Provides several new custom fields for Jira and number of available custom fields are increasing. You can request new type of custom fields in our issue tracker if you want.

For the replacement fields you can easily migrate by changing a database record easily and without any data lost. Please don't forget to backup just in case. Most functionality of the custom fields can also be updated by REST API so that you can integrate them to your own customizations. For the complete description of each custom field please refer to the user manual.
