I’ve recently tagged new versions of two of my packages, [JuLIP.jl](https://github.com/libAtoms/JuLIP.jl) and [NeighbourLists.jl](https://github.com/libAtoms/NeighbourLists.jl), and all hell has broken loose now in my small package eco-system. I would be grateful for any help in unravelling this. I performed my updates in the following steps (tagging new versions via Registrator):

- to begin, I had `JuLIP@v0.7.2` and `NeighbourLists@v0.4.1`
- I made some updates to both, then tagged `NeighbourLists@v0.5.0`
- I then tagged `JuLIP@v0.8.0`
- I then fixed the compatibility on the `JuLIP.jl` `v0.7.x` branch and. tagged `JuLIP@v0.7.3`

This is when my problems started. I suspect my problems can be reduced to understanding the following issue:

- I use the package manager to create a “fresh” environment:

```julia
] generate test
] activate test
] add JuLIP

```

- For some reason, `JuLIP@v0.7.3` is installed and not `v0.8.0` =\> Why?

There seems to be some incompatibility between `JuLIP` and `NeighbourLists`. I can see this, when I try to `] free JuLIP` in my `v1.1` environment. I then get the following error message:

```julia
ERROR: Unsatisfiable requirements detected for package NeighbourLists [2fcf5ba9]:

```

I don’t understand this, since `JuLIP@v0.8.0` and `NeighbourLists@v0.5.0` should be compatible:

```julia
# JuLIP/Project.toml
[compat]
NeighbourLists = "≥ 0.5.0"
julia = "1"

# Neighbourlists/Project.toml
[compat]
julia = "0.7, 1"

```

See also the relevant files in the Registry:

- [https://github.com/JuliaRegistries/General/tree/master/J/JuLIP](https://github.com/JuliaRegistries/General/tree/master/J/JuLIP)

update: I tried again on a clean Julia system, and same problem (`v0.7.3` as opposed to `v0.8.0`) occurs.

</div>

The problem is this entry

[https://github.com/JuliaRegistries/General/blob/f6b0c57970958a4911c0226a2e7830ee1ead7819/J/JuLIP/Compat.toml#L79-L80](https://github.com/JuliaRegistries/General/blob/f6b0c57970958a4911c0226a2e7830ee1ead7819/J/JuLIP/Compat.toml#L79-L80)

It says that all versions between of JuLIP from 0.7.3 up to 1.0 are only compatible with NeighbourLists 0.3-0.4. Then the next entry

[https://github.com/JuliaRegistries/General/blob/f6b0c57970958a4911c0226a2e7830ee1ead7819/J/JuLIP/Compat.toml#L82-L83](https://github.com/JuliaRegistries/General/blob/f6b0c57970958a4911c0226a2e7830ee1ead7819/J/JuLIP/Compat.toml#L82-L83)

has looser compatibility but the previous one is still valid. This seems like a bug in the script that produces the PR to the General registry.

Any chance this is related to reversing the order of tags?

</div>

As a temporary fix should i just tag another version 0.8.1 of JuLIP?

That’s not gonna help because the bad compat entry will still be there.

```julia
["0.7.3-0"]
NeighbourLists = "0.3-0.4"

```

Should be changed to something like

```julia
["0.7.3"]
NeighbourLists = "0.3-0.4"

```

</div>

I see - so I should manually fork the `General` registry, make the change and make a PR?

Yes, that is one option, or just use the GitHub UI. But you can make the change locally first and see that things behave like they should after the change.

thanks - the change worked locally. I made the PR via the GitHub UI as you suggested.
