First, if you look at this you'll see that the highest level of ODWEK that WEBi supports is V9.0:
http://www-01.ibm.com/support/docview.wss?uid=swg27038530There will be no separate EoS doc link for WEBi because WEBi was never sold as a separate license. WEBi was a bundled license,
bundled w/ CM842/843x and CMOD85/90.
So when the bundles went EOS, WEBi too went EoS.
WEBi went EoS with CM V8.4.x which was 4/30/2016.
And WEBi will go EoS with CMOD V9.0 on 9/30/2017.
