But you have to pay $200 for the document that lists changes from last draft
to first official version.
(Ok, Ok, it was just a joke. But you do get the point.)

Unfortunately, being an ISO standard, to obtain it costs 118 CHF (about
$110 USD). Hard to follow a standard you can't afford to read. Is there
an online version somewhere?

WARC File Format Published as an International Standard
http://netpreserve.org/press/pr20090601.php
ISO 28500:2009 specifies the WARC file format:
* to store both the payload content and control information from
mainstream Internet application layer protocols, such as the
Hypertext Transfer Protocol (HTTP), Domain Name System (DNS),
and File Transfer Protocol (FTP);
* to store arbitrary metadata linked to other stored data
(e.g. subject classifier, discovered language, encoding);
* to support data compression and maintain data record integrity;
* to store all control information from the harvesting protocol
(e.g. request headers), not just response information;
* to store the results of data transformations linked to other
stored data;
* to store a duplicate detection event linked to other stored
data (to reduce storage in the presence of identical or
substantially similar resources);
* to be extended without disruption to existing functionality;
* to support handling of overly long records by truncation or
segmentation, where desired.
