The release notes for FreeBSD 7.0-CURRENT contain a summary of the changes made to the FreeBSD base system on the 7-CURRENT development line. This document lists applicable security advisories that were issued since the last release, as well as significant changes to the FreeBSD kernel and userland. Some brief remarks on upgrading are also presented.
This document contains the release notes for FreeBSD 7.0-CURRENT on the IA-64 hardware platform. It describes recently added, changed, or deleted features of FreeBSD. It also provides some notes on upgrading from previous versions of FreeBSD.
The snapshot distribution to which these release notes apply represents the latest point along the 7-CURRENT development branch since 7-CURRENT was created. Information regarding pre-built, binary snapshot distributions along this branch can be found at http://www.FreeBSD.org/snapshots/.
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 7.0-CURRENT can be found on the FreeBSD Web site.
This section describes the most user-visible new or changed features in FreeBSD since 5.3-RELEASE. In general, changes described here are unique to the 7-CURRENT branch unless specifically marked as [MERGED] features.
Typical release note items document recent security advisories issued after 6.0-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.
A new sysctl variable kern.malloc_stats has been added.
This allows to export kernel malloc statistics via a binary structure stream.
A new sysctl variable vm.zone_stats has been added. This
allows to export
uma(9) allocator
statistics via a binary structure stream.
The mpt(4) driver has been updated to support various new features such as RAID volume and RAID member state/settings reporting, periodic volume re-synchronization status reporting, and sysctl variables for volume re-synchronization rate, volume member write cache status, and volume transaction queue depth.
The
ifconfig(8)
utility now supports a -k flag to allow printing potentially
sensitive keying material to standard output. This sensitive information will not be
printed by default.
The libmemstat(3) library has been added. This is for use by debugging and monitoring applications in tracking kernel memory statistics. It provides an abstracted interface to uma(9) and malloc(9) statistics, wrapped around the binary stream sysctl variables for the allocators.
libpcap has been updated to v0.9.1 (release).
tcpdump has been updated to v3.9.1 (release).
Documentation of existing functionality has been improved by the addition of the following manual page: snd_t4dwave(4).
Important: Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files.
