{{crtools|0.3|11 Dec 2012}}
=== New features ===
* C/R of [[Advanced_usage#Shell_jobs_C.2FR|shell jobs]]
* [[Advanced_usage#Link_unlinked_files_back|Handle]] files, that are opened and unlinked, but some other hard link exists
* More SOL_SOCKET socket options. Two most interesting are:
** Binding socket to device (<code>SO_BINDTODEVICE</code>)
** Per-socket packet filter (<code>SO_ATTACH_FILTER</code>)
* Shutdown state of a socket
* Task scheduler parameters (nice, policy and prio)
* Properly handle [[COW]] pages
* Memory mapped packet sockets (with SOL- options this is enough for tcpdump tool support)
* Complementary groups (<code>getgroups(2)</code>)
* Various mapping features, configured with <code>madvise(2)</code>
* Tune TCP sockets support to work with IPv6 sockets
* Closed (or not yet connected/bound) unix sockets
=== Bug fixes and improvements ===
* Print timestamps in log files
* Restructure source tree a little
** PIE stuff in separate dir
** Arch-specific code in arch/<Arch>/ directory
* Nicer <code>show -c</code> output for pages/pipes/etc contents
* Fixes in help text
* Save and restore blocked signals mask for threads
* Don't dump (and warn about it) corked UDP sockets
* Fixed livelocks when restoring too big socket queues
* Refresh info about sockets, that might have changed between diag dump and actual process freeze
* Lost file params and socket options for some unix sockets
* Fix inotify on opened and unlinked files
* Fix shared anonymous memory detection
* Properly close all files before restoring them
* Fixes in running external tools (ip/tar)
* Several fixes in control tty restoring code
* RT signals handlers dumped and restored
