FreeBSD 12.3-RELEASE Errata

Abstract

This document lists errata items for FreeBSD 12.3-RELEASE, containing significant information discovered after the release or too late in the release cycle to be otherwise included in the release documentation. This information includes security advisories, as well as news relating to the software or documentation that could affect its operation or usability. An up-to-date version of this document should always be consulted before installing this version of FreeBSD.

This errata document for FreeBSD 12.3-RELEASE will be maintained until the release of FreeBSD 12.4-RELEASE.

Introduction

This errata document contains "late-breaking news" about FreeBSD 12.3-RELEASE Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release. These other copies of the errata are located at https://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 12-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).
