+## Issue tracking (where file new issues?)
+
+At the time of writing, the Jenkins organisation let to the maintainer the choice of which issue tracker to use. Available are Github or [JIRA](https://issues.jenkins.io) issue tracker.
+For reason discussed in the Jenkins Developers Google Group the official issue tracking for this plugin is [JIRA](https://issues.jenkins.io/browse/JENKINS-74965?jql=project%20%3D%20JENKINS%20AND%20component%20%3D%20bitbucket-branch-source-plugin%20ORDER%20BY%20created%20DESC).
+
+What means:
+* new issues must be open at JIRA
+* the Github tracker will be froozen, that means no new issues will be accepted
+* depending on the progress I expect that by the date 01/06/2025 the Github issue tracker will be disabled at all
+
+What will happen to the issues opened in Github?
+* actual issues will be processed
+* maybe resolved
+* otherwise after 6 months, it will be manually migrated by me to JIRA if it doesn't already exist
+
 ## Notes
 
-* Unlike GitHub, in Bitbucket, [team admins do not have access to forks](https://bitbucket.org/site/master/issues/4828/team-admins-dont-have-read-access-to-forks).
+### General notes
+
+Unlike GitHub, in Bitbucket, [team admins do not have access to forks](https://bitbucket.org/site/master/issues/4828/team-admins-dont-have-read-access-to-forks).
 This means that when you have a private repository, or a private fork of a public repository, the team admin will not be able to see the PRs within the fork.

 Classes under the packages `com.cloudbees.jenkins.plugins.bitbucket.api` is intended to be public api and can be used to extend functionality in other plugins. Changes in the method signature will be marked with @deprecated providing an alternative new signature or class to use. After a reasonable time (about a year) the method could be removed at all. If some methods are not intended to be used then are marked with `@Restricted(NoExternalUse.class)`.
