We just released the latest build of Windows Live Toolbar. There are no new features in this release, it's fucosed mostly on stability and performance improvements. If you use the toolbar, I'd suggest you upgrade. And if you're not using WLT, well, be a chap and give it a test drive, would you? :-)
You can grab the bits from the WLT web page. After the install, you should be running version 03.01.0000.0130. You can check your toolbar version on the General page of the Settings dialog.
