Version 2.0 of Graphs is a major update, introducing several new features such as proper equation support and a completely redesigned style editor.

Different data types:

Graphs now differentiates between imported data from files, generated data and equations
Equations now span an infinite range
Equations can now be edited afterwards, as well as simplified using the item editor
Equations with undefined values (e.g. 1/x at x=0) are now properly rendered as well
Operations on equations are now performed analytically, meaning the name of the equation will also change accordingly when performing operations
Generated data can now be changed afterwards with regard to step size and rendered span

New Style Editor:

Graphs has a completely redesigned style editor with a live preview of the edited styles
Styles can now be exported
New styles can now be imported from matplotlib-style files
Added the ability to draw tick labels (values) on all axes
The style editor now contains options to style the error bars

Reworked Curve fitting:

The confidence band in the curve fitting dialog is now correctly calculated using the delta-method
The curve fitting dialog now has the option to show residuals
The parameter values themselves in the curve fitting dialog are no longer rounded (e.g. 421302 used to be rounded to 421000)
The results in the curve fitting dialog now also show the root mean squared error as a second goodness-of-fit figure
The curve fitting dialog now shows more useful error messages when things go wrong
Custom equations in the curve fitting dialog now have an apply button, greatly improving the smoothness when entering new equations

Improved data import:

Revamped the import dialog, where the import settings can now be set independently for multiple files
Added support for sqlite database files
Added support for spreadsheets files (both .xlsx and .ods)
Added proper support for single-column imports, x-data can be generated using your own equation
Multiple items can now easily be imported from the same file at once
Imported data now supports error bars, with styling configurable per item or globally via the style editor

Quality of life changes:

It is now possible to have multiple instances of Graphs open at the same time
Data can now be imported by drag-and-drop into Graphs
The subtitle now also shows the full file path for Flatpaks
Limits can now easily be clicking on the numbers near the axes
The custom transformation has gained the following extra variables: x_mean, y_mean, x_median, y_median, x_std, y_std and counts
Settings that affect the canvas (item or figure settings) are now displayed in the sidebar, so you can immediately see the changes on your graph
Graphs now properly supports mobile screen sizes
Legend labels are now truncated dynamically to the window width, instead of to the previously fixed 40 character limit
Graphs now inhibits the session when unsaved data is still open
The resolution (image size) for exported figures can now be set manually
Added support for base-2 logarithmic scaling
Warnings are now displayed when trying to open a project from a beta version
Translation updates

Bug fixes and tweaks:

Graphical fixes for the drag-drop animations
Limit entries can now be properly set even for many significant digits
Panning and zooming are now done consistently on all axes when using multiple axes
Fixed a bug where the text size was set incorrectly after exporting a figure
Implemented a custom math parser, which is more performant and robust
Overall tweaks and refactors under the hood
