   3 CHANGES WITH 39:
   4         * This is mostly a test release, but incorporates many
   5           bugfixes.
   6
   7         * New systemd-cgtop tool to show control groups by their
   8           resource usage.
   9
  10         * Linking against libacl for ACLs is optional again. If
  11           disabled, support tracking device access for active logins
  12           goes becomes unavailable, and so does access to the user
  13           journals by the respective users.
  14
  15         * If a group "adm" exists, journal files are automatically
  16           owned by them, thus allow members of this group full access
  17           to the system journal as well as all user journals.
  18
  19         * The journal now stores the SELinux context of the logging
  20           client for all entries.
  21
  22         * Add C++ inclusion guards to all public headers
  23
  24         * New output mode "cat" in the journal to print only text
  25           messages, without any meta data like date or time.
  26
  27         * Include tiny X server wrapper as a temporary stop-gap to
  28           teach XOrg udev display enumeration. This is used by display
  29           managers such as gdm, and will go away as soon as XOrg
  30           learned native udev hotplugging for display devices.
  31
  32         * Add new systemd-cat tool for executing arbitrary programs
  33           with STDERR/STDOUT connected to the journal. Can also act as
  34           BSD logger replacement, and does so by default.
  35
  36         * Optionally store all locally generated coredumps in the
  37           journal along with meta data.
  38
  39         * systemd-tmpfiles learnt four new commands: n, L, c, b, for
  40           writing short strings to files (for usage for /sys), and for
  41           creating symlinks, character and block device nodes.
  42
  43         * New unit file option ControlGroupPersistent= to make cgroups
  44           persistent, following the mechanisms outlined in
  45           http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
  46
  47         * Support multiple local RTCs in a sane way
  48
  49         * No longer monopolize IO when replaying readahead data on
  50           rotating disks, since we might starve non-file-system IO to
  51           death, since fanotify() will not see accesses done by blkid,
  52           or fsck.
  53
  54         * Don't show kernel threads in systemd-cgls anymore, unless
  55           requested with new -k switch.

  60 CHANGES WITH 38:
  61         * This is mostly a test release, but incorporates many
  62           bugfixes.
  63
  64         * The git repository moved to:
  65           git://anongit.freedesktop.org/systemd/systemd
  66           ssh://git.freedesktop.org/git/systemd/systemd
  67
  68         * First release with the journal
  69           http://0pointer.de/blog/projects/the-journal.html
  70
  71         * The journal replaces both systemd-kmsg-syslogd and
  72           systemd-stdout-bridge.
  73
  74         * New sd_pid_get_unit() API call in libsystemd-logind
  75
  76         * Many systemadm clean-ups
  77
  78         * Introduce remote-fs-pre.target which is ordered before all
  79           remote mounts and may be used to start services before all
  80           remote mounts.
  81
  82         * Added Mageia support
  83
  84         * Add bash completion for systemd-loginctl
  85
  86         * Actively monitor PID file creation for daemons which exit in
  87           the parent process before having finished writing the PID
  88           file in the daemon process. Daemons which do this need to be
  89           fixed (i.e. PID file creation must have finished before the
  90           parent exits), but we now react a bit more gracefully to them.
  91
  92         * Add colourful boot output, mimicking the well-known output
  93           of existing distributions.
  94
  95         * New option PassCredentials= for socket units, for
  96           compatibility with a recent kernel ABI breakage.
  97
  98         * /etc/rc.local is now hooked in via a generator binary, and
  99           thus will no longer act as synchronization point during
 100           boot.
 101
 102         * systemctl list-unit-files now supports --root=.
 103
 104         * systemd-tmpfiles now understands two new commands: z, Z for
 105           relabelling files according to the SELinux database. This is
 106           useful to apply SELinux labels to specific files in /sys,
 107           among other things.
 108
 109         * Output of SysV services is now forwarded to both the console
 110           and the journal by default, not only just the console.
 111
 112         * New man pages for all APIs from libsystemd-login.
 113
 114         * The build tree got reorganized and a the build system is a
 115           lot more modular allowing embedded setups to specifically
 116           select the components of systemd they are interested in.
 117
 118         * Support for Linux systems lacking the kernel VT subsystem is
 119           restored.
 120
 121         * configure's --with-rootdir= got renamed to
 122           --with-rootprefix= to follow the naming used by udev and
 123           kmod
 124
 125         * Unless specified otherwise we'll now install to /usr instead
 126           of /usr/local by default.
 127
 128         * Processes with '@' in argv[0][0] are now excluded from the
 129           final shut-down killing spree, following the logic explained
 130           in:
 131           http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
 132
 133         * All processes remaining in a service cgroup when we enter
 134           the START or START_PRE states are now killed with
 135           SIGKILL. That means it is no longer possible to spawn
 136           background processes from ExecStart= lines (which was never
 137           supported anyway, and bad style).
 138
 139         * New PropagateReloadTo=/PropagateReloadFrom= options to bind
 140           reloading of units together.
