+OpenRC NEWS
+
+This file will contain a list of notable changes for each release.
+
+OpenRC-0.13.2
+=============
+
+A chroot variable has been added to the service script variables.
+This fixes the support for running a service in a chroot.
+This is documented in man 8 openrc-run.
+
+The netmount service now mounts nfs file systems.
+This change was made to correct a fix for an earlier bug.
+
+OpenRC-0.13
+===========
+
+/sbin/rc was renamed to /sbin/openrc and /sbin/runscript was renamed to
+/sbin/openrc-run due to naming conflicts with other software.
+
+Backward compatible symbolic links are currently in place so your
+system will keep working if you are using the old names; however, it is
+strongly advised that you migrate to the new names because the symbolic
+links will be removed in the future.
+Warnings have been added to assist with this migration; however, due to the
+level of noise they produce, they only appear in verbose mode in this release.
+
+The devfs script now handles the initial mounting and setup of the
+/dev directory. If /dev has already been mounted by the kernel or an
+initramfs, devfs will remount /dev with the correct mount options
+instead of mounting a second /dev over the existing mount point.
+
+It attempts to mount /dev from fstab first if an entry exists there. If
+it doesn't it attempts to mount devtmpfs if it is configured in the
+kernel. If not, it attempts to mount tmpfs.
+If none of these is available, an error message is displayed and static
+/dev is assumed.
+
+OpenRC-0.12
+===========
+
+The net.* scripts, originally from Gentoo Linux, have
+been removed. If you need these scripts, look for a package called
+netifrc, which is maintained by them.

-As of OpenRC-0.13, two binaries have been renamed due to naming

+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ * A singly-linked list is headed by a single forward pointer. The
+ * elements are singly linked for minimum space and pointer manipulation
+ * overhead at the expense of O(n) removal for arbitrary elements. New
+ * elements can be added to the list after an existing element or at the
+ * head of the list.  Elements being removed from the head of the list
+ * should use the explicit macro for this purpose for optimum
+ * efficiency. A singly-linked list may only be traversed in the forward
+ * direction.  Singly-linked lists are ideal for applications with large
+ * datasets and few or no removals or for implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.
