Release notes

Adds a service worker to CalcMe. This allows CalcMe to be loaded and work without internet connection after the first visit, except for the evaluation calls. This also completes the integration of CalcMe as a Progressive Web App, so users will be able to easily install CalcMe as a “standalone” mobile or desktop application.

Adds the empty set symbol to the accordion bar.

Adds the new units supported by Wiris CAS to the accordion bar.

New “File” menu.

Fill and fill_color commands now work properly.

Arc command now works properly.

Buttons that insert functions now use the selected list item separator instead of the default one.

Fixed some bugs that occurred after changing the language of the session.

“write” command now works properly again with random arguments regarding label placement.

Usage of “label” argument in the plot function does no longer make plotters crash.
