Last Commit (fix for null field inserts) not done in master?

Regarding the recent commit https://github.com/walkor/mysql/commit/28272aa68f9ea1a482f9bb0cf709d169f772d228
Could you commit the last fix to master branch too ? also for my own curiosity, why put it there and not master?

Thanks again for the great libraries and code

Review commit 28272aa68f9ea1a482f9bb0cf709d169f772d228 and compare its changes with the master branch. Check the null-field insert fix in the MySQL connection library, then verify that the same fix is present and working on master.
