Any reason why this is not merged?
Did you fixed it on an other commit?

[vishr]

I will review it today, it worked right?

[alexandrestein]

Yes, it was working with the previous release.

The pull request appears as not merged but I see all of it in the main branch.

Any reason why you didn't merged it?
In case I'm doing things wrong, I would appreciate to know what.
Other ways, no hard feelings.

@alexandrestein Somehow there was a merge conflict and I was not in a position to manually merge it. However, your changes are part of the latest release. I will take care of it from next time :). Thanks for your effort.

[alexandrestein]

All good, just wanted to know.
