I have Drupal 8 installed beginning of RC1 and afterward upgraded successfully up to 8.0. The status report page from the very first version is displaying:
Entity/field definitions Mismatch detected
Mismatched entity and/or field definitions.
Currently I have some common extensions installed but at the beginning the error was displayed even in the core.
My webpage is in polish language.
I was trying to install drush tu update entities but can't get it working properly (http://drupal.stackexchange.com/questions/179201/command-entity-updates-...).
