1.0.1 (March 14th, 2023)
------------------------

Summary
~~~~~~~

- Released Mar 14th, 2023
- 9 contributors
- 31 pull requests since v1.0 (not all listed below)

This is the first bug-fix after v1.0. Several minor bugs and typos in the documentation are corrected.

- Few corrections have been made to improve the performance of the models evaluation in particular for 1d 
  spectral analyses.
- The "TIMESYS" keyword was not properly exported to the lightcurve table format. This is now corrected.
- An issue with interpolation in scipy 1.10 is causing problems in Gammapy. This specific version is
  excluded from dependencies. The minimal numpy version is now 1.21.
- Models created from files with a parameter scale different than one were incorrect and this will be fixed 
  by this patch. Note that by default gammapy always serializes the parameters with a scale of unity, so this bug 
  affected only files written by hand with a scale different from one.
- Datasets serialization now correctly supports PSF in reconstructed energies used in HAWC analyses.
