtitle translation now provide clearer sign-in recovery actions that take you back to the extension settings.
YouTube subtitle translation can now keep a visible sign-in reminder and resume translation after you sign in again.
LLM configurations that belong to another account are now locked more clearly, with private details hidden while still allowing local-only cleanup.
Translation reliability controls now include request timeouts, separate retry budgets for network errors and response-format errors, and a success-rate chart in the usage dashboard.
Google Gemini translation now uses Gemini’s native structured output mode, improving reliability for selection, full-page, and subtitle translation.

YouTube subtitle menus and sign-in prompts now recover when the player replaces its UI nodes during navigation or playback changes.
Full-page translation retries now clean up partial batch results before trying again, avoiding duplicate or stale translated blocks after response-format errors.

August 28, 2026

FlashTranslate now uses clearer localized names that highlight AI-powered web and YouTube translation.
Full-page and YouTube subtitle translations now include limited page or video context, helping preserve the meaning of titles, topics, and proper names.
Automatic YouTube subtitle segmentation now adapts to the source subtitle language for German, English, Spanish, French, Japanese, Korean, and Russian.

Full-page and YouTube subtitle translations now display correctly when Gemini returns supported structured response wrappers or JSON code fences.
YouTube subtitle overlays now refresh as soon as a translation for the current subtitle arrives.

August 9, 2026

Signing back in after an expired session now restores all of your cloud-stored LLM configurations.
Your cloud configurations now replace stale local configurations left over from a different account or environment.

Deleting a configuration now syncs reliably across your devices, so deleted configurations do not reappear after a later sync.

August 8, 2026

Removed the unnecessary tabs permission. FlashTranslate.Net now requests only the browser permissions needed for its current features.

The first-install experience and background session refresh continue to work as before.
This release does not change the extension’s user-facing translation features.
