Clarify differences between Drupal 6 and Drupal 7 versions on Project page

Those blocks have been entirely replaced by Views versions in D7 and as a result that variable can no longer be used, so it got removed. Generally the release notes are a good place to find things. However, the D7 version of the module still doesn't have a stable release and so I haven't written up the full list of changes between D6 and D7 yet. When the code stabilizes and a stable release is available, then a more detailed list of changes will be provided.

Users upgrading from Drupal 6 will have to test and modify their setup, but they have to do that anyway with any major release upgrade. Users already on an old dev version of D7 should be unaffected as the use of Views was one of the initial changes, or if they are, they should know how to cope because dev versions are just that, "dev" versions and are used at your own risk.

FYI, here is the commit: http://drupalcode.org/project/faq.git/commit/6679ffa and the commit message was more verbose than you referenced: "Removed some blocks and replaced them with Views versions; Added some example views listings". That change was made back in August, just before the first RC release.

Hope that helps.

At the least, this section on the project page, should probably be updated to state that that it applies to only the D6 version:

There are 3 blocks included in this module. The first shows a list of FAQ categories. The other two can show a configurable number of FAQs - one shows recent FAQs, while the other just displays random ones.

An addition to the section on upgrade warning to include some of the content from #1 above, would be great also.
