Thanks for the updates.

Please be sure to tag the issue that this is addressing in the PR description (something like "Closes #xxxx".) Or at least make sure that it is linked in the "Development" section.

I won't be clicking Approve because we need approval from someone with more knowledge about this area of the code than I have.

@farzonl maybe? Or he could nominate someone else.
