Sorry, nothing new here:

Maelstrom releases were already announced.

Chameleon is on the waiting list for the XB/UCI chronology with this comment:

Code: Select all

Chameleon	currently just slightly above a random mover - waiting for an official WIN release	

I compiled it for myself on 2022-07-17 (WIN) because there is no Win release currently and this is a PV from startpos:

Addendum:

This new program escaped my perpetual github search, because the terms 'engine' and 'uci' are missing in the about section.
(they are there though in the readme, which is not indexed for the search criteria)

Minic 3.26

should be more or less Minic 3.26 dev targeted at TCEC mainly
(compiled versions only at the Minic-Dist folder)

Yes I give that for TCEC next event as 3.25 is already quite an Elo jump.
But I'm still having some more patches to merge and test so I don't release yet for rating list.
I know testing is quite expensive in time and resources and I don't want to release to often.
