Hm, interesting question at the Linux Mint forums:
"What ever happened to the update releases of mint 5? I've been waiting a year now, still no sign."
Because Mint 5 (Elyssa) is an LTS version, a point release would be a good thing for anyone who wants to install it at this stage. Otherwise, you're gonna have tons of updates to pull in. Ubuntu's Hardy Heron (their LTS version) has released a couple, I think. Even Mepis has released 8.0.06 and 8.0.10 this year.
So what's up at Mint? Not sure. Maybe a point release is just too much to ask, with everything else they have going on, like the Mint Debian project, among other things.
Here's one person's reply to the question above:
"If it's that important to you why not simply install the point two release of Hardy Heron, and from there install the mint tools and change your repos to that of Elyssa. This will give you the closest thing to an Elyssa point release as you are going to get."
Better yet, install the point two release of Hardy and forget about Mint until next time. If you're gonna go through all that trouble, I can't see any reason to bother with Mint at all -- I mean, Mint's a fine distro, but after all this time, I don't see any big advantages to running Mint instead of Ubuntu, and there might even be a few drawbacks.
But I have to say, for people like me who started out with Elyssa when it was fresh, and have kept it updated, we're in good shape. Of course, for someone who doesn't have it backed up, if you bork your system and have to reinstall, well... If that was me, of course I'd pass on Elyssa and move on. She'd understand. :-D
