JSFiddle Console. Turn on/off in Editor settings.
☁️ "Running fiddle"

New Automatically expiring fiddles

Add expiration date to your fiddle (time button next to Save), it can be: 1 day, 10 days, 1 month, 6 months, 1 year, and you can keep the fiddle forever. Right now the default is Keep forever but this will probably change.
Ability to download a fiddle

We've added the ability to download a specific fiddle version from the Editor's interface. I'll be downloaded as a Zipped single HTML file.
Your recent fiddles when logged out

Saving a fiddle, even when you're logged out, will put it under the Your recent fiddles modal in the sidebar. They will eventually disappear (since they're anonymous), but now you'll have time to save them under your user after logging in.
Tailwind CSS

Added Tailwind CSS to the list of precompilers - even though it's really HTML, you can activate it from the dropdown in the CSS panel. Tailwind CSS would be best used with HTML Hot-reload enabled.
Code linting and formatting

We've replaced the dated code linter and formatted with more modern ones: Stylelint and Prettier.
JSFiddle 3.0
The 3.0 updates brings a lot of changes, most notably a modern UI refresh.

There was an increadible amount of under-the-hood changes for the front-end, we've mostly moved away from pre-processors. The light/dark themes are using a modern light-dark() approach. The refactoring allows for more changes to be made in a spedier manner.
- In the new sidebar you can find our mini-apps (right now the Color Palette Generator)
- System theme follows your OS settings
- CSS Hot-reload - styles update immidietly as you type
- HTML Hot-reload (experimental) - update HTML immidietly as you type
- Results panel color follows the selected theme
- Title and description are now a single field
- Public Profile page is completelty redesigned and can be easily used as your code showcase
- Groups are now Collections and we have big plans for them
- Collections are completely redesigned
- Users can now add groups straight from the editor
Import fiddles as modules

Import fiddle code into other fiddles with Modules and Imports.

JS Modules: import [name] from '@jsfiddle/[username]/[fiddle].js'

CSS Import: @import url('@jsfiddle/[username]/[fiddle].css')

See how this works in this fiddle.
Fiddle listing shows latest version

The fiddle listings (Public, Private, Titled, etc) will now display latest versions instead of the ones saved as Base versions - this was causing more confusion than good, so we decided to change this long-standing behavior.
Evaluate code into the console

Custom Console beta is getting more stable and feature-rich. Just added the ability to evaluate code in the console.
