Links to each update are provided at:



<year> - is the last two digits of the year.
<release> - is a two digit number of the release within the year

Client-side software may also obtain a list of available packages by accessing the output from this script:


By default output is provided in XML format and contains all available metadata fields. The output can be restricted with the following CGI parameters:

output=XML|TAB - to define the output format

fields=type|release|date|format|url|size|md5 - hyphen-separated list of required fields, from "type", "release", "date", "format", "url", "size", "md5".
