I seem to recall that Daniel Mehrmann was considering taking his Fruit fork private, but I'm not sure.

Fruit reloaded 15A was a spontaneous idea because i noticed the 15th birthday here on talkchess.com.
It's a public version of course. I don't created a own thread and this is probably the reason why it wasn't notice so fast.

Here is the thread which include the download link of Fruit reloaded 15A:

Igel 2.8.0 at https://github.com/vshcherbyna/igel/releases/tag/2.8.0 (binaries for Windows).

This release brings major improvements in strength due to a fix of a null move pruning bug. A tiny code change brings +54 elo at LTC (http://chess.grantnet.us/test/7463/). An updated Night Nurse net from Dietrich Kappe brings additional 10-20 elo.

For discussions/questions about this version please use thread at http://talkchess.com/forum3/viewtopic.p ... 85#p862285

What's new:

- Fix null move pruning bug (54 elo)
- Use 250cp as lazy eval threshold
- Improve time management for sudden death time controls
- Use Dietrich Kappe's Night Nurse improved net (internal version ninu-0.2.5b.nnue)

Regression tests against Igel 2.7.0 indicate:

+75 elo at 10+0.1
+120 elo at 10+0.0 (sudden death time control)

Upon running it Windows Defender issued a warning that it might be harmful for my PC. I ignored the warning. To tell the truth Windows Defender does the same with almost all new chess programs.
I noticed that if I compile a source myself I never get a warning.

Version 21 of Stash released: https://gitlab.com/mhouppin/stash-bot/-/releases/v21.0

This version mostly consists of a large tuning of eval features.
Huge thanks to Andrew Grant for his paper on Ethereal's tuning method and his "quiet" dataset.
I didn't measure precisely the rating improvements, but based on SPRT results, my guess would be that Stash now plays above the 2600 Elo bar.
