Full Changelog: v0.19.0...v0.20.0

v0.18.x: Improved plotter accuracy

In #135, the adaptive plotter was improved to more accurately plot highly periodic functions, and also to avoid plotting duplicate points. This should give a quality boost to most plots, but may slightly alter some. The sampling depth parameters are now "one lower", meaning that if you were previously passing maxSamplingDepth={15}, for example, you should now pass maxSamplingDepth={16}. Change is annoying, but the depth made no sense before, and now it does (a depth of 16 means 2¹⁶ subdivisions).

In this janky screenshot of a visual regression test, you can see the improved density of sin(1/x).

v0.17.x: Experimental LaTeX support

Mafs now supports basic LaTeX (which really just means embedding KaTeX in the Mafs view. This component is experimental, and doesn't work very well in Safari (it's not completely broken, but there are some visual bugs when scrolling).

See the docs →

v0.16.x: Polylines and Inequalities

Mafs now supports plotting inequalities with Plot.Inequality, and also drawing Polylines (rather than just closed polygons).

v0.15.x: Zooming!

Mafs now supports zooming on desktop and mobile using the mouse wheel, trackpad, and keyboard (- and +)! Check out the Mafs docs for details on how to use it.

v0.14.x: Polar coordinates!

Mafs now supports polar coordinates.

• CartesianCoordinates is now Coordinates.Cartesian.
• Polar coordinates can be displayed via Coordinates.Polar.

See the docs on coordinates!

v0.13.x: `vec` matrix operations performance improvements

• This is a small but mighty release, in which vec's representation of a Matrix got changed to 2x3 matrix to save some time and memory. Some functions in vec were also rewritten to reduce function calls. Thanks @sritchie for this change (#92)!
• Mafs now has visual testing for all examples on the docs site. This greatly increases the confidence in shipping changes to Mafs.

v0.12.x: Fixed TypeScript types

Mafs now uses TypeScript itself (rather than Parcel) to generate TypeScript definitions, meaning the types exported by Mafs will be much more accurate (see issue #90). This is shipping as a minor version update because there may be minor backwards incompatibilities (but only with types).

v0.11.x: Custom components!

• v0.11.1 and v0.11.2 address bugs relating to the --mafs-user-transform custom property being blank when there are no Transform components on the canvas.

Mafs now supports custom components! Send in the dancing pizzas:

This release exposes a few APIs for end-user consumption:

• --mafs-view-transform and --mafs-user-transform, which are CSS matrices for use in style.transform attributes.
• useTransformContext, which are those same matrices but accessible from JavaScript.
• vec.toCSS(matrix) which will print a matrix ("matrix(...)") for usage in CSS/SVG.
• usePaneContext which indicates which "panes" are visible to the user, allowing you to avoid rendering offscreen elements.
