Development release for Adpativetheme Drupal 8.
The D8 version of Adaptivetheme is a total re-write of the core theme and sub-themes. The admin theme has been removed also.
You MUST enable AT Core
This theme uses OO PHP and autoloads classes - this does not work in Drupal 8 when the base theme is not enabled - if you try to enable a sub-theme without first enabling AT Core you will get fatal errors on both the sub-themes Appearance settings page and in the front end.
Everything is treated as a Block
NOTE: this current version anticipates the commit to Drupal 8 of the "convert everything to a block" patches. This means that if you enable this theme you will not see things link the Logo, Site name or slogan, Page titles, Tabs, Actions links etc etc. The one page level variable I have included as a legacy support feature is the Messages variable, because we really need that during development. When the D8 patches are finally committed this will be removed.
I have created a small sandbox module that implements these blocks - you can use this if you prefer not to apply core patches, note I will try to keep the module up to date:
