Another release of OpenIndiana has just been published earlier this month, with some further improvements:
All OpenIndiana system software was rewritten in Python 3. Installation images now don’t deliver Python 2.7 interpreters or libraries, however some software still requires Python 2.7.
GCC compilers were updated to 7.5.0, 8.4, 9.3. GCC 7 is the default oi-userland compiler now.
Latest illumos-gate bits (45de87).
A lot of other bug fixes and minor software updates are included.
Will make it a focus to get the OpenIndiana VM going on my desktop this month - I really miss Solaris and would really like to see what it’s up to
