Webform support added to Drupal 7
Thanks for your patience as the Drupal 7 version of Fill PDF has undergone development.
I'm happy to report that Webform tokens were added back as of yesterday. They are now provided via an optional module called Webform Tokens.
See the Fill PDF project page for more details.
In light of this occasion, I've also created a 7.x-1.0-beta2 release of Fill PDF. Please try it out and report any issues or requests in the issue queue.
