PICUP Trinkets has had a lot of work done since it launched. Here are the changes you're most likely to notice.

Writing and running code

• Python is real Python. Your code runs actual CPython in the browser, so libraries like numpy and matplotlib work the way they do on a desktop — and there's now a single Python option instead of several confusing variants.
• input() works. Programs that ask the user for input used to fail immediately. They don't any more.
• Variables tab. See every variable your program creates, and click to expand lists, dictionaries and objects.
• Step through your code. Run your program, then walk through it one line at a time — forwards and backwards. Watch variables change, drag the slider to jump around, and click in the left margin to set a breakpoint and skip straight to the interesting part.
• Better plots and graphics. matplotlib labels no longer get cut off, and the VPython canvas can be resized properly.
• iPad friendly. The dividers between your code and the output can be dragged with a finger.

For instructors

• Publishing works. The Publish dialog previously did nothing at all when clicked. You can now publish a trinket to its own page and share the link.
• A My Courses page, and course deletion you can actually find.
• Manage trinkets in bulk — select several at once to move or delete them, with filters and date ranges to find what you need.
• Download student work, including your feedback, as a single export.
• Easier rosters. Students who already have accounts are enrolled when they log in, and adding a large class at once works reliably.
• Course pages behave. Image uploads work, the markdown editor highlights properly, and large course archives import without hitting a size limit.

Coming from trinket.io

• Old trinket.io links point at the matching trinket here.
• Imported course pages now show this site's trinkets, instead of quietly loading trinket.io's editor.
• Imported Python trinkets open correctly, including older ones that used to show "this trinket type is not available".

Fixes you'll simply stop noticing

• A whole classroom logging in from one network no longer gets locked out.
• Returning users aren't greeted with "your account has been created" every time.
• Renaming a course or trinket no longer breaks its old link.
• "Download All" only includes the trinkets you actually still have.
• Saving a course page no longer gets stuck on a "modified in another window" error.
