Hi all,
We're pleased to finally announce the pcp-3.7.0 release of PCP!
This is a fairly major release - the first release to support
IPv6, the first with SSL/TLS extensions to the PCP protocol,
and also contains many other improvements, fixes, and totally
new extensions.
Thank you to all of the people who have contributed. You can
find source and binary builds in the project download section.

We're looking forward to an even bigger next release, with work
already progressing on the new JSON/web interfaces, Python PMDA
interfaces, new tools, per-user security extensions, and more.
We also expect to have the first open version of the PCP books
in the next few weeks, thanks to collaborative efforts between
SGI and Red Hat - further details to follow.
