Note: If you find missing information about particular minor version, that version must have been changed without any functional change in this library.

Note: Due to some last quick changes on v4, detail of v4.5.3 & v4.5.4 are not updated here. v4.5.4x is the last tag of v4 in github repository. I'm extremely sorry for the confusion
