The first fix appears to correct a bug where Driving Aid settings in performance files where not being properly detected.
For the 2nd fix i'll let the GpxPatch docs do the talking:
Advanced optionsSome options can only be specified in gpxset.ini. The first two are:
Number of consecutive cc's.Can be specified using a key named ConsecutiveCars under section [Misc]. It specifies how many computer cars can be out on the track at the same time in non-race sessions. As a player you can still go out anytime.
Fuel laps for cc's.Can be specified using a key named FuelLaps under section [Misc]. It specifies the number of fuel laps the computer cars will use in non-race sessions.
Both options can also be specified in seperate sections for each type of non-race session, so it's possible to use different settings per session.
The sections should be called like this: [FreePrac], [FriPrac], [SatPrac], [SatQual], and [Warmup]. It's also possible to use both [Misc] as default and only a few of the five specific sections as an override.
