FreeBSD 13.0 发布-Linuxeden开源社区

The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 13.0-RELEASE. This is the first release of the stable/13 branch.

Some of the highlights:

The clang, lld, and lldb utilities and compiler-rt, llvm, libunwind, and libc++ libraries have been updated to version 11.0.1.
Removed the obsolete version of the GNU debugger that was installed to /usr/libexec for use by crashinfo(8). Detailed kernel crash information can be obtained by installing modern GDB from ports or packages.
Removed the obsolete binutils 2.17 and gcc(1) 4.2.1 from the tree. All supported architectures now use the LLVM/clang toolchain.
The BSD version of grep(1) is now installed by default. The obsolete GNU version that was the previous default has been removed.
Removed CU-SeeMe support from libalias(3).
The qat(4) driver has been added, supporting some of the cryptographic acceleration functions of the Intel QuickAssist (QAT) device. The qat(4) driver supports the QAT devices integrated with Atom C2000 and C3000 and Xeon C620 and D-1500 platforms, and the Intel QAT Adapter 8950.
Several deprecated drivers have been removed.
Several drivers have been ported to the PowerPC64 architecture.
The kernel now supports in-kernel framing and encryption of Transport Layer Security (TLS) data on TCP sockets for TLS versions 1.0 through 1.3. Transmit offload via in-kernel crypto drivers is supported for MtE cipher suites using AES-CBC as well as AEAD cipher suites using AES-GCM. Receive offload via in-kernel crypto drivers is supported for AES-GCM cipher suites for TLS 1.2. Using KTLS requires the use of a KTLS-aware userland SSL library. The OpenSSL library included in the base system does not enable KTLS support by default, but support can be enabled by building with the WITH_OPENSSL_KTLS option
The 64-bit ARM architecture known as arm64 or AArch64 is promoted to Tier-1 status for FreeBSD 13.
And much more…

Availability

FreeBSD 13.0-RELEASE is now available for the amd64, i386, powerpc, powerpc64, powerpc64le, powerpcspe, armv6, armv7, aarch64, and riscv64 architectures.

FreeBSD 13.0-RELEASE can be installed from bootable ISO images or over the network. Some architectures also support installing from a USB memory stick. The required files can be downloaded as described in the section below.

SHA512 and SHA256 hashes for the release ISO, memory stick, and SD card images are included at the bottom of this message.

PGP-signed checksums for the release images are also available at:

A PGP-signed version of this announcement is available at:

The purpose of the images provided as part of the release are as follows:

dvd1

This contains everything necessary to install the base FreeBSD operating system, the documentation, debugging distribution sets, and a small set of pre-built packages aimed at getting a graphical workstation up and running. It also supports booting into a “livefs” based rescue mode. This should be all you need if you can burn and use DVD-sized media.

Additionally, this can be written to a USB memory stick (flash drive) for the amd64 architecture and used to do an install on machines capable of booting off USB drives. It also supports booting into a “livefs” based rescue mode.

As one example of how to use the memstick image, assuming the USB drive appears as /dev/da0 on your machine something like this should work:

# dd if=FreeBSD-13.0-RELEASE-amd64-dvd1.iso \
    of=/dev/da0 bs=1m conv=sync
