 This file will contain a list of notable changes for each release. Note
 the information in this file is in reverse order.
 
+## OpenRC 0.33
+
+This version removes the "service" binary which was just a copy of
+"rc-service" provided for compatibility.
+
+If you still need the "service" binary, as opposed to "rc-service", it is
+recommended that you use something like Debian's init-system-helpers.
+Otherwise, just use "rc-service" in place of "service".
+
+## OpenRC 0.31
+
+This version adds support for Control Groups version 2, which is
+considered stable as of Linux-4.13. Please see /etc/rc.conf for
+documentation on how to configure control groups.
+
+## OpenRC-0.28
+
+This version mounts efivars read only due to concerns about changes in
+this file system making systems unbootable.  If you need to change something
+in this path, you will need to re-mount it read-write, make the change
+and re-mount it read-only.
+
+Also, you can override this behavior by adding a line for efivars to
+fstab if you want efivars mounted read-write.
+
+For more information on this issue, see the following url:
+
+https://github.com/openrc/openrc/issues/134
+
+## OpenRC-0.25
+
+This version contains an OpenRC-specific implementation of init for
+Linux which can be used in place of sysvinit or any other init process.
+For information on its usage, see the man pages for openrc-init (8) and
+openrc-shutdown (8).
+
+## OpenRC-0.24.1
+
+This version starts cleaning up the dependencies so that rc_parallel
+will work correctly.
+
+The first step in this process is to remove the 'before *' from the
+depend functions in the clock services. This means some  services not
+controlled by OpenRC may now start before instead of after the clock
+service. If it is important for these services to start after the clock
+service, they need to have 'after clock' added to their depend
+functions.

+reason. The way to deal with this will be different for each system.

+stopped, by using:

+```
+# rc-service someservice cgroup_cleanup

+.Nd the parent of all processes
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+.Nm
+is an init process which can be an alternative to sysvinit or any other
+init process.
+.Pp
+To use
+.Nm
+configure your boot loader to invoke it or symlink it to /sbin/init.
+Also, you will need to use
+.Xr openrc-shutdown 8 ,
+to halt, reboot or poweroff the system.
+.Pp
+The default runlevel is read from the init command line, the
+rc_default_runlevel setting in rc.conf, the kernel command line, or it is
+assumed to be "default" if it is not set in any of these places.
+.Pp
+.Nm
+doesn't manage getty's directly, so you will need to manage them another
+way. For example, you can use the agetty service script as described in
+agetty-guide.md in this distribution.
+.Sh BUGS
+This was first released as part of OpenRC 0.25.
+I do not know of any specific issues. However, since this is the first
+release of openrc-init, please test and report any issues you find.
