Drupal 7 port, is based on version 6.1rc2.
It still has some bugs on ui, mostly on rules form, but you can use the module, and upgrade a site from Drupal 6 (if it use the version 6.1rc2 of the module).
Please report any issue you find so we can have a stable release with Drupal 7
Full field API support. Now, field data can be find by naming convention (drupal field name is used of metadata field name) or by setup.
This version has been tested width drupal rc1, rc2 and rc3 without any incompatibilities.
I Hope it should work with drupal 7 final release.
The last week has seen a flurry of activity that accounts for about half of the commits for the last 6 weeks. This is due in large part to the great number of patches contributed from other developers, giving me plenty to review and build on. This release contains more solid Entity / Rules / Views integration and an improved shopping cart workflow. It also contains my first uses of EntityFieldQuery and the Entity Metadata Wrapper, two critical APIs for building Fieldable Entity based systems. Once again all our SimpleTests pass, too, though we're still in need of a lot more.
The pièce de résistance of alpha 3 was the dynamic Add to Cart form, which has seen bug fixes in this release to address inconsistencies in the dependent attribute display. I'm not sure if I can top the awesomeness of that form in this release, but the Rules powered dynamic pricing system at least comes close.
