With versions prior to 0.2.3 and WordPress 2.1, problems arose with the links menu and category clouds. This was basically down to the deprecated category functions and back-end changes to the way categories work in WordPress 2.1.
Anyway, all is fixed, I’d like to go into it more, but it’s late and I’m off to bed.
Anyone using WordPress 2.1 or thinking about upgrading should definitely download this version. It’s backwards compatible with WordPress versions lower than 2.1, you just won’t see any difference.
Download Durable v0.2.3
Update: Durable v0.2.5 has been released to address some unforseen errors in the menu.
