This release enhances several aspects of the spey workflow:

* Users will be able to access the gradient and hessian functions of the statistical models.
* Enhance the logging structure of the package, including debugging tools.
* Gradient execution has been optimised for faster optimisation.
* Spey will be able to provide BibTeX information for third-party plug-ins through their arXiv number, DOI and Zenodo identifiers (if provided in plug-in metadata).

What's Changed
* Logging and BibTeX by jackaraz in https://github.com/SpeysideHEP/spey/pull/32
* Optimise gradient execution by jackaraz in https://github.com/SpeysideHEP/spey/pull/31
* logging, gradients, and BibTeX by jackaraz in https://github.com/SpeysideHEP/spey/pull/33

This release updates a typo in the computation of $\sigma_\mu$, which causes the function to crash. Additionally, text-based types are changed to literals to improve the interpretability of the code.

What's Changed
* Update documentation in https://github.com/SpeysideHEP/spey/pull/27
* Update typing in https://github.com/SpeysideHEP/spey/pull/30
* Bugfix in $\sigma_\mu$ computation in https://github.com/SpeysideHEP/spey/pull/29


**Full Changelog**: https://github.com/SpeysideHEP/spey/compare/v0.1.4...v0.1.5

This version includes a minor update for numeric comparison during the computation.

What's Changed
* Numeric instability due to comparison with zero in https://github.com/SpeysideHEP/spey/pull/25
* Update documentation in https://github.com/SpeysideHEP/spey/pull/26
