		<summary type="html">&lt;p&gt;Created page with &amp;quot;{{Release|2.1|11 Apr 2016}}  === New features === * &lt;a href=&quot;/Installation#Checking_That_It_Works&quot; title=&quot;Installation&quot;&gt;Checking&lt;/a&gt; now classifies features to important/extra/experimental * Ability to bring...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Release|2.1|11 Apr 2016}}&lt;br /&gt;
&lt;br /&gt;
=== New features ===&lt;br /&gt;
* [[Installation#Checking_That_It_Works|Checking]] now classifies features to important/extra/experimental&lt;br /&gt;
* Ability to bring some disk files into images. See $source/scripts/tmp-files.sh&lt;br /&gt;
* C/R of&lt;br /&gt;
** Completed AIO requests&lt;br /&gt;
** Fallback gre and gretap net devices&lt;br /&gt;
&lt;br /&gt;
=== Optimizations/improvements ===&lt;br /&gt;
* Code coverage collecting now works&lt;br /&gt;
* Use native rtnl library for netlink messages processing&lt;br /&gt;
* Using &amp;lt;code&amp;gt;--output -&amp;lt;/code&amp;gt; now results in stdout as log, not a file with the name &amp;quot;-&amp;quot;&lt;br /&gt;
* Signals are printed by names in logs&lt;br /&gt;
&lt;br /&gt;
=== Fixes ===&lt;br /&gt;
* &amp;lt;code&amp;gt;Make tar&amp;lt;/code&amp;gt; generated tarbal with bad name&lt;br /&gt;
* CG restore code lacked rollback in some places&lt;br /&gt;
* Error code from raw syscalls was treated with errors resulting in wrong &amp;lt;code&amp;gt;criu check&amp;lt;/code&amp;gt; reports&lt;br /&gt;
* Dumping task with HUGE amount of file descriptors failed&lt;br /&gt;
* Task could be stopped after pre-dump if respective option was used&lt;br /&gt;
* A /proc/pid directory from dead process conflicting with a new alive one could cause dump to fail&lt;br /&gt;
* Zombie from alien session/process group caused restore to fail&lt;br /&gt;
* CGroup fs was wrongly mounted in CGNS on restore&lt;br /&gt;
* Irmap scan was mis-checking devices numbers&lt;br /&gt;
* Use-after-free in irmap scan&lt;br /&gt;
* Btrfs bindmounts detection was mistaken due to 'subvol=' options met&lt;br /&gt;
* Propagation of mountpoint's shared groups was lost for propagated mounts&lt;br /&gt;
* Unaligned allocations of restore shared memory could result in codedumps when used by futexes&lt;br /&gt;
* Temporary mountpoints could result in spurious propagations&lt;br /&gt;
* When aborting the dump criu could crash on use-after-free objects&lt;br /&gt;
* Locking the network could stuck doing the DNS resolve&lt;br /&gt;
* Several build fixes&lt;br /&gt;
&lt;br /&gt;
=== Deprecated/removed ===&lt;br /&gt;
* The images from criu prior to 0.4 are deprecated&lt;br /&gt;
* The &amp;lt;code&amp;gt;--namespaces&amp;lt;/code&amp;gt; option makes no sense and is also deprecated&lt;br /&gt;
* The &amp;lt;code&amp;gt;--ms&amp;lt;/code&amp;gt; option for check action is deprecated&lt;/div&gt;</summary>
