Oooo! Just realized that I didn't upload yesterday's work on HURL. Now version 22.214.171.124 is available on Hackage! But if you don't want to depend on xml-conduit for resolving URLs you can turn this new feature off at build time.
NOTE: Hackage packages have two major version numbers, one of which should be incremented whenever I change, rather than add to, an existing API. Which I usually do to support more of The Web, and shouldn't (but might) break any callers.
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
