 There are three relevant Jenkins jobs that should be used for a release flow:
 
-**a.** **Test runs:** **[iojs+any-pr+multi](https://jenkins-iojs.nodesource.com/job/iojs+any-pr+multi/)** is used for a final full-test run to ensure that the current *HEAD* is stable.

 ### 2. Produce a Nightly Build _(optional)_
 
-If there is a reason to produce a test release for the purpose of having others try out installers or specifics of builds, produce a nightly build using **[iojs+release](https://jenkins-iojs.nodesource.com/job/iojs+release/)** and wait for it to drop in <https://nodejs.org/download/nightly/>. Follow the directions and enter a proper length commit sha, a date string and select "nightly" for "disttype".
