August 04 2001: Released v0.90 of Astro::Cosmology. More tests (thanks Brad) and change in internal structure of module to (hopefully) make it more CPAN friendly. No functional changes to v0.83.
Available from CPAN.
August 02 2001: Released v0.84 of Astro::Cosmology (minor reorganisation, no functional change to v0.83).
August 01 2001: Released v0.83 of Astro::Cosmology (added version method, renamed string to stringify, documentation & test improvements).
July 29 2001: Released v0.82 of Astro::Cosmology (added STERADIAN to the constants and improved documentation).
Added v0.51 of the PDL Astro package. This is only of interest if you have a lot of scripts that use PDL::Astro::Cosmology and want to find them, but still have them work.
July 28 2001: Released v0.81, which is the first released version in the Astro::Cosmology namespace. The Constants module has been removed from the distribution: currently a number of useful constants are provided but it would be better if there were an Astro::Constants module (see the Astroconst package).
July 23 2001: Intention is to rename to Astro::Cosmology, then release to CPAN. This won't happen until some time in August.
July 19 2001: First "official" release to the public (v0.5).

v0.5 of the PDL::Astro module: PDL-Astro-0.50.tar.gz (15 kb).
