• English & Persian — UI language + automatic message text direction
• Onboarding — Short first-run tour (language, tips)
• Multi-provider — OpenAI-compatible profiles + Ollama out of the box
• Agent tools — Web search, knowledge base search, image analysis, audio analysis, image generation (gpt-image-1 / DALL·E / Flux)
• Local RAG — Chunking, embeddings (Ollama or API), citations in assistant replies
• Power user — Branching, fork, templates, bookmarks, command palette, usage analytics
• Polish — Skeleton loaders, j/k navigation, cost estimates, desktop notifications, update check

What's new since v2.2.0

Models & providers

• Header model selector with capability badges (Vision, Image Gen, Tools, Reasoning, Embedding, Audio)
• Multiple provider profiles — switch OpenAI-compatible APIs and local Ollama
• Per-conversation last_model memory; advanced flyout (temperature, max tokens, system override)
• Token usage footer with context bar and estimated cost (editable price table in Settings → Storage)
• Slash commands — /new, /clear, /model, /export, /temp, /help, /prompt

Knowledge & library

• Library page — browse all attachments with filters (images / files)
• Local knowledge base (feature-flagged) — folder indexing, chunking, embeddings, top-k retrieval
• Citation markers [1] in markdown with clickable source links
• Improved PDF and DOCX text extraction

Agent & multimodal

• web_search tool (DuckDuckGo) when enabled in settings
• search_knowledge_base tool when knowledge base is on
• generate_image tool — LLM requests image creation like ChatGPT; uses configured image-gen model
• Vision (analyze attached images) separate from Image Gen (create images)
• Tool call inspector — expandable JSON per tool round

Conversation management

• Ctrl+K search modal with grouped results (Today, Yesterday, …)
• Pin, archive, rename, ChatGPT-style context menu, folders/projects
• Settings → Advanced — RAG, tools, usage in collapsible sections
• Ephemeral (temporary) chat — nothing written to disk
• Draggable sidebar resize (220–360px), collapse persisted

Productivity

• Message bookmarking and filter view
• Fork conversation from any message; inline branch picker on regenerate
• Conversation templates — save and start from presets
• Share as HTML export; copy entire thread as Markdown
• Command palette actions (> prefix in Ctrl+K)
• Raw API prompt viewer (dev mode)
• Local usage analytics (tokens over time)

UX & accessibility

• Empty chat state with logo and suggestion chips
• Smart scroll + “↓ New messages” chip during streaming
• Message edit, retry on failure, compact hover icon actions (copy, share, regenerate)
• LaTeX (KaTeX) and Mermaid diagrams in markdown
• Drag-and-drop / paste images; per-conversation draft persistence
• Skeleton loaders; j/k message navigation
• Styled confirm modals; header overflow menu
• prefers-reduced-motion; focus traps; aria-live streaming region
• Desktop notifications when generation completes
• Check for updates (GitHub releases API)
• First-run onboarding and Persian/English with auto RTL/LTR per message

Rebrand & packaging

• Product identity ThatGPT (com.thatgpt.desktop)
• Rust crate renamed to that-gpt — process shows as ThatGPT.exe / that-gpt.exe
• Legacy data migration from com.chatnest.desktop on first launch
• Theme key migration (chatnest-theme → thatgpt-theme)

---

Upgrade notes

1. First launch may copy data from %APPDATA%\com.chatnest.desktop\ if present.
2. Settings live at %APPDATA%\com.thatgpt.desktop\.env.
3. Enable optional features in Settings:
   • Web search
   • Local knowledge base + embedding model
   • Dev mode (raw prompt viewer)
   • Model prices for cost estimates
4. For image generation, set an image-gen model (e.g. gpt-image-1) in Providers and use a tools-capable chat model.
