@sfmskywalker Have the build dependencies been fixed so this can merge?

[sfmskywalker]

Not yet, main is still out of date. Current focus lies with 3.6.0, but I’ll try to update main when I get a chance.

[mcook-dev]

@sfmskywalker Anything I can help with regarding 3.6.0?

[sfmskywalker]

Not at the moment, but I appreciate the offer and will keep this in mind, thank you!

[mcook-dev]

@sfmskywalker no merge? that's upsetting

[sfmskywalker]

@mcook-dev Not sure how this was closed, but I don’t think it was intentional. Let me reopen.
