Paypal Commerce (Extension ID: paypal_commerce)

[Heemet]

I have AbanteCart v. 1.4.3 installed.  I have been using Paypal Express Checkout (Extension ID: default_pp_express) and see that it is not confirmed to work with AbanteCart v. 1.4.3.  I'd like to switch to Paypal Commerce (Extension ID: paypal_commerce), but there is a message in my admin portal that "New version (1.4.4) is available. Click to update now."  The link to update does not work. 

Where can I find v. 1.4.4 of Paypal Commerce?

Thank you!
