I cant understand why Opera decided that users from Ukraine should use YANDEX????
May be check statistics of usage???? Especially because Yandex is RUSSION resource, and searching in another way.
Of course i can change manually, but that is owfull to change it for all users where i am working. Most users in Ukraine will never use Yandex search (exception if they dont know how to change it).
Implement selection/configuration as it was in previous version, or change it please to GOOGLE in UA zone in next releases.
