NetBSD 5.0_RC4 binaries available for download

In the immortal words of Dr. Zoidberg, "Hooray!"

Today, we have two things to be happy about.  First, the fourth release
candidate of NetBSD 5.0 is available for download.  Second, this
announcement, like RC3's, coincides with an important birthday: that of
Billy West.

Below are some highlighted changes since RC3:
- Added the RLIMIT_AS resource, which limits the total address space
  available to processes.
- Improved NFS server stability
- FFS improvements
- A fix for a pf(4) DoS
- re(4) now works with the RealTek 8111C, which is found on many current
  motherboards with Intel chipsets

As usual, src/doc/CHANGES-5.0 has the full details.

Binaries of 5.0_RC4 are available for download at

ftp://ftp.NetBSD.org/pub/NetBSD-daily/netbsd-5-0-RC4/

Those of you tracking by source can either continue following the netbsd-5
branch or use the netbsd-5-0-RC4 tag.

As always, we want your feedback.  This time, we are especially
interested in hearing from people who are using NFS.

IPv6 Prefix change for the NetBSD servers at ISC

Dear all,

just in case somebody has actual IPv6 addresses in use somewhere
instead of DNS names:

The IPv6 prefix for the NetBSD servers at ISC renumbers from
2001:4f8:4:7::/64 to 2001:4f8:3:7::/64.

best regards,
	spz

Summer of Code projects selected


For the fifth consecutive year, the NetBSD Project is proud to
participate in Google's Summer of Code program[1] as a mentoring
organization and we're pleased to announce the list of projects[2] that
have been accepted for this summer.  This year's selected students
include a number of NetBSD developers, returning SoC alumni and a few
freshmen.  We're very excited to have projects ranging from the areas of
filesystems over install automation to userland tools and we expect the
entire NetBSD community to benefit tremendously.

In the coming weeks, you will see our students engage the NetBSD
community for support with their projects; please give them a warm
welcome and help our developers, students and mentors lead all these
projects to success!

Announcing the NetBSD Project Blog

It is with great pleasure that I am able to officially announce the new 
NetBSD Project Blog:

  http://blog.NetBSD.org

The NetBSD Project Blog allows us to let you, the community, know about 
new developments in NetBSD and pkgsrc. The blog supplements our existing 
netbsd-announce mailing list and the "Recent Changes and News" webpage. 
We hope it will provide you with greater insight into the future of 
NetBSD.

For those that tweet - so do we - http://www.twitter.com/NetBSD

Announcing NetBSD 5.0

On behalf of the NetBSD developers, I am proud to announce that
NetBSD 5.0, the thirteenth release of the NetBSD operating system,
is now available.

NetBSD 5.0 features greatly improved performance and scalability on
modern multiprocessor (SMP) and multi-core systems.  Multi-threaded
applications can now efficiently make use of more than one CPU or core,
and system performance is much better under I/O and network load.

This improved performance is the result of a rewritten threading
subsystem based on a 1:1 threading model, new kernel synchronization
primitives, kernel preemption, a rewritten scheduler implementation,
real-time scheduling extensions, processor sets, and dynamic CPU sets
for thread affinity.  Almost all core kernel subsystems, like virtual
memory, memory allocators, file system frameworks for major file
systems, and others were audited and overhauled to make use of highly
concurrent algorithms.

In addition to scalability and performance improvements, a significant
number of major features have been added. Some highlights are: a preview
of metadata journaling for FFS file systems (known as WAPBL, Write
Ahead Physical Block Logging), the 'jemalloc' memory allocator, the
X.Org X11 distribution instead of XFree86 on a number of ports, the
Power Management Framework, ACPI suspend/resume support on many
laptops, write support for UDF file systems, the Automated Testing
Framework, the Runnable Userspace Meta Program framework, Xen 3.3
support for both i386 and amd64, POSIX message queues and
asynchronous I/O, and many new hardware device drivers.

For full details, please see the release notes at:
