[FieldTrip] Different results with source reconstruction from July 2018 and onwards

Hello all,

I get different results with the same source reconstruction code when using
Fieldtrip before 11 July 2018 compared to 12 July 2018. The results I get
from before the twelfth seems to be more in line with previous found
intracranial results and measurements on sensor level. I'm using eLORETA
and the code is basically the same as this:

The 'pre' attached file is how the first trial for the first participant
look with the version before july 11 and the 'post' is after july 11.

 - Operating System:  Windows 10 and Mac os:x Mojave
 - MATLAB version: R2019a
 - FieldTrip version: fieldtrip-171478a3e1c71f499ad0cf01f661dbb257ff5eb5
and fieldtrip-d1aa34272c61454dbbd9684f836c68b2dd26f337

What was it that justified such a huge change in the model? Can I read
about it somewhere? Note that this is not the problem described in
https://github.com/fieldtrip/fieldtrip/issues/1020 but appeared in an
earlier version.

Best regards
