Aquarium 4.0.7 update with Rybka 4.1 released

We are glad to inform you that Aquarium 4.0.7 update is released.

There are no major visible changes in it. But there are a lot of fixes inside. We were working hard and about a hundred of different fixes were done to provide this release.

Two important issues that were solved are:

  1. Minimax process in IDeA became times faster. This is especaily visible when you operate with a lot of positions (like 100 000 and more).
  2. Game analysis with large time control worked too fast in previous builds and didn’t provide expected quality.

Aquarium 4.0.6 Released

The long-awaited Aquarium 4.0.6 patch was finally released at the end of December. This is a huge update, involving more than one thousand changes, some of them major.

There is plenty of information available on the Internet about the new version, including several of my columns from last year. I think it’s time to give a high-level overview of this new version based on what has been written about it since the first hints of expected improvements appeared more than six months ago. The changes in the new version fall into these major categories:

  • New features, many of which have been described in previous ChessOK Cafe columns. I know that many users appreciated seeing their suggestions being implemented in this version.
  • Usability improvements, including a more responsive user interface and a more streamlined implementation of several features. Again, these changes were often based on user feedback.
  • Major redesign of the internal structure of important components of the program. These changes are not immediately obvious, but affect the ability of Aquarium to handle large amounts of data, improve performance of some time consuming operations, reduce resource requirements, decrease start up time when there are many open databases, games, IDeA projects, etc. Language support was also redesigned making, it easier to translate Aquarium to different languages.
  • And last but not least, bug fixes.
