Git commits¶

while Contributing or doing git commit please specify the breaking change in your commit message whether its major,minor or patch

For Example

git commit -m "your commit message #major"

By specifying this , it will bump the version and if you dont specify this in your commit message then by default it will consider patch and will bump that accordingly
