[wp-hackers] Multi and single widgets

[Nicholas Ciske]

Yes, single widgets are legacy widgets (made before the Widgets API was available in 2.8, released in 2009).

If there are any left, I'm not sure you'd want to support them -- I'm sure they are marked as 'older than 2 years' in the plugin repo.

I am getting the idea that a "multi-widget" is just a widget in a modern WP install, and a "single" widget is a piece of historical detritus.
