v2.3.9

• Reorganisation of the app's internal files to facilitate a new Linux build script.
• Dev menu item to do a live reload of the engines.json config file. (Requested by a certain Lc0 dev.)

v2.3.8

• Fix the common PGN issue where the last move is an illegal king move due to a digital board sensing a king going to a central square (which is how the players indicate the result). Previously such files would be rejected, but it's common enough (e.g. from Lichess live broadcasts) to be worth handling as a special case.

v2.3.7

• Fix an issue parsing certain Arena-exported PGN files (probably a rare issue but I did get a report).

v2.3.6

• Fixes an issue that would prevent the window from closing in the event that the renderer process crashes or hangs.

v2.3.5

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

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.

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).

v2.3.2

• Added experimental option in the Dev menu to accept lowerbound / upperbound info lines (e.g. from Stockfish).

v2.3.1

Fix a very dubious decision I made years ago about how to handle situations where the GUI was becoming laggy (e.g. due to opening some huge file or something). Previously some important user inputs might be dropped in such a situation; but now hopefully only unimportant user inputs will be dropped.

Tell me if you notice any lag (responsiveness issues) caused by this change.

v2.3.0

Added an option (in the Dev menu) to disable hardware (i.e. GPU) acceleration for Nibbler (the GUI itself, not the engine).

Electron apps such as Nibbler use hardware acceleration by default, but there's at least one report of this interfering with Leela's speed, since Leela also wants to use the GPU.
