Because of a bug A-rating updates were not saved for a whole day, so everything was recalculated once again.
I took this opportunity and added an extra column to the match results to keep track of the previous rating values and the change, which are now both visible in the match results. Note that Glicko r and RD are floating point numbers internally, so there may be rounding errors in the UI when you look at your match history.

The web page was changed to show the Glicko interval (rating +/- deviation) instead of a single number (rating-deviation).
This was done to make the display consistent with the numbers minqlx now receives for the "!elo" and "!balance" commands.
The API used to return r-RD, but that has a bias to underrate players, so it was changed to pure "r".
Due to this change the displayed rating numbers are higher now.
