 This file will contain a list of notable changes for each release. Note
 the information in this file is in reverse order.
 
-## OpenRC-0.18.3
-
-Modern Linux systems expect /etc/mtab to be a symbolic link to
-/proc/self/mounts. Reasons for this change include support for mount
-namespaces, which will not work if /etc/mtab is a file.
-By default, the mtab service enforces this on each reboot.
-
-If you find that this breaks your system in some way, please do the
-following:
-
-- Set mtab_is_file=yes in /etc/conf.d/mtab.
-
-- Restart mtab. This will recreate the /etc/mtab file.
-
-- Check for an issue on https://github.com/openrc/openrc/issues
-  explaining why you need /etc/mtab to be a file. If there isn't one,
-  please open one and explain in detail why you need this to be a file.
-  If there is one, please add your comments to it. Please give concrete
-  examples of why  it is important that /etc/mtab be a file instead of a
-  symbolic link. Those comments will be taken into consideration for how
-  long to keep supporting mtab as a file or when the support can be
-  removed.
-
-## OpenRC-0.18
-
-The behaviour of localmount and netmount in this version is changing. In
-the past, these services always started successfully. In this version,
-they will be able to fail if file systems they mount fail to mount. If
-you have file systems listed in fstab which should not be mounted at
-boot time, make sure to add noauto to the mount options. If you have
-file systems that you want to attempt to mount at boot time but failure
-should be allowed, add nofail to the mount options for these file
-systems in fstab.
