v1.5.9

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.5.9

v1.6.0


Some compatibility improvements for the upcoming Ceres 0.87.
A clickable halt button when the engine is running normally (thanks to @eahova)

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.6.0

v1.6.1

When Leela reports that it has spent 0 nodes analysing a move, display its winrate as "?" rather than "50%". Most noticably, this improves the display of losing moves in tablebase positions

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.6.1

v1.6.3

Fix another issue with Ceres compatiblity where the stated node count for a position would be wrong, causing absurd numbers and all possible arrows to appear.


Fix a compatibility issue with Ceres (the Leela-ish alternate engine) in locales where decimal numbers use commas.

Note that Ceres must be configured before use in Nibbler (try running Ceres in the console and answering its questions).

Also, for best results with Ceres, note that using an N-based arrow filter (Display menu --> Arrow filter) is strongly recommended.

v1.6.4

Improve behaviour of logfile menu item.
Remove arrow filtering by U (now using N instead). This works better for Ceres and arguably for Leela as well.

v1.6.5

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.6.5

No important change from RC 3.
To recap then, v1.6.5 is mostly an internal cleanup of how Nibbler communicates with the engine. There are also some very minor improvements to the GUI, barely worth mentioning.
The engine-comms rewrite seems to be working as far as I can tell, but do let me know of any issues, especially desynchonisation messages.
This version may or may not be more reliable for the upcoming Ceres 0.89.
Fix changing behaviour when receiving a "bestmove" due to node limit, if the search position was locked.
Minor improvements to display of M and D when such values are not known.
Better logging.
As far as I can tell, the engine-comms rewrite seems OK. Let me know if you have any issues, especially if you ever see any "desync" messages.

Rewrote the code that communicates with the engine. All being well, this should make it much harder for the engine and Nibbler to end up out-of-sync with each other.
However, this was a substantial change in logic, and one cannot rule out the possiblity of bugs...
If all is well, there should be no noticeable change for the user.

Nibbler v 1.6.6


https://github.com/fohristiwhirl/nibbler/releases/tag/v1.6.6

Display Ceres splash screen when using Ceres
Display tbhits in the infobar (only when a tablebase is loaded)
"Previous sibling" menu item, thanks to @Zenzizenzizenzike

v1.6.7

Option to display move numbers in PVs
Marginally better behaviour when using Stockfish (which remains Not Recommended)

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.6.7

NEW: v.1.8.0 is out

-Automatically stops the engine before setting options (could crash Stockfish otherwise).
-Restored the option to make the next actual move a unique colour.

https://github.com/fohristiwhirl/nibbler/releases/tag/v1.8.0

v2.0.2

-Drastically improve Polyglot loading speed (for example, by about 5000% in my case).
-Reduce memory usage for Polyglot books by about 80%.

https://github.com/rooklift/nibbler/releases/tag/v2.0.2

v2.3.3

Clicking the winrate graph and dragging the mouse left or right will now advance / backup the position as you'd expect. (It's not quite perfect if you drag quickly past the end, alas...)
Fix a bug in how the FEN handler deals with a certain type of illegal FEN.
By default, clear logfile upon opening it (but this can be changed in the menu).

https://github.com/rooklift/nibbler/releases/tag/v2.3.3

v2.3.4

Fix a bug in the "Draw PV on mouseover" feature when the only source of move information was an online API. Thanks to @dav1312 for the report.

https://github.com/rooklift/nibbler/releases/tag/v2.3.4

v2.3.5

Hopefully fixes a race condition that might occasionally cause the GUI's config files not to be saved correctly.
