medcat/v2.0.0

We’re excited to announce the release of MedCAT v2. This is a major refactor that brings a more modular, flexible, and maintainable foundation for clinical NLP, while staying compatible with existing v1 models.

This release focuses on:

Refactored structure for lower coupling and greater extensibility
Modularity via optional install extras (install only what you need)
Improved flexibility in tokenization, NER, and annotation pipelines
Backwards compatibility for v1 models, with automatic conversion

✨ What’s New

Decoupled from spacy → now possible to use lightweight regex tokenizer or other (custom) backends
Optional extras: install support only for the components you need (spacy, meta-cat, deid, rel-cat, dict-ner)
Training is now structured around dedicated classes for clearer workflows
Tutorials and scripts have been rebuilt from the ground up for v2
Added support for a supervised training web service (experimental, under development)

⚠️ Breaking Changes

Saving/Loading:
- Save method has a new name (CAT.save_model_pack)
- v2 saves models in a new format (but still loads v1 models, with slower load times due to conversion)
Training:
- Training APIs now go through separate trainer classes
Defaults:
- Default install no longer includes spacy or advanced components (see migration guide for how to enable them)

For a complete list, see: BREAKING_CHANGES.md
