Chaser Retired


You may (or may not) have noticed that WebChaSeR now has acquired capabilities that, so far, had only been available in classic Chaser: lists of positions, search ranges, access to supported products (and more). It also provides access to ERs.

Maintenance of Chaser have become too costly. As a result, it was retired on 1 April 2013.
