The Shen site will go completely open source with
the publication of Shen/tk 39/2 which will include
the IDE and the concurrency package. This will
complete the transfer of the last of the technology
developed under Shen Professional (SP).
SP was born in September 2015 as an incubator for Shen
technology and it proved very successful in this regard.
Whereas the kernel went open source in February 2015,
SP was forked off as closed source commercial product.
As such the revenue stream for SP provided an incubator
for some important work; the new S kernel, an IDE, concurrency
and graphics for Shen all came from SP.
The transfer of this technology began in 2021 and I indicated
that eventually all the technology under SP would transfer to
OS and that time has now arrived. SP will not be further developed
but will continue to run. Many thanks to those who supported
SP because you saved the Shen project.
Shen/tk 39/2 will more than replace SP because it essentially
levers SP technology and, unlike SP, the IDE is type secure and
is platform independent. This means that Shen/tk 39/2 will run
under SBCL and Chez Scheme. The latter, as you know is superlatively
fast , about 4X faster than SBCL. We also hope to have downloadables
for Linux and Mac/OS.
