jCustomer 2.6.2 is a patch release containing a fix in a migration script to handle actions containing setPropertyValueMultiple.

This bug would have prevented affected environments for migrating from jCustomer 1x to jCustomer 2x. If you are already running jCustomer 2x, there is no added value in upgrading to jCustomer 2.6.2 (other than benefiting from changes present in earlier versions).

This version of jCustomer is based upon Apache Unomi 2.6.1.

The issue only impacted environments migrated to these versions from jCustomer 1x. Environments created on jCustomer 2.5.0 and 2.6.0 were not affected by this issue.
