There’s also a warning every time:

> julia\> using VulkanCore  
> [Info: Precompiling VulkanCore [16167f82-ea26-5cba-b1de-ed6fd5e30a11]  
> ┌ Warning: Package VulkanCore does not have Libdl in its dependencies:

> │ added Libdl as a dependency but haven’t updated your primary

> └ Loading Libdl into VulkanCore from project dependency, future warnings for VulkanCore are suppressed.

Should i make an issue on github, or is this normal?

Sorry, that’s an upgrade oversight.
