New version fixes a regression appeared in 1.7.13 which causes unexpected duplicate entries in the JobParameters table when using SQL Server as a job storage with older schemas (V5 and below). This problem is caused by a changed query in the previous version, and that change is rolled back now. No other manual steps required to fix the issue.
