Release notes
Comments:
Drupal8 branch will no longer depend on external calendar module.
Calendar pop up functionality is part of drupal8. Works with Chrome only at the moment.
Known issues.
Malformed local task tabs ( admin/config/services/simplereservation/items )
see https://drupal.org/node/2165085
The action/trigger mechanism that exist in the drupal7 version don't work ... yet.
Drupal core is in a state of flux ... and these will be added hopefully before a core release candidates appears.
Next Steps
AJAX support for next week, previous week buttons on /simplereservation page
At least SOME unit functional or integration testing.
