A new release will be released, don't worry. Currently work is being done in making daily builds available on the major platforms, such that every user do not have to rebuild themself, for easier testing. The new releases will be lightweight releases, meaing that you should grab a new release to update and no backports are made.
Also devbisme, the reason for not releasing stables, is there has not been enough resources to mandate time for such, and the goal is to provide nightly builds to ease the bug fixing and reporting for developers and users. So Chris, the goal is not that everyone should build from source as you suggest.
devbisme, there are some unittesting tests available in the qa directory which is using the python scripting to perform tests, currently only available to pcbnew, which is the most actively developed component currently. You are welcomed to design unit tests.
A contributing reason to no release for some is the KIWAY  work and other new features, that needed to stabilize a bit, which I mean they have. There are bugfixes in every week, the project is very active.
For the release policy see .
Also, as I understand it, the release will be after the new features form Tom is mergerd . In this regard, I will encourage people to donate via the donation page CERN has setup, specifically to support Tom and Maciej, not to forget the main developers of KiCad. There should be a mail from Wayne, indicating he wanted to wait with the release after  was achieved, but I can't locate it right now.
I do encourage people to try out the latest builds, and stop using the old stable.
