A new version of ABC came out the other day, and it appears the web service got a few more information fields as well as the ability to stop torrents in addition to pausing them. There was also some renaming which broke existing versions of phpABC, so a new release has been created. It works with both PHP4 and 5. You’ll want to install it in a new folder.
Download phpABC 1.3
Update: This old version gets a lot more downloads than other outdated versions; I suspect it is because the blog entry has ABC 3.0 in the name. In case you have arrived here via search engine, phpABC is at version 2.1 as of October 2005 . Find out more at the phpABC homepage.
