upgrading from previous versions of FreeBSD. </p><p xmlns="http://www.w3.org/TR/xhtml1/transitional">This distribution of FreeBSD

<span xmlns="http://www.w3.org/1999/xhtml" class="quote">&#8220;<span class="quote">late-breaking</span>&#8221;</span> information discovered late in the
release cycle or after the release. Typically, it contains

to documentation. An up-to-date copy of the errata for FreeBSD
11.2-RELEASE can be found on the FreeBSD Web site. </p><p xmlns="http://www.w3.org/TR/xhtml1/transitional">This document describes the most user-visible new or changed

described here are unique to the 11.2-STABLE branch unless
specifically marked as MERGED features. </p><p xmlns="http://www.w3.org/TR/xhtml1/transitional">Typical release note items document recent security
advisories issued after 11.1-RELEASE, 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 practices. Clearly
the release notes cannot list every single change made to FreeBSD
between releases; this document focuses primarily on security
advisories, user-visible changes, and major architectural
improvements. </p></div><div class="sect1"><div xmlns="" class="titlepage"><div><div><h2 xmlns="http://www.w3.org/1999/xhtml" class="title" style="clear: both"><a id="upgrade"></a>2. Upgrading from Previous Releases of FreeBSD</h2></div></div></div><p xmlns="http://www.w3.org/TR/xhtml1/transitional">[amd64,i386] Binary upgrades between RELEASE versions
