+ <description><p>A new version of the
+<a href="https://tracker.debian.org/pkg/cura">3D printer slicer
+software Cura</a>, version 3.1.0, is now available in Debian Testing
+(aka Buster) and Debian Unstable (aka Sid). I hope you find it
+useful. It was uploaded the last few days, and the last update will
+enter testing tomorrow. See the
+<a href="https://ultimaker.com/en/products/cura-software/release-notes">release
+notes</a> for the list of bug fixes and new features.</p> Version 3.2
+was announced 6 days ago. We will try to get it into Debian as
+well.</p>
+
+<p>More information related to 3D printing is available on the
+<a href="https://wiki.debian.org/3DPrinting">3D printing</a> and
+<a href="https://wiki.debian.org/3D-printer">3D printer</a> wiki pages
+in Debian.</p>

-<p>Several of these research papers are based on data collected from
-hundred thousands or millions of disk, and their findings are eye
-opening. The short story is simply do not implicitly trust RAID or
-redundant storage systems. Details matter. And unfortunately there
-are few options on Linux addressing all the identified issues. Both
-ZFS and Btrfs are doing a fairly good job, but have legal and
-practical issues on their own. I wonder how cluster file systems like
-Ceph do in this regard. After all, there is an old saying, you know
-you have a distributed system when the crash of a computer you have
-never heard of stops you from getting any work done. The same holds
-true if fault tolerance do not work.</p>
-
-<p>Just remember, in the end, it do not matter how redundant, or how
-fault tolerant your storage is, if you do not continuously monitor its
-status to detect and replace failed disks.</p>
