1) How soon until Fuse 3.3.1 will be released?
Within the next week.
2) Will Fuse-3.3.1 include Camel 1.3?
3) How hard would it be to include a newer version of Camel ( like 1.3) in Fuse 188.8.131.52?
I can't recall if there were API changes or not. I'd suggest just waiting for the FUSB ESB 3.3.1 to be released in the next week.
Fuse ESB 3.3.1 is tentatively scheduled to release either Friday or early next week. It will certainly be released with Fuse Mediation Router (Camel) 1.3.3 or 1.3.4. I'm not sure that we have tried to run Fuse ESB 184.108.40.206 with the newer Camel version, but I don't see any reason that you couldn't try to deploy the servicemix-camel component from Fuse ESB 3.3.1 to Fuse ESB 220.127.116.11.
Thanks for the info and I look forward to using the 3.3.1 release.
