Users management mysql 5.6

Since Heidi v12.12 i have a problem with users management. I'm adding access to a table for a user, as shown in the image. Then I save and get the following error. As far as I understand, the syntax is incorrect and doesn't match my MySQL version (5.6). Please, help.

Error:

ALTER USER 'sokolov'@'%' REQUIRE NONE; / Ошибка SQL (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'REQUIRE NONE' at line 1 /

Yes such old MySQL versions were using different SQL statements for granting privileges. HeidiSQL does no longer support that old syntax.

MySQL 5.6 is from 2013, you should probably upgrade your server anyway.

Ideally, yes, but it's not always that easy... still, I guess the answer (short of upgrading MySQL) is to run SQL commands directly in a query window.
