Ancestry Updates "Canada, Soldiers of the First World War, 1914-1918"

An Ancestry.ca update to the "Canada, Soldiers of the First World War, 1914-1918" database is announced. A search will provide name, birth date, birth location, name of relative and, regiment number. Click to see the attestation paper - remember there are two sides.
A small but increasing number of full service records are at the Library and Archives Canada website, but not linked from Ancestry.
The comment I recently made about a LAC blog post applies here too: when such databases are updated please tell us how much is changed so we know whether the effort to repeat previously unsuccessful searches is likely to be worthwhile.
