This release allows the action to run in multiple jobs, by pulling before creating the new commit.
Please keep in mind that this will work only if the jobs are fired subsequently, it won't work if they are run at the same time: in that case, only the first commit will get pushed, while the other will get rejected by the remote.
To run jobs one after the other you can use the needs parameter: link
Important: this will only work if you're using actions/checkout@v2, using other major versions may not work.
