Upgrading never have been easier!
You can upgrade from any LEPTON 3series to LEPTON 4.0.0.
Usage: just download the LEPTON 4.0.0 stable package, unzip the file to your desktop and load the content of "upload" directory to your webspace via ftp. Call your domain in your browser, add ' /install' (something like http://www.yourdomain.tld/install/) and press enter.
You should get a message that you succeeded.
Keep in mind 1: if your installation originally was upgraded from a release lower 2.0.0. or from WebsiteBaker you have to modify the access-files within the page directory.
There is a thread on the forum that holds the information what to do.
Keep in mind 2: addons, that are not delivered with the package, had to be adapted to LEPTON 4 series, but this is not a big deal at all.

Note: don't forget to backup your files and database before uploading new release!
