The latest release as I write this is Version 3.05 (April 27, 2017), and
the Version 3.06 beta was released on April 28, 2017. Mike is still
actively involved in the NetRexx community.

​I have NetREXX installed. But, as Mr. Crayford indicated, it is not a
replacement for TSO REXX in a TSO environment. I have, on occasion, used it
to write a "batch" program or a UNIX command line program. I can't do this
much here because we are MSU constrained and don't have an zIIP (or zAAP)
on our z9BC. ​So I get "dinged" if I show up on my boss's MSU radar

Right! But if you had a JIT compiled classic REXX it would save you money!  But that won't happen. For starters it would need to be a rewrite in C++ with a VM. It's no secret I'm a Lua fan and it interested me that an IBM JIT developer has an experimental project that JIT enables Lua 5.3 using OMR https://github.com/Leonardo2718/lua-vermelha. I could use that to "supercharge" Lua on z/OS. But there just doesn't seem to be much appetite for new languages on z/OS. Old dogs new tricks I suppose.
