It looks like at least 2, and possibly 3, changes are being made;
1. Their modifying the candidate lists to remove certain
characters and change how things are displayed, which
will have an impact.
2. They're adding more shielding (I think this is some ferrites
around the cable bundle connecting the LCD), which apparantly cuts
the vurlnerable distance from 25m to 5m.
3. There is speculation that they are installing jammers too,
which will emit EM noise on the same frequencies.
