One of the current efforts under way in the dev list is driven by Tom Fennelly et al, who is working on introducing a series of small ball improvements to the user interface in Jenkins. If this is something you are interested in (and who aren't?), you should see Kevin Burke's manifest that sets out the plan of attack, and This mega thread on the dev list for the discussion.
There are numerous sub-conversations born out of this, and one of them is the minimum required servlet spec version for Jenkins.
Jenkins devs are thinking about ways to update page contents post load, for example so that the list view will keep updating as stuff happens. WebSocket was discussed as an option, and then server-side events, which seems to be the current favorite.
If you will be on the US East Coast or in Berlin for JUC, some of the JUC sponsors are organizing separate events called Continuous Delivery Seminar, which might be of interest to you. These events focus more on higher-level business value questions as well as vendor solutions that are difficult in community-focused JUC.
Read more about the events here. The events are free and I've heard that there'll be some souveniors. I'm one of the speakers, and I'll be talking about Jenkins, as always!
Let me start by introducing myself, my name is Steven Christou. Many of you might know me on IRC as schristou, my github id as christ66, or my twitter handle @schristou88. In Jenkins, I am currently working on some significant improvements to the subversion-plugin, along with various random bug fixes. I am also the current maintainer of Cobertura, an open source code coverage tool for java. Prior to working on Jenkins, I was working on Hudson at the Eclipse Foundation.
