<div dir="ltr"><div dir="ltr">Hey,<br></div><div dir="ltr"><div><br></div><div>This is actually not an uncommon misconception.

Obviously, for projects like nova, keystone, or devstack with large dependency lists, there's a huge amount of community pressure to keep them open as long as possible. (This is why there was controversy when Cinder wanted to close their EM branches; it would potentially force projects depending on it to also close their branches).</div><div><br></div><div>The way things are now, since that policy was updated:</div><div>(Disclaimer: the policy is written in the https link above; below is my understanding of it, not the policy itself.

Hopefully the recently-landed items to both change the name to "unmaintained" to reflect it's actual status as an old release with minimal maintenance and the opt-in barrier to reduce the incidences of branches dying a slow death without users knowing they are no longer in development.</div><div><br></div><div>Hope this helps,</div><div>Jay Faulkner</div><div>Ironic PTL</div><div>TC Vice-Chair</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Aug 24, 2023 at 7:27 AM Thomas Goirand <<a href="mailto:thomas@goirand.fr">thomas@goirand.fr</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">On 8/23/23 22:21, Jay Faulkner wrote:<br>

In fact, this makes me question how it works in OpenStack in general. It <br>
feels like many projects are doing their ways, and deprecating old <br>
branches in different ways. Sometimes, this happens when a CVE can't be <br>
addressed in a proper way.<br>
<br>
So I wonder: what's the promised lifecycle of a release, and why this is <br>
different depending on the project? Aren't we committed to maintain at <br>
last the latest 3 releases? If so, then deprecating any branch before <br>
Yoga is currently fine, no? If so, why are projects keeping stable <br>
branches opened for longer?<br>
<br>
Cheers,<br>
