As part of my new drive to better understand how WSO is being used, I’ve added a couple of tweaks to WSO, Userlookup and the SSOClient code. Userlookup and SSOClient will now send version numbers back to WSO whenever they do anything. As I get people to upgrade to new versions, I can keep track of who has and has not upgraded so that I know where I stand in terms of compatibility. Obviously not everyone uses the Java code, but I can keep a reasonable idea of how they are using WSO by looking at the User-Agent header that gets sent with web requests to WSO. So, from SSOClient 1.5.3 and Userlookup 1.4.2 onwards, I can track version numbers so I would encourage everyone to please upgrade as soon as you can. Thanks Kieran
