-
Add tooltip on top menu items
-
Fix bug in Analysis Board related to annotation box (ticket #140)

Render widgets with selected move format in the Analysis Board

Automatically persist requested engine data while viewing an analysis in the Analysis
Board (even if requested by another user than the analysis owner)

in WXF for example.
2024-03-24
2024-03-23
-
Fix the bug where the
wrong PV would be associated to FENs. Clean up existing analysis data. Not super clear how it happens

2024-03-18
-
Fix the bug where after
clicking on PV line in the Analysis Board, clicking again on the PV line would

-
Minor UI changes to the admin UI

2023-10-07

rated.

smaller k value when you solve it correctly - depending on how long ago you last played it, spread linearly
on 90 days, i.e. the k value is 8 instead of 16 if you solved it 45 days ago)

Upload more games to the Database, totalling 92,000.
2023-06-03
-
Replace logarithmic eval calculation by a more simple linear calculation in Analysis
Board. The new calculation caps cp at 7,706 which seems to be the actual maximum (except for 31,753 but
there is nothing in-between). CP is then normalize to a 0-100 scale.
-
Make the engine result data more understandable in the Analysis Board. It would only
show data for evaluation that had a CP value, and nothing for "mate in N" results. Sometimes it would also
show the data for the previously selected move, which didn't make sense. In the future, it would be
interesting to persist engine result data that don't contain a CP value.

data.
2023-05-20

Export PGN with variations with a nested structure instead of a flat list of lines/variations. However, we
might keep both types of exports later.
