Subject: [PATCH 01/17] Add Turkish interface language
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a complete Turkish (tr) message catalog and register tr as a
supported interface locale and native language across the frontend
and backend: locale lists, browser-language detection, registration,
settings and admin selectors, schema validation, voice session titles,
lesson feedback, and transactional email templates.

Turkish capitalizes language names, so tr is added to the
capitalization set in formatLanguageName (lowercasing would also turn
"İ" into a dotted "i̇").

The dashboard announcement keeps its existing ten stored locales;
Turkish users fall back to the English translation.

 ## [Unreleased]
 
+### Added
+
+- Turkish (`tr`) interface language: full interface translation, Turkish as a native-language option at registration and in Settings, and Turkish verification, password reset, welcome, and account deletion emails. The dashboard announcement keeps its existing ten locales and falls back to English for Turkish users.
+
 ### Fixed
 
 - Onboarding learning goals now name the selected language in all ten interface languages, with natural wording and a safe display fallback for unrecognized language codes.

 - **POST `/me/avatar`** — Rate limit: 60/min. Uploads the authenticated user's profile avatar (JPEG/PNG, max 2 MB). Validates the declared content type, image signature, and minimal image structure, stores the image on disk under `/app/avatars` using a non-predictable UUID filename, and returns the user profile with `avatar` set to a cache-busted internal reference (`/api/avatars/{uuid}.{ext}?v={ms}`). The file reference is not publicly served.
 - **GET `/me/avatar-file`** — Rate limit: 60/min. Authenticated current-user avatar retrieval endpoint. Returns only the authenticated user's own avatar file; this is the supported image retrieval path used by the frontend. Responses are marked `Cache-Control: private, no-store`; client-side avatar reuse is handled by the frontend blob cache keyed by the stored avatar reference.
 - **DELETE `/me/avatar`** — Rate limit: 60/min. Removes profile avatar (sets to null)

+## [1.9.25] - Unreleased
 
 ### Added
 
-- Turkish (`tr`) interface language: full interface translation, Turkish as a native-language option at registration and in Settings, and Turkish verification, password reset, welcome, and account deletion emails. The dashboard announcement keeps its existing ten locales and falls back to English for Turkish users.
+- Turkish (`tr`) interface language and native-language option in registration, Settings, and administration, including localized learning feedback, voice-session titles, and transactional emails.
+- Dashboard announcements support Turkish as a source and translation language, alongside the existing ten languages.
+
+### Changed
+
+- Existing dashboard announcements remain readable with ten translations; adding Turkish is required before saving them again and creates a new announcement revision.
+- What's New now highlights the Turkish interface and retains the general fixes note in all eleven interface languages.

Subject: [PATCH 03/17] Localize UI labels and defer review prompt form
 rendering

- Replace hardcoded tooltips, aria labels, and sr-only text with locale strings across chat, feedback, flashcards, phrasebook, layout, loading, landing nav, sheet, and word tooltip components
- Add missing translation keys for delete, menu open/close, voice session, copy phrase, and vote actions in all supported locales
- Update assistant avatar alt text from Tutor to Lingu in chat and transcript components
- Start review prompt in a checking state, reset it when closed, and wait for the existing-review lookup before showing the rating form
- Extend frontend tests to cover localized labels, vote toggle label updates, loading-state behavior, and translated close labels
- Document localized tooltip and accessibility text behavior in frontend architecture specs and review prompt flow in review specs
- Record the fixes in the changelog

 ### Changed
 
-- Existing dashboard announcements with ten, eleven, or twelve translations remain readable; a new save requires all thirteen, and adding a missing language creates a new announcement revision.
-- What's New announces five interface languages (Croatian, Danish, Finnish, Swedish, and Turkish) in alphabetical order for each of the thirteen current interface locales, alongside the general fixes note.

 ### Changed
 
-- Existing dashboard announcements with ten through fourteen translations remain readable; a new save requires all fifteen, and adding a missing language creates a new announcement revision.
-- What's New announces five interface languages (Croatian, Danish, Finnish, Swedish, and Turkish) in alphabetical order for each of the fifteen current interface locales, alongside the general fixes note.

-### Fixed
-
-- Tooltips and accessible control labels for chat, vocabulary, phrasebook, feedback, navigation, loading, and shared panels now follow the selected interface language.
-- The review prompt waits for the existing-review check before showing the rating form, preventing early rating selections from being lost.
-- Grammar, vocabulary, and phrasebook help now show the user's native-language name for every supported profile language, including the five new options.
-- Voice conversation dates use the correct day punctuation in Danish and Finnish.
-- Dutch, Polish, Romanian, and Russian FAQ answers now explain that public registration is disabled by default.
+- Dashboard announcements with ten through fourteen translations remain readable; saving requires all fifteen and completing a translation creates a new revision. The editor loads the chosen source language's text before translating.
+- What's New presents the five interface languages (Croatian, Danish, Finnish, Swedish, and Turkish) in each of the fifteen interface locales alongside a general improvements note.
+- Interface text, resource counts, accessible controls, errors, administrator badges, dates, numbers, and prices follow the selected interface language. Study help displays the user's native-language name, and voice-session dates follow native-language conventions.
+- The review prompt waits for the existing-review lookup before showing the rating form. The Dutch, Polish, Romanian, and Russian FAQs explain the default public-registration setting.

Subject: [PATCH 14/17] Improve locale handling and voice message localization

- Pass the selected locale into email template rendering and set HTML lang accordingly
- Update transactional email tests to verify rendered locale declarations
- Sync locale cookies on profile save and reload only when the displayed locale changes
- Enforce 10-25 character password length on reset and surface requirements in the UI
- Localize conversation error codes and hide backend transport diagnostics from users
- Add translated voice trial and speech error strings across supported locales
- Fix Croatian comment pluralization and extend plural coverage tests
- Update password reset and voice message localization tests to cover the new behavior

@@ -18,6 +18,15 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/)
 - Interface text, resource counts, accessible controls, payment-recovery and error messages, administrator badges, review ratings, learning-language names, dates, numbers, and prices follow the selected interface language. Study help displays the user's native-language name, and voice-session dates follow native-language conventions.
 - The review prompt waits for the existing-review lookup before showing the rating form. The Dutch, Polish, Romanian, and Russian FAQs explain the default public-registration setting.
 
+### Fixed
+
+- Saving the interface language synchronizes locale cookies and applies the selection when the displayed language differs, including when that selection was already saved in the profile.
+- Post-assessment voice-trial prompts and Premium continuation messages are translated in French, Portuguese, German, Italian, Polish, Dutch, Romanian, and Russian.
+- Voice transcription, tutor-response, speech-generation, and transport errors display localized messages instead of raw backend or WebSocket diagnostics.
+- Croatian feedback comment counts use the correct plural forms, including counts such as 21 and 31.
+- Password reset displays the current password requirements and validates the 10-25 character length consistently with the backend, with translated errors across all fifteen interface locales.
+- Transactional emails declare the language of their rendered content in HTML, including the English fallback for unsupported locales.
+
 ## [1.9.20] - 2026-09-24

 - Saving the interface language synchronizes locale cookies and applies the selection when the displayed language differs, including when that selection was already saved in the profile.
+- Initial locale detection preserves an existing supported interface-language cookie and ignores `Accept-Language` entries with zero or out-of-range quality weights.
 - Post-assessment voice-trial prompts and Premium continuation messages are translated in French, Portuguese, German, Italian, Polish, Dutch, Romanian, and Russian.
 - Voice transcription, tutor-response, speech-generation, and transport errors display localized messages instead of raw backend or WebSocket diagnostics.
 - Croatian feedback comment counts use the correct plural forms, including counts such as 21 and 31.
