What is changing?

Related to: https://thepluginpeople.atlassian.net/wiki/spaces/JEMHC/pages/72908873/Understand+how+Issue+association+works#Email-threading. The previous Email Threading option found in your Profile > Project Mapping > Pre-Processing > Email Threading and Profile > Project Mapping > Rule > Pre-Processing will be removed as this option is not necessary on its own.

Both In-Reply-To and References when enabled will drive Original Issue Key and Message ID association based on the header related to the enabled check boxes.

Behavior Changes

1. If both In-Reply-To and References header options are enabled then In-Reply-To option will take precedence.

2. Message ID Embedded Issue Key will now take precedence over Original Issue Key and Message ID association

3. If both options are disabled then previously we would depend on the main checkbox Email Threadingcheckbox however this property has been removed. Now the options: Use References Header checkbox and Use In-Reply-To Header checkbox will drive Email Threading.

Am I affected?

If you have previously only enabled the Email Threading and none of the sub options Use References Header checkbox and Use In-Reply-To Header checkbox then you may be affected.

What do I need to do?

Due to the removal of the Email Threading option and used this to drive email threading you will need to enable the appropriate header option.

If you wish to achieve the same as previous behaviour then enabled both the Use References Header checkbox and Use In-Reply-To Header checkbox.
