Trigger Jenkins build based on a new GitHub release or commit to the master branch

Question

I realize this question has been asked before here, here, and here, but none of these solutions appears to be working for my Jenkins setup and I can't figure out why.

My objective is to trigger a Jenkins build when either a new commit is made to the master branch or when any tag (or in GitHub, a release) is added to the repo. Here's my current setup:

When I make a new commit to the master branch, a new build is triggered. But when I add a new GitHub release, nothing happens.

Looking at my "Git Polling Log" shows the following output:

Done. Took 0.2 sec
No changes

Note that I'm using git polling once per minute. So it appears that git correctly detects the new branches, but somehow the git polling Jenkins is doing does not think a new branch qualifies as a "change" since it keeps reporting "No changes" at the bottom.

I have searched on this for sometime and was able to figure out the solution for triggering the jenkins job when tag is released from git hub. Here is the screenshot. Select advanced option from where git repositories are given and configure the details as below. So when release is tagged the jenkins job is triggered.

Refspec value should be +refs/tags/*:refs/remotes/tags/*.
