We have uploaded the new update to all worlds and after maintenance tommorow it will be live. You do not have to do anything but when you login you will see a "Resource Update" window which is the client attempting to download the new update. It will run of it's own accord and when you arrive inworld you'll be ready to go.
If you experience any problems with this we will be standing by ready to help, send an e-mail to firstname.lastname@example.org and we will endeavour to get back to you as soon as possible. The last time an update was performed like this was around 1999/2000 so we are going to be monitoring things closely to ensure they go smoothly.
Alternatively you can check out this topic we previously posted which links to an installer if you are having trouble with the auto updater. [Read More]
