FRC 2015 Software Updates

On the WPI Speedstep web site it shows that there’s been two updates to WPILib.

There’s no documenation on how to get these updates.
I tried updating via eclipse, but eclipse says that there are no updates available.

This link, where the WPI plugin was first installed, gives me a 403 error:
http://first.wpi.edu/FRC/roborio/release/eclipse/

Has anyone else been successful installing updates?
Thanks.

It must have been a temporary error.
I successfully updated the eclipse plugins via the eclipse ‘check for updates’.
