    • For now, you don't have anyway to fund this project but maybe in future I update this.

    Supported versions

    We always recommend you to use the most latest version for more methods and better performance.

    If you are at v1.x.y and I launched a new version 2.0.0 do not update it. Because it is major change which may (basically always) break your present code or the output is not as expected.

    If you are at same major change version but a new patch/minor changed version is available install without any fear. Usually minor change comes with some new methods, and patch release comes with bug fixes/updated readme.


    Thanks goes to these wonderful people (emoji key):
