+               <description>&lt;p&gt;A new version of the
+&lt;a href=&quot;https://tracker.debian.org/pkg/cura&quot;&gt;3D printer slicer
+software Cura&lt;/a&gt;, 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
+&lt;a href=&quot;https://ultimaker.com/en/products/cura-software/release-notes&quot;&gt;release
+notes&lt;/a&gt; for the list of bug fixes and new features.&lt;/p&gt; Version 3.2
+was announced 6 days ago.  We will try to get it into Debian as
+well.&lt;/p&gt;
+
+&lt;p&gt;More information related to 3D printing is available on the

-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
