Release notes:
- IN THIS RELEASE (1.6.7)

• Starting from this version Chess Studio is able to manage large PGN databases which can cause slowdowns or, in some cases, closure of the application. These large databases are managed in indexed mode so the impact on memory is practically zero. The user is warned when attempting to open a Database
• Fixed some errors that caused the application to behave abnormally.
• Minor bug fixes, improvements and optimizations.

- LAST UPDATES

• The new version of the Stockfish 16 engine has been integrated with the support of Neural Networks (NNUE). According with the authors in self-play against Stockfish 15, this new release gains up to 50 Elo and wins up to 12 times more game pairs than it loses.

• The functionality of Folding/Unfolding of variants has been added. In a game the variants can all be closed to improve the readability of the game itself. They can be opened as needed. This feature can be turned on or off in the general application settings.

• The new section dedicated to personal databases on the Cloud is available. As in the iOS version, you can create your own databases on the Cloud and populate them with games. You can create as many Databases as you want, for example each with a theme that interests you, and upload the games that are most significant to you. Obviously the Databases are also visible from the iOS version of Chess Studio and vice versa.

• The new version of the Stockfish 15.1 engine with the support of the Neural Networks (NNUE) has been integrated.

• The Opening Books section has been introduced. In order to create an opening book it is necessary to start from a database by clicking with the right mouse button and selecting "Create Opening Book".

• A new section dedicated to the most important tournaments both in progress and completed in the last year has been added. From this section the user can download the games played in the Tournament, can view the website and the results relating to the Tournament.
• New option to show Win-Draw-Loss (WDL) probabilities when the engine is analyzing. Enable WDL with the appropriate button or from the menu bar.

• The interface that contains the moves of a game has been modified and enhanced. The default settings have been changed but the interface is completely configurable by the user. You can change the colors of the background and the moves. There are ten types of figurines to represent the pieces. You can view a game in compact mode or with a high degree of indentation, you can adjust margins, line spacing and alignment. It is possible to insert fully configurable diagrams within a game (you can set pieces, board border and coordinates).  And much more! As always, you can set the parameters relating to the single game or relating to the entire application. The former are not permanent, the latter are saved by the application.

• It is now possible to transfer games from one database to another by copying/pasting or by dragging the selected game from one database to another. The copy/paste can be done either by clicking on the game selected with the right mouse button, or by using the actions from Menu, or by using the buttons in the database window.
