The Solaris Coolstack team have announced some important changes that impact on the future of the popular open source software stack. In a nutshell, they are combining their Cool Stack software (intended for use with Solaris 10) with their Web Stack software (intended for use for OpenSolaris) into a single software bundle, which will be known as Sun Web Stack.
Not only will this new stack be supported on Solaris 10 and OpenSolaris, but Linux support is also being added, as is full support for those using the software in production a capacity.
The first version of Sun Web Stack is scheduled for release in November 2008 and will follow the version numbering from Coolstack. Thus, the first release will be Sun Web Stack 1.4.
