This update introduces critical security enhancements, major performance optimizations for document management, and full compatibility with the latest reasoning models. Performance & UI Optimizations: - Instant Document Deletion: Upgraded vector deletion logic to use batching. Removing documents from your index is now up to 10x faster. - Optimistic UI Updates: Deletion of indexes and namespaces now updates instantly in the UI for a much snappier experience. - Namespace Management: Added a new Namespace deletion option directly in the Documents tab so you can wipe custom namespaces cleanly. - Background Syncing: Index lists now sync seamlessly in the background across views. Security & Architecture: - Secure API Key Storage: API keys are now stored exclusively in the system Keychain via a secure settings store, replacing process environment variables. - UserDefaults Hardening: Wiped legacy plain-text API credentials from unencrypted UserDefaults storage. - Reasoning Model Support: Updated API parameters to fully align with latest OpenAI models, including native reasoning effort configuration and completion token limits. Stability & Bug Fixes: - Migrated navigation toolbars to cross-platform SwiftUI layouts to improve UI stability. - Resolved background streaming task retention warnings. - Expanded unit test coverage across all core services for improved reliability.

Version 2.2 brings GPT-5.2 support, smart prompts, and bunch of other stuff. I reworked the UI entirely.. GPT-5.2 REASONING MODEL • Full GPT-5.2 support with 400K context and 128K output tokens • New reasoning effort levels: Off, Low, Med, High, and Max (xhigh) • Updated token limits for modern AI capabilities SMART EXAMPLE PROMPTS • Contextual prompts based on your selected index and namespace • Four categories: Discover, Analyze, Extract, Compare • Tap any suggestion to instantly search • Prompts adapt when Charts & Calculations is enabled CHARTS & CALCULATIONS (Code Interpreter) • Visualize data from your documents as charts • Calculate totals, averages, and trends • Extract structured tables and export to CSV/JSON • Create timelines and comparison visualizations • Quick Settings panel with sliders and presets • Haptic feedback and custom system prompts

Version 2.0 brings foundational improvements to answer generation, reliability, and user control. OPENAI RESPONSES API & GPT-5 • Migrated from Chat Completions to structured Responses API • Native GPT-5 reasoning model with dynamic effort controls • Existing models (GPT-4o, GPT-4o mini) continue with temperature/top-p • Settings UI conditionally renders correct parameters • Structured "input" field with system/user content arrays SERVER-SENT EVENTS STREAMING • Answers stream token-by-token instead of blocking • Typing indicator appears immediately while waiting • Stop button cancels mid-generation with clear feedback • Watchdog timer detects stalls and triggers fallback completion CONVERSATION MEMORY • Bounded client mode includes last ~8 messages for context • Server-managed threads use OpenAI conversation IDs • Toggle between modes in Settings for privacy preferences • Follow-ups understand prior exchanges without restating RESILIENCE & CIRCUIT BREAKER • Pinecone health checks run before queries with short timeout • Circuit breaker prevents calls to unhealthy hosts • Per-search trace IDs tie logs to specific queries • Error banners auto-dismiss with user-friendly summaries PRIVACY & RESET FLOWS • Settings > Data & Privacy exposes credential reset • Clears Keychain, conversation history, bookmark consent • Onboarding messaging clarifies missing keys • Preflight script blocks accidental credential leaks CITATION STABILITY & POLISH • Citations enumerate by offset—no duplicate ID warnings • Logs tab filters with color-coded levels • Index host transitions emit structured logs • Improved keyboard handling and haptic feedback Behind the scenes: upgraded to OpenAI Responses API, added conditional model parameterization, implemented SSE parsing with cancellation, and wired bounded conversation memory. All changes maintain backward compatibility with existing documents and Pinecone indexes.
