1. Introduction

This document contains the release notes for FreeBSD + 10.0-RELEASE. It describes recently added, changed, or + deleted features of FreeBSD. It also provides some notes on + upgrading from previous versions of FreeBSD.

The latest, up-to-date version of the release notes are + available online at http://www.FreeBSD.org/releases/10.0R/relnotes.html.

The snapshot distribution to + which these release notes apply represents a point along the + 10.0-STABLE development branch between 10.0-CURRENT and the + future 10.1-RELEASE. Information regarding pre-built, binary + snapshot distributions along this branch can be found at + http://www.FreeBSD.org/releases/.

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 - 10.0-RELEASE can be found on the FreeBSD Web site.

2. What's New

This section describes - the most user-visible new or changed features in FreeBSD - since 10.0-CURRENT. - In general, changes described here are unique to the 10.0-STABLE - branch unless specifically marked as MERGED features. -

Typical release note items - document recent security advisories issued after - 10.0-CURRENT, - 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.

2.1. Security Advisories

No security advisories.

2.2. Kernel Changes

The use of unmapped VMIO buffers eliminates the need to perform - TLB shootdown for mapping on buffer creation and reuse, greatly reducing the - amount of IPIs for shootdown on big-SMP machines and eliminating up to 25-30% - of the system time on i/o intensive workloads.

The maximum amount of memory the FreeBSD kernel - can address has been increased from 1TB to 4TB.

A new cpuset(2) API has been added - for thread to CPU binding and CPU resource grouping and - assignment. The cpuset(1) userland utility has been added - to allow manipulation of processor sets.

The ddb(4) kernel debugger now has an output capture - facility. Input and output from ddb(4) can now be captured - to a memory buffer for later inspection using sysctl(8) or - a textdump. The new capture command controls - this feature.

The ddb(4) debugger now supports a simple scripting - facility, which supports a set of named scripts consisting of a - set of ddb(4) commands. These commands can be managed from - within ddb(4) or with the use of the new ddb(8) - utility. More details can be found in the ddb(4) manual - page.

The kernel now supports a new textdump format of kernel - dumps. A textdump provides higher-level information via - mechanically generated/extracted debugging output, rather than a - simple memory dump. This facility can be used to generate brief - kernel bug reports that are rich in debugging information, but - are not dependent on kernel symbol tables or precisely - synchronized source code. More information can be found in the - textdump(4) manual page.

Kernel support for M:N threading has been removed. While + 10.0-RELEASE can be found on the FreeBSD Web site.
