</div>I think the pragmatic solution here is to roll a platform point-release,<br>
just fixing the particular major bug.<br>

<div class="gmail_extra">* Package maintainers cannot always get version bumps they need. The text example I gave is a perfect case: I would not expect the HP team to turn around and release a brand new HP to improve compile times of my users. But persistent users would have liked to be able to opt-in to getting that update, even if it meant recompiling everything.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">Perhaps we need to think about this as OSes do. Ubuntu will release version 12.04 (LTS), and then provide security patches as necessary. When enough security patches come in, they'll ultimately create a point release and then go through the effort of spinning a new CD. We're in a trickier situation due to the ABI issues, but I don't think we can solve this by simply forgoing interim updates and requiring a new point release for every fix we need.</div>
