The file... ftp://elsie.nci.nih.gov/pub/tzcode2010a.tar.gz ...is now available; this reflects the changes circulated last week on the time zone mailing list. Expect tzcode2010b.tar.gz in a week or two (to address the issues identified by kre last week). Happy first 2010 release :)
Both 2010a and 2010b are already in the tree, in testing (~arch).
