Hi. I'm currently upgrading my site from 1.5.3 to 1.5.5b.
I rely on the zones table rate shipping module, where I divide the states into eastern and western states, and have a graduated shipping cost based on the weight.
I noticed that the code for the other shipping modules has changed significantly, and I wonder if there are any recent updates to this module to keep things up to date with 1.5.5b. I didn't see any updates in the addons site since 2007, but perhaps some have been made and posted in this thread. I apologize if I didn't see it here, but there are 31 pages, and I might have missed it. I did do a search for "1.5.5" and for "zip" but didn't see anything.
I want to make sure that my site is up to date with all the latest security.
I do have another site that is running 1.5.5a, and this module is installed and seems to be working fine, but I just want to make sure I'm not introducing any security problems or other types of problems.

Thanks in advance for any help!
