Can I keep existing theme customisations from version 1.5?
No. Pixaria 2.0 has so many changes that it is not possible to use a custom theme or customised templates from version 1.x. When you upgrade, your default theme will be set to ‘Illuminux’ the new default theme that ships with Pixaria 2.0. Once you’ve upgraded, you can then make a copy of the ‘Illuminux’ theme if you want to apply previous customisations.
