License Optimizer And Jira E-Mail Notifications

Starting with Jira 8.19.0, users who don't have a license assigned while they are inactive won't receive email notifications by default.

The previous behaviour was flagged as a security vulnerability in https://jira.atlassian.com/browse/JRASERVER-72737.

You can read more about it here: https://confluence.atlassian.com/jirakb/jira-notifications-batched-and-non-batched-not-sent-anymore-to-some-users-after-jira-upgrade-to-8-19-0+-1096091978.html

However, Atlassian decided to add a dark feature that allows you to change that again (read https://jira.atlassian.com/browse/JRASERVER-73165 for more details).
However, not all versions support that. For instance, Jira 8.21.x does not contain this feature.

Only the following versions support it:

• Any version 8.20.x from 8.20.6 (for example 8.20.6, 8.20.7, 8.20.8, etc...)

• Any version 8.22.x from 8.22.1  (for example 8.22.1, 8.22.2, etc...)

The dark feature flag is called

There is another update from Atlassian about this at https://jira.atlassian.com/browse/JRASERVER-72737 that states that at the same time, Jira 8.13.19+ will have the option to enable it with a regular feature flag. 

For Jira 9, we can confirm that the dark feature is still working and notifications are being sent properly.
