JIRA VersionSearcher class

[gil]

I have a JIRA custom field addon extending the VersionSearcher class, but look like this class is removed in JIRA 7, based on this documentation: https://developer.atlassian.com/server/jira/platform/jira-7-0-api-changes/

Does that mean I must create my own class to do the version search as this VersionSearcher class is taken away in JIRA 7?
