I am not familiar with this, but saw that last time we updated this, we also had to update xlconnectjars. So not sure if that is required this time. Anyways, from what I can tell compared to https://github.com/miraisolutions/xlconnect/pull/96/files, the changes are consistent and make sense to me (but Martin or Roland should definitely review and approve).

Edit: Nevermind about xlconnectjars, I forgot we're not using that anymore.

@RolandASc I'll merge this tomorrow if you have not additional comments.
