subscriptions 5.x-2.3

Subscriptions 2 for Drupal 5.x has been rewritten from the ground up by chx and salvis, starting in November 2007 and completing in April 2008. Ongoing development has proceeded through 12 beta versions and one release candidate. We wish to thank the community for your continued testing and feedback, which helped to bring Subscriptions 2.0 into its present form.

The prior version 1.9 was known to be buggy beyond repair and has been unsupported since 2007. Subscriptions 2.0 provides an upgrade path that migrates all the information of a working 1.9 installation. As it creates completely new tables, it saves your 1.9 tables as {subscriptions_old} and {subscriptions_holding_old}; you can delete these tables after completing the upgrade.

Upgrading large sites from 1.9 to 2.x:
If your site has a large number of users, upgrading may take considerable time: depending on where you start, progress may quickly go to 80% or beyond, but it may take minutes or even hours to complete update 7, because update 7 loads and saves every user record in your database.
