## <a name="bugs"></a>Bugs resolved
### Core CiviCRM
-**[CRM-21445](https://issues.civicrm.org/jira/browse/CRM-20941) Ensure "Pay Later" processor is set so a fatal isn't thrown
Fixes an issue where string '0' wasn't being treated as false. So the checking of whether there is an empty value is now done in the on change listener for the full text search switcher
-**[CRM-21562](https://issues.civicrm.org/jira/browse/CRM-21562) Fix line item mis-saving when using a ',' as the thousand separator
Fixes an issue where the check to see if the MySQL server was a MariaDB instance wasn't working right. This lead to hard crashes as queries were being incorrectly re-written
