I am unable to update a Mage2.PRO extension

I ran composer update mage2pro/square and get update to 1.4.2 version.
How can i get the 2.0.0 version released?

Composer should notice new versions automatically.
I have spent my valuable working time now, and in my case Composer has correctly detected the latest extension’s version:

I had already version 1.4.2 after running the composer require mage2pro/square started updating and the stopped with installation failed message

How steps should i follow to get successfully installation?

Still not able to update the square extension.
Any suggestion?

I have updated your website myself with composer update (all packages).
BUT IT IS THE LAST TIME I DID IT FOR FREE.
Next time pay me or do not disturb me.
