New

Skins (free): a background picture behind Canvas, from your own computer or from a shared .bsctheme file. Up to four, with a separate picture for light and dark mode if you want one. A wash of your theme's color keeps text readable over any picture — measured against the picture itself, so it is only as strong as it needs to be.
Weighted GPA you control (Pro): a weighted/unweighted switch, editable points per course type (AP, IB, concurrent enrollment, dual enrollment, honors), and a table to tag each course.
Sports-eligibility early warning (Pro): the rules your school uses, each one a switch with a number, and a meter that warns before the line. An early warning, not a decision.
Canvas's new card dashboard is fully supported: card colors, pictures, hiding and reordering.
A built-in tour, opened on first install.

Fixed

What's Due and reminders now use a student's own due date when a teacher has set a different one in Canvas. They previously used the class date, which could show work as overdue before it was due.
"Hide submitted" asks Canvas what has been turned in, instead of guessing from the page, and now actually hides it.
The page no longer jumps between the GPA panel and the list in List View.
The settings page follows a dark-mode schedule, rather than always previewing the light theme.

GPA ring — radial meter against the scale max, letter grade printed beside it, dashboard.gpaRing on by default, falls back to the plain hero figure when off

Blur grades fixed — the tag is applied unconditionally and the stylesheet decides, so it now works on the dashboard and cards, not just the course grades page; the ring arc and bars go invisible rather than blurred, since a bar's length reads straight through a blur

New-dashboard notice — a dismissible bar when Canvas's redesigned dashboard is detected, pointing at the classic-view switch

Diagnostics dashboardShape() — report version 4, plus the "Copy dashboard structure" button that only appears when there's actually an undecoratable dashboard

Popup tile grid — eight deep-link tiles over the quick toggles, with jumpToHash() on the options page
Settings control restyle — switch, segmented group, slider, select and checkbox on one rhythm
