Greetings,

WCSLIB 4.18 is now available from http://www.atnf.csiro.au/~mcalabre.

This release implements the HEALPix polar or "butterfly" projection
with projection code "XPH".  A short article co-authored with Stuart
Lowe is also available.  It describes the projection, as well as
giving the projection equations and their inverses.
