Topple 0.7.4 released yesterday
https://github.com/konsolas/ToppleChess/releases
Pulse 1.7.0 and 1.7.1 were released in November and were not mentioned yet
https://github.com/fluxroot/pulse/releases
There are daily/hourly updates for Demolito at the appveyor link below
https://ci.appveyor.com/project/lucasar ... to/history
I will compile a new Sapeli 1.67 today
GoogleplexStarthinker had a lot of commits in the last weeks,
probably a new release coming soon, or may be I compile a dev version
Also several (important) changes for Delocto since the last release 2018,
a new compile would make sense...

Ok, both are available now at my site.
The Googleplex_Starthinker dev version calls itself 1.7 beta2

Hi Volodymyr,
I noticed v2.3.0 became v2.2.1 with Skill Levels, followed quickly by v2.2.2 but Skill Levels are gone, back to Levels, is that correct?
Al.

Hey Scally,
Yes, it is correct. I was not sure about my changes I did in 2.2.1 (being in a hurry for a TCEC S17 start deadline, so doing some things in a rush), so I reverted those risky changes and introduced another (less risky) changes in Igel 2.2.2.
Everyone is advised to use 2.2.2 in testing instead of 2.2.1.
