## [v0.2.77] - 2024-08-04

Significant improvements in text processing and performance:

- 🚀 **Dependency reduction**: Removed dependency on spaCy model for text chunk labeling in cosine extraction strategy.
- 🤖 **Transformer upgrade**: Implemented text sequence classification using a transformer model for labeling text chunks.
- ⚡ **Performance enhancement**: Improved model loading speed due to removal of spaCy dependency.
- 🔧 **Future-proofing**: Laid groundwork for potential complete removal of spaCy dependency in future versions.

These changes address issue #68 and provide a foundation for faster, more efficient text processing in Crawl4AI.
