I tried to register a package that contains:
```julia
[compat]
DiffEqBase = "<6.116.0"
Sundials = "~4.11"
```
and get the error message:
```julia
The following dependencies do not have a [compat] entry that is upper-bounded
and only includes a finite number of breaking releases: DiffEqBase
```
What is the best way to fix that? DiffEqBase 6.116.0 is broken, but older versions work. How can
I define this such that Julia registrator accepts it?

Probably something like `6.0.0-6.115` works. (You probably don’t want to support major versions lower than 6, do you?)
Ps. All versions after 6.116 are broken? In what sense? Wouldn’t it be better to fill a bug report in that case?

Thanks!
I filed a bug report [Release v6.116.0 breaks Sundials v4.11.4 · Issue #880 · SciML/DiffEqBase.jl · GitHub](https://github.com/SciML/DiffEqBase.jl/issues/880) but it is still open…

This doesn’t work:
```julia
DiffEqBase = "6.0.0-6.115"
```
But this works:
```julia
DiffEqBase = "6.0.0 - 6.115"
```
(Spaces are important).

Uhm… Maybe add some spaces?

I understand that should work, though.
This is from [the manual](https://pkgdocs.julialang.org/v1/compatibility/#Hyphen-specifiers):
```julia
PkgA = "1.2.3 - 4.5" # 1.2.3 - 4.5.*
```

Yes, we require the spaces before and after the hyphen.
