v0.3 has been completed this morning. I've done a lot of code cleanup, on both a security and code standpoint. Instead of "assuming" data passed to the script from the database is "valid" for feeds, we run subjects through htmlentities (thus validating code) and we force "int" on fields which should only contain numbers.
I've repaired a problem with the offsets option introduced in 0.2 which allows you to split your one large sitemap into several easier to manage sitemaps (thus allowing you the opportunity to not go over the 50k link limit that some services enforce.
I have also built onto the offsets option and built in the ability to utilize a sitemap index which will list any "valid" sitemaps on from your forum (built using this script only); everything will be done automatically, all you need to do is submit the sitemap index into google (or a search engine which support them) and when you tell them to look at your site, they will grab your list of maps and work on them accordingly.
I have also set the "offsets" option to off by default; when I introduced it in 0.2 I set it to "on" by default.
Coming in 0.4:
I'm looking to add the ability to base "importance" to urls based on their date posted; this will allow the newer data to have a larger importance than the older data, thus allowing it to be crawled more often than older threads.
I'm also looking to allow the maximum thread inclusion to be adapted in the URL as well; however this ability will not be able to go over the scripts hardcoded 50k limit.
Also, if you've got a suggestion for expansion, please let me know, I'm always looking at new ideas.
If you're looking to upgrade, please email me (james[at]virtualnightclub[dot]net) with your licensed url's and I'll send off the new files.
If you're looking to purchase license please feel more than free to email me for more information.
