Version History

Fixed LOTS of bugs

• Should flow much easier now.

Universal File Converter

• HEIC → JPEG, RTF → TXT, plus pluggable strategy pattern for future types—just upload & go.

True Tab Multitasking

• Brand-new Tab enum drives the entire nav stack—jump between chats & vector stores instantly.

Instant Vector-Store Actions

• Optimistic deletes & uploads with real-time file counts; rollback safety net if the API balks.

Turbo-Loading & Empty States

• Dynamic progress messages, glassmorphism spinner, and a guided “no assistants yet?” screen.

Auto-Refresh Everywhere

• Observer & NotificationCenter overhaul keeps chats, assistants, and vector stores in sync—no pull-to-refresh required.

Background-Safe Fetch Queue

• New serial queue prevents race conditions when hammering the OpenAI API.

Codebase TLC

• Cleaner project file, tighter Combine pipelines, smaller debounce windows, and 800 net LOC of fresh Swift.

Reasoning-Effort Picker Fix

• Removed redundant “Default (medium)” option—caption now clarifies Medium is default.

Massive README Overhaul (devs: see GitHub)

— 15 commits • +1 200 / −460 LOC • 4 Features • 5 Improvements • 1 Fix
