[chessx-developer] ChessX 1.6.6

[jens-chessx <jen...@gm...>]

Dear users and developers,

I have updated the setup files for ChessX to 1.6.6
This was mainly triggered by some incompatible changes from Apple regarding installation under Tahoe (Mac OS 26),
but there are also some new features like reading and writing to Lichess Studies.

I hope, you will find this update helpful 

Kind regards 

Jens
