# DeepFileX v2.0.0 - Major Upgrade (Explorer Dark UI, High-Speed CAD Indexer & Localization)
We are thrilled to announce the official release of **DeepFileX v2.0.0**. This major update introduces a complete visual overhaul, native high-speed CAD drawing indexing, advanced text cleanups, and full English localization.
## 🚀 Key Highlights & New Features
### 📐 1. Native CAD Drawing & 3D Model Indexing
* DeepFileX now parses and indexes the full-text content of CAD formats and standard 3D models.
* **Supported Extensions**: `.dwg`, `.dxf`, `.dwt`, `.step`, `.stp`, `.iges`, `.igs`
* Native support for AutoCAD layouts, block attributes, and embedded text fields.
### ⚡ 2. 20x~28x Hyper-Optimized CAD Parsing Pipeline
* **Bypassed Recovery Bottlenecks**: Implemented a hybrid parsing engine that bypasses the time-consuming 70-second heap-recovery scans for newer AutoCAD formats (AC1027, AC1032 / AutoCAD 2013-2018+).
* **Speed Improvements**: Scan times for complex DWG files have been slashed from 80 seconds down to **under 4 seconds** (up to 28x faster folder scans verified).
* **MTEXT Cleanups**: Embedded AutoCAD formatting codes (e.g., `\A1;`, `\fGulim|b0;`, `\P`) are automatically stripped, leaving clean, searchable plaintext.
* **Hangul CP949 High-Performance Filtering**: Integrated binary-byte checks for legacy and corrupted CAD fallback decoders to prevent garbage word noise.
### 🎨 3. Explorer-Style Dark Theme UI/UX
* Completely redesigned user interface with a modern, high-performance dark theme layout.
* Added a persistent indexing list panel, live operation progress trackers, and real-time scanning time estimations.
### 🌐 4. Full English Localization
* All user-facing UI elements, settings dialogs, update checkers, error popups, and console notifications have been fully localized to English for global usability.
