v5.1 The bitmap graphics from the US Macintosh release of Lancelot
now display correctly.
v5.0 V1 games are also now supported.
The input logic now correctly handles commas and full stops
in the user's input for v3 or later games.
The input logic now allows hyphens and apostrophes to be
input, which is needed for some v2 games.
The dictionary listing for v2 games no longer has junk on the
end.
The graphics detection algorithm has been improved, so that it
now correctly finds graphics in all known games.
A difference in the logic between the v2 and v3 line-drawn
graphics has been implemented, which corrects the scaling for
some v2 graphics.

v4.1 Corrected a bug that made Lancelot unplayable.
BBC B bitmaps are now shown as they appeared on the original
computer.
