Linked issues dropdown items difference

[Mariano Edvardsson]

Hello! Can anyone explain some of the different between 'mentions', 'is mentioned by' and 'relates to'?

Also I'm not sure what are the 'clones' and 'is cloned by' option in contrast to 'duplicates' and 'is duplicated by'.

If anyone can point me to documentation that explains each of these. 

Also, anyone deleted such options and shortened down the list for convenience?

Hello @Mariano Edvardsson 

Cloned/is cloned by is the link relationship assigned between two issue when you use the native Clone Issue function. If you are in issue A-1 and you execute the Clone Issue action to create issue A-2 as a copy of A-1, then

A-1 is cloned by A-2

A-2 clones A-1

This relationship is often used when there is a need to track similar work in different teams or different products or different versions of a product 

"Relates to" is a generic indication of a relationship between linked issues 

Duplicates/is duplicated by is usually used to indicate one issue is a duplicate of another where the duplicate does not need to be worked on and tracked separately from the original.

Jira Administrators can modify the list of link types that are available. Mentions/is mentioned by is not a link type that is set up by default by Jira, so that one was added by your Jira Administrators. You would need to ask them about when it should be used.
