Although 1.7.0 also has the bug, which is still allowed by this compat. But this will let the CI pass at least. 1.8.0 is fine.

Alternatively, we could just bump to 1.10.0, as that's the LTS. 1.6.6 is just the most conservative bound.

I'm fine with bumping to 1.10

[DilumAluthge]

Is there any release of 1.7.x that fixes the bug?

If the answer is no, then let's just bump to 1.8 (assuming that 1.8.0 fixes the bug).

IMO no need to drop support for 1.8 and 1.9 if we aren't forced to.

I'm going to bump the Julia compat in #64 to 1.8 and see if the CI passes with the added git-lfs tests over there

Edit: All tests passed on Julia 1.8.0 (the Julia min tests)

[mortenpi]

Is there any release of 1.7.x that fixes the bug?

On that branch, it looks like it got fixed in 1.7.3.

[mortenpi]

Not really important, but I wonder if it was an unintended side-effect of this PR: JuliaLang/julia#44212

[mortenpi]

Trying out an overly complicated compat here. But I'm also quite content with just 1.8.0 minimum (so feel free to close this).

[DilumAluthge]

I'm always a fan of keeping support for old Julia versions, so I like this.
