I did some further testing this git version converts \[ \]
But not equations eqnarray etc.
The strange thing when I use the version shipped by the package system
which is org-20171116, a date posterior to July 2017, then equations are
converted. However I thought the package system does not ship the latest
master but a stable release. So I am a bit confused.
Anybody know about the issue of exporting eqautions and eqnarray and
recent changes in the filters?
