 ### Fixed
-- Fixed a bug preventing backward compatibility when loading detectors (containing TensorFlow models) saved with `<v0.10.0`
-([#729](https://github.com/SeldonIO/alibi-detect/pull/729)). This bug also meant that detectors (containing TensorFlow models) saved with 
-`save_detector(..., legacy=True)` in `>=v0.10.0` did not properly obey the legacy file format. The `config.toml` file format used by 
-default in `>=v0.10.0` is not affected.
