v1.7.4

• Filter out terrible moves when displaying arrows for A/B engine.
• Configurable via Display --> Arrow filter (A/B)

v1.7.3

• Fix focus buttons sometimes not appearing when they should.

v1.7.2

• Various minor improvements to the infobox and arrows.
• Inactive searchmove (a.k.a. "focus") buttons are now hidden when a search is running; this helps prevents PV misclicks. To add a searchmove you must now stop the engine. (Behind the scenes, changing searchmoves has always required this anyway.)

v1.7.2-rc1

• Various improvements when using A/B engines.
• Fix a rare desync issue.
• Always show all legal moves in the infobox.
• Obsolete info from A/B engines (from an earlier time in the search) will be grayed out.
• Option to display depth (for A/B engines only).

Some big internal changes to accomodate this; some chance of bugs; release candidate; blah blah blah.

v1.7.1

• Additional minor improvements when displaying Stockfish info.
• There's still more work to do, probably expect a 1.7.2 and more, soonish.

v1.7.0

• Makes Nibbler work more-or-less correctly with Stockfish and maybe other A/B engines.
• Nothing magical can be done about the fact that MultiPV is inherently crippling to A/B engines, but you can choose a low MultiPV value (see the menu item Dev --> A/B MultiPV). This menu item does not affect Leela.
• Filtering arrows is disabled for A/B engines; the number of arrows will be the MultiPV choice.
• In several ways the overall experience is still nicer with Leela.

v1.6.9

• Slightly faster PGN loading.
• Fix an issue with PVs when using Stockfish (which remains Not Actually Supported) in MultiPV = 1 mode .

v1.6.9-rc1

• The ability to load a PGN book for use in "Play" modes. This is slightly experimental.
• The use of a fairly small book (a megabyte or so) is recommended, since loading times are not the best.

v1.6.8

Changed some of the draw code. May improve visual quality when using certain custom piece sets.

v1.6.7

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