London Creative + comes with fully working contact form, awesome slider for your featured images, nasty spinning slider buttons (never saw them anywhere else, so you can call it unique), 2 message buttons under the slider and PrettyPhoto plugin (better clone of Lightbox).
Version 5.0 is not backwards compatible with previous versions. We have rewrote the whole codebase so it’s basically a brand new theme. Please do not attempt to update your older installations with v5.0+, it will not work. If you are already running an older version, there is no need to use v5.0 because it is mostly the same theme, we have just upgraded it to our new framework.
