Daydreamer 1.7
Daydreamer 1.7 (UCI), by Aaron Becker
http://github.com/AaronBecker/daydreamer
new download
I'm happy to announce a new release of my chess engine, Daydreamer. The biggest new features in 1.7 are support for Gaviota endgame tablebases and support for opening books in Polyglot (.bin) or Chessbase (.ctg) format. I've also overhauled and improved both search and evaluation, substantially improving Daydreamer's strength.
Thanks very much to Miguel Ballicora for making his excellent tablebases freely available, to Stephan Vermeire for getting me on the right track for ctg book support, and to Jim Ablett for providing optimized binaries for Windows and Linux. A more complete list of changes from 1.6 and thanks is available in the readme.

Re: Daydreamer 1.7
Thanks, Aaron.
Good to see an update to strong improving engine that fought well in the CCT's.
Is it possible to get back the feature with beautification of Pv lines, like it had in first version?

Re: Daydreamer 1.7
If you set the "Verbosity" option to anything above "low", it should print the fancier, SAN-style pvs in addition to the normal output.

Re: Daydreamer 1.7
Jim Ablett just pointed out that I accidentally uploaded a release candidate version instead of the final release. I have now replaced them with the proper files. Thanks Jim!
Unfortunately, due to some file caching issues on my host that I can't control, I couldn't just replace the old file with a new one, so I removed the old file in favor of this new link: new download. If a moderator could change the link in my first post, I'd appreciate it.

Re: Daydreamer 1.7
Aaron,
Version 1.7 lost this test-game on time.
After black's 22...Qg3 Daydreamer simply stopped responding.
Any idea?

Re: Daydreamer 1.7
I'm not sure. I run most of my testing games at game in 10s or 1.0s+0.1s and haven't seen any time-outs since the 1.61 release, so I'm guessing it's a bad interaction between the engine and GUI. What interface are you using?
edit: somehow I'm sure the answer will be Arena. Nothing ever works right for me in Arena.
