This release implements two major changes to **PyAutoFit**:
**Results Output**
Result metadata was previously output as `.pickle` files, which were not human readable and depended on project imports, hurting backwards compatibility.
All metadata is now output as human readable `.json` files and dataset as .`fits` files, making it a lot more straight forward for a user to interpret how data is stored internally within **PyAutoFit**:
Here is an example of the `search.json` file:
All internal functionality (e.g. the sqlite database) has been updated to use these files.
All workspace documentation has been updated accordingly.
**Nautilus**
Recently, a new nested sampler, Nautilus (https://nautilus-sampler.readthedocs.io/en/stable/), was released, which uses machine-learning based techniques to improve sampling.
This release implements this.
