 🛠️ Bug fixes:
 
+* Fixed [Issue #173](https://github.com/DataLab-Platform/DataLab/issues/173) - Phase spectrum: add unit (degree) and function reference (`numpy.angle`) to the documentation
 * Fixed [Issue #177](https://github.com/DataLab-Platform/DataLab/issues/177) - "Open from directory" feature: unexpected group name (a group named "." is created instead of the root folder name)
 * Fixed [Issue #169](https://github.com/DataLab-Platform/DataLab/issues/169) - Signal / Fourier analysis: magnitude spectrum feature does not work as expected with logarithmic scale enabled
 * Fixed [Issue #168](https://github.com/DataLab-Platform/DataLab/issues/168) - Average profile visualization: empty profile is displayed when the target rectangular area is outside the image area (this has been fixed upstream, in PlotPy v2.7.4, and so requires the latest version of PlotPy)
