:Is that primarily coders or users? For me I want to switch my servers to 
:DF but I am kind of waiting for a new release version where only the 
:bugs and exploits are updating but no more code is introduced.
:I think that overall from what I see on my test server DF is production 
:ripe but I'm overly paranoid when dealing with productivity machines.
:I'll planned to jump the ship from 4 to DF in July 2005 ( a matter of 
:backup and reinstalling the OS) do you think there will be new release 
:by then?

    Yes, there will probably be a release in February and probably another
    one just before USENIX (the USENIX timing seems to garner the most 
    community interest).

    I understand the issue of release stability and the necessity of
    branching the tree to achieve that.  I'm holding off on that as long
    as possible because the moment we branch the tree we have to start
    dealing with two branches instead of one.  I know we'll have to do it
    eventually, and I can certainly think of ways to reduce the burden
    (i.e. as you say, making the branches bug-fix-only trees instead of
    tested-stable-feature trees).  I definitely have no intention of creating
    parallel development paths, that would be a disaster waiting to happen.

    I don't know *when* we will do our first branch, however.
