It happened on Friday the 13th, August, 2010: OpenSolaris is dead, Oracle stopped the distro as well as the source code pushes to the repository. Read the full internal announcement, which leaked into the wild in the OpenSolaris mailinglist. What does this mean: No OpenSolaris 2010.05 or other updates will appear, you can buy Oracle Solaris 11 in 2011.

As mentioned here and as you can see on this page, there are a lot of interesting new features in the upcoming Solaris 10 10/08 or also called Solaris 10 Update 6 release:
Hope to hear more from Sun aboute the Update 6 and hope bits will be available for download, soon. Refering to this press release, Solaris 10 10/08 is scheduled to be available in mid-October.
UPDATE: Solaris 10 Update 6 is released on Halloween 2008 !
Look at the “What’s New in the Solaris 10 10/08 Release” Documentation and
Just tried to install Solaris Express Developer Edition 9/07 on a Dell Latitude D600 today. Wow, this was like installing MacOS on a Macbook, everything runs out of the box, display, ethernet, sound. Just have to check WLAN and BT, now.
See and hear more on project Webstack, PHP, Glassfish V2 on Solaris on YouTube.
At Pixelpark, we use Solaris 10 as main production plattform for all our customers. All our web hosting customers need basic open source components like apache httpd, tomcat, mysql. Some of them are also using php, some are using mongrels, other glassfish V2 and so on. We always try to use the latest version of these components for security reasons and if we build high performance Web Sites, for performance. Today Solaris 10 U4 is offering outdated versions of apache, mysql and no php. Only Postgresql is up to date with Solaris 10 U4 (GREAT !!). Because we often (daily..) have to install these optimzied and up to date versions we have a couple of choices: Download binary distributions (like coolstack or from blastwave) or build these components on our own.
We hope, that the Sun Webstack project will bring us precompiled, optimized and up to date apache httpd, php, mongrel Versions with security relevant updates, soon. Maybe future Solaris 10 Updates (U5) will bring newer version of these main Web2.0 components that we do not have to compile, test, distribute, patch the components on our own.
Solaris Express Developer Edition 9/07 is released and has a new installer! Great to see this update.
Download it or order a free DVD.
