Formatting.jl is being deprecated

[mattiasvillani]

I get the message below in Julia 1.10.1. MCMCChains.jl is the responsible package since:

pkg> why Formatting
MCMCChains → Formatting

Formatting
│ ┌ Warning: DEPRECATION NOTICE

│ │ If you are not using Formatting.jl as a direct dependency, please consider

I assume you're not using the latest version of MCMCChains (6.0.6) since that one does not depend on Formatting anymore (#451). Can you check whether updating MCMCChains fixes the issue?

Yes, you are correct, another package was holding me back at MCMCChains v5.7.1. When installing 6.0.6 in a fresh environment, I do not get the Deprecation notice. Thanks for the rapid response!
