Payment providers source code are now available on GitHub
The source code for payment providers, including PayPal, DIBS, DataCash have been released to GitHub. These projects were upgraded to work with latest version of Commerce (11.2.2) and other components, that contains a few fixes and refactoring. They're now open-source and you might be great contributors :). We'll continue to update them. It means that we'll do continuous releases for them but they might be updated less frequently (than Commerce packages). It also means that we won't provide source code packages for those projects (.zip files) from the release 11.2.2. If you need the source codes, you can download from GitHub.
So now with the /nSoftware payment gateways, which has been available on GitHub from about 1 year, we have now 4 payment provider projects on GitHub. Please visit the repository on GitHub for more detail.
All documentation related to installation/configuration are still on EPi World.
