found in the same location as the release notes (either as a part of a

&os; distribution or on the &os; Web site). It contains important

information regarding the advantages and disadvantages of using

&os; &release.current;, as opposed to releases based on the &os;

4-STABLE development branch.</para>

<para>All users are encouraged to consult the release errata before

installing &os;. The errata document is updated with

<quote>late-breaking</quote> information discovered late in the

release cycle or after the release. Typically, it contains

information on known bugs, security advisories, and corrections to

documentation. An up-to-date copy of the errata for &os;

&release.current; can be found on the &os; Web site.</para>

new drivers or hardware support, new commands or options,

major bug fixes, or contributed software upgrades. They may also

list changes to major ports/packages or release engineering

change made to &os; between releases; this document focuses
