Please note: unlike 1.4 in 1.8 you will replace 3 things: the entire images directory, kepub directory, and database.
JCKobo posted this elsewhere, but it should probably go here, as well:
We have a brand new, clean database for those of you who have upgraded to 1.8 and either a) are having problems post upgrade, or b) want dictionary functionality in the pre-loaded books (as this will upgrade your books to our new format, which the firmware update will not)
The steps for installing this update (as well as the caveats) are the same as in the sticky posted in this forum, except that the download link is different.

For those of you who are more Linux savvy, or want to follow timlegge's instructions on creating SD cards, we have a link to the SD card image for this software as well.
You can download this from here:
This will literally reformat your device, so make sure you have anything you want off the device first.
I hope this helps with your 1.8 experience.
