v4.0.0

New features support:

• Partial Returns
• Collection Items
• Catalog Sync
• Effects in getCustomerSession
• Loyalty Transactions retrieval
• and more...

⚠️ Upgrade Guzzle dependency to ^7

Starting version 4.0.0, we have updated the dependency of guzzlehttp/guzzle from >= 5.3 to ^7, this is why we have also bumped a major version of the library itself.

The code is now adjusted to use Guzzle's new functions when building parameters similarly to the development versions 3.5.0 and 3.6.0.

If you have already updated the dependency in your code to one of those versions, upgrading to v4.0.0 should impose no more further changes.
