It describes recently added, changed, or deleted features of FreeBSD. It also provides some notes on upgrading from previous versions of FreeBSD. + +This distribution of FreeBSD 11.1-RELEASE is a release distribution. It can be found at `https://www.FreeBSD.org/releases/` or any of its mirrors. More information on obtaining this (or other) release distributions of FreeBSD can be found in the link:{handbook}#mirrors[Obtaining FreeBSD' appendix] to the link:{handbook}[FreeBSD Handbook]. + +All users are encouraged to consult the release errata before installing FreeBSD. The errata document is updated with "late-breaking" 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 FreeBSD 11.1-RELEASE can be found on the FreeBSD Web site. + +This document describes the most user-visible new or changed features in FreeBSD since 11.0-RELEASE. In general, changes described here are unique to the 11.1-STABLE branch unless specifically marked as MERGED features. + +Typical release note items document recent security advisories issued after 11.0-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. + +[upgrade]] +== Upgrading from Previous Releases of FreeBSD + +[amd64,i386] Binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=freebsd-release-ports[freebsd-update(8)] utility. The binary upgrade procedure will update unmodified userland utilities, as well as unmodified GENERIC kernels distributed as a part of an official FreeBSD release. The http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=freebsd-release-ports[freebsd-update(8)] utility requires that the host being upgraded have Internet connectivity. + +Source-based upgrades (those based on recompiling the FreeBSD base system from source code) from previous versions are supported, according to the instructions in `/usr/src/UPDATING`. + +[.important] +*Important*: + +Upgrading FreeBSD should only be attempted after backing up _all_ data and configuration files. + +[[security-errata]] +== Security and Errata + +This section lists the various
