Changelog

v3.4.5 (2026-04-11)

Runtime UI Translation (CDN deliverable)

Widget static labels now retranslate when a student switches language inside the drawer. Previously, every mustache {{#str}} lookup in chat_widget.mustache rendered once at page load in the Moodle user's language and stayed frozen. Switching language from the settings panel only updated the input placeholder and conversation starters; bottom tabs (Chat/Voice/Notes), voice panel title and copy, history panel, header tooltips, footer buttons, and LLM picker labels all stayed English.
Added amd/src/i18n_strings.js: a bundled 46 language translation table for every static widget string. Missing keys fall back to English.
chat.js now tags the widget DOM with data-i18n-* attributes at init time and applies the current language immediately. The same pass fires on every language switch in both the compact language picker and the in drawer settings panel.
The fix ships via the CDN bundle (sola.min.js), so Saylor production running v3.4.4 picks up runtime translation on the next cdn_version bump without a plugin reinstall.
Covers: bottom tab labels, voice mode card (title, copy, ready status, start/end labels), Notes/History panel (title, subtitle, Saved/Recent views, empty states), header action tooltips (change avatar, settings, clear, reset, close), language suggestion banner, starters container aria label, footer Usability Testing and Feedback buttons, LLM picker labels, mic and send buttons, input placeholder.

Admin Rebranding for Upstream Usability

Removed the "SOLA:" prefix from every admin page display name so other institutions can use the plugin without Saylor-specific branding in the admin tree. The 7 settings pages now show as General, AI Provider & Models, Content & RAG, Safety & Moderation, Engagement, Branding & UI, Integrations & Delivery. The 4 external tool pages show as Survey Editor, Usability Testing Editor, Rubric Editor, WhatsApp Integration Test.
The top level admin category is now titled "AI Course Assistant" (from get_string('pluginname', ...)) instead of "SOLA (AI Course Assistant)". Student facing branding in the widget header still respects the short_name admin setting, which defaults to "SOLA" for Saylor and can be overridden per install.
Stable section identifiers (local_ai_course_assistant_general, etc.) are unchanged. URLs, bookmarks, and the self-updater all keep working.

Bug Fixes

Section error when clicking Global AI Settings from the wrench icon or Back to Settings links. The v3.4.4 settings restructure replaced the single local_ai_course_assistant admin settings page with a category of the same name containing 7 admin_settingpage children. 9 PHP admin pages still linked to the old /admin/settings.php?section=local_ai_course_assistant URL, which no longer resolves to an admin node and throws error/admin/sectionerror. Updated every link to /admin/category.php?category=local_ai_course_assistant instead, which lands on the plugin category page showing all 7 sub pages. Affected files: course_settings.php, rag_admin.php, update_admin.php, analytics.php, usertesting_admin.php, rubric_admin.php, survey_admin.php, integrity_admin.php, starter_settings.php.
Defensive registration of Catalyst's WhatsApp Integration Test admin page. Catalyst's fork adds whatsapp_test.php which calls admin_externalpage_setup('local_ai_course_assistant_whatsapptest'). The v3.4.4 settings restructure wiped that registration when Catalyst merged it, causing error/admin/sectionerror on their staging. settings.php now registers the page conditional on file_exists(whatsapp_test.php), so upstream installs without the file build a valid admin menu while Catalyst's fork works without a local patch.

Claude API: Adaptive Thinking

Adaptive thinking support for Claude models. When enabled via the new "Extended Thinking (Claude only)" admin toggle (AI Provider & Models page), SOLA sends thinking: {type: "adaptive"} to the Anthropic API. Claude decides when and how much to reason through a problem before answering. Thinking content is filtered out of the student facing response (streaming and non streaming). Temperature is forced to 1 when thinking is active (API requirement). Other providers ignore the setting.
Minimum max_tokens raised to 8192 when thinking is on to provide headroom for reasoning tokens.

Claude API: Prompt Caching

System prompt now uses Anthropic prompt caching. The system prompt is sent as a structured array with cache_control: {type: "ephemeral"} instead of a plain string. This enables server side prefix caching across all requests in the same course. Previously, every SSE chat request paid full input token cost for the system prompt even though the text was identical across users.
Token usage now captures cache_creation_input_tokens and cache_read_input_tokens from both streaming and non streaming responses, surfaced in get_last_token_usage().
Beta header prompt-caching-2024-07-31 included automatically.

Structured Outputs for Quiz Generation

Quiz generation now uses provider native structured output instead of relying solely on <quiz>JSON</quiz> delimiter prompting. For Claude, this uses the tool_use pattern with a forced tool_choice. For OpenAI compatible providers (OpenAI, Gemini, DeepSeek), this uses response_format: {type: "json_schema"}.
Response parsing cascades: structured JSON first, then <quiz> regex fallback, then raw JSON. Backward compatible with providers that do not support structured output (Ollama, Groq, etc.).
New get_quiz_json_schema() method defines the canonical quiz schema with additionalProperties: false for strict validation.

Provider Fixes

Ollama endpoint changed from /api/chat to /v1/chat/completions (the OpenAI compatibility layer). The native /api/chat uses NDJSON streaming, which is incompatible with the SSE parser in openai_compatible_provider. This was a latent streaming bug: Ollama chat would silently fail or produce no output.

Tooling

deploy_dev.py now accepts --target {dev,405,500,501,all}. Default stays dev (dev.sylr.org). --target all deploys to dev, dev405, dev500, and dev501 in sequence with a single tarball and S3 upload. The tarball is extracted into a per target scratch dir so parallel rsync does not collide.

CI

Both ci.yml and cdn-deploy.yml now set FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true to suppress the Node.js 20 deprecation warning and opt in early before the June 2 enforcement date.

v3.4.4 (2026-04-10)

Admin Settings Restructure

Admin settings split into 7 focused pages under a SOLA category (Site admin: Plugins: Local plugins: SOLA). Replaces the previous single scrolling page plus experimental JS tab hack.
- General: enabled toggle, version banner, remote config URL
- AI Provider & Models: provider, API key, model, temperature, system prompt, max tokens, history, starter editor link, token analytics link
- Content & RAG: RAG toggle, embedding provider settings, chunk and top-k tuning, RAG admin link, performance content caps
- Safety & Moderation: quiz hide, off-topic detection, wellbeing, integrity checks
- Engagement: study plans, email and WhatsApp reminders, voice mode and realtime settings, surveys, usability testing, practice scoring rubrics
- Branding & UI: institution name, display name, welcome message, chat greeting, display mode, position, avatar and colors
- Integrations & Delivery: FAQ and Zendesk, Redash export, CDN delivery, plugin self-update
All 7 editor pages (Starter Editor, Survey Editor, Usability Testing Editor, Rubric Editor, RAG Index, Plugin Updates, Integrity Checks) now live under the same SOLA category in the admin tree.
Direct links to legacy /admin/settings.php?section=local_ai_course_assistant 404. Admins should use the SOLA category or any of the new local_ai_course_assistant_* section names.
All 92 existing setting fields and their saved values are preserved. No DB migration.

Bug Fixes

Fatal curl class not found on update_admin.php and rag_admin.php reindex path. \curl is not auto-loaded by Moodle. Added require_once($CFG->libdir . '/filelib.php') inside every class method that creates a \curl instance (plugin_updater, reminder_manager, zendesk_client, embedding_provider\base_embedding_provider, provider\base_provider). Previously these silently failed on cold includes.
Removed the obsolete JS tab navigation hack and duplicated top save button script from the single settings page, now redundant with the native multi page layout.

QA

Smoke tested all 9 admin pages (7 settings pages and analytics, token analytics, rubric editor, survey editor, usability testing editor, RAG admin, update admin, integrity admin, starter settings) via authenticated HTTP: all return 200 with zero errors and zero warnings.
Verified every analytics method, every manager class (survey, usertesting, rubric, token cost) runs without argument or signature errors.

v3.4.3 (2026-04-10)

Internationalization Cleanup

Replaced 17 hardcoded English strings in the widget template with Moodle string lookups: language suggestion banner aria labels, debug panel buttons (Refresh, Copy all, Close), voice panel title, Notes tab saved subtitle and empty state, history Saved and History tabs, LLM provider and model picker labels, and footer Usability Testing and Feedback links.
Added 17 new chat:* string keys to the English language file and translated all of them into the other 45 supported languages.
Backfilled chat:starter_help_page, chat:starter_ask_anything, and chat:starter_review_practice in 41 language files that previously fell back to English.
Approximately 925 new or backfilled translation strings across the full 46 language set.

Starter Translation Fix

Fixed a bug where conversation starter buttons did not re-translate when the student picked a different language at runtime. The client side gate was checking data-translatable, which the server template never emitted. Switched the gate to data-builtin, which the template already emits correctly. Also added data-builtin="1" to the fallback starter buttons rendered when starter_manager returns no data.

Voice Feature Click Fix

Fixed Conversation Practice and Pronunciation Practice clicks appearing to do nothing on non secure contexts (plain HTTP served over a LAN IP). The preconditions check ran after the UI already switched to voice mode, and the error message was routed through the chat message area which is hidden in voice mode. Reordered the checks to run before the mode switch and routed errors through the visible notification toast.
