Add new parameter firstRelease for fitting occasion with no release.

I try to fix #20.

Finally, I successfully learned how to set a signature for my commit.

After completing my first simple project, I realized that the commit before the first release had many tests and confusing fixes.

Perhaps the commit from the beginning of the project to the completion of all basic functions is not suitable as the publishing of the first release. I should use the function introduction to complete the introduction of the first stable version.

I will close this request and complete my personal project in a better way.

Thanks for taking a look at it. Initial project work is tough. Your approach is similar to what I've done. Once my project was in a ready state, I cut an "initial release" to show that it was in a place to start. Then I was able to changenote all that came after.

Awesome work finding out that it didn't work though. Seriously its super helpful in OSS to know what doesn't work and what shouldn't be added. I appreciate it.
