I want to update a package to the most recent version. For some reason, the most recent version does not seem to be recognized. Here is an example using an empty environment: (@v1.6) pkg> st Status `~/.julia/environments/v1.6/Project.toml` (empty project) (@v1.6) pkg> add DifferentialEvolutionMCMC @v0.5.11 Resolving package versions... ERROR: Unsatisfiable requirements detected for package DifferentialEvolutionMCMC [607db5a9]: DifferentialEvolutionMCMC [607db5a9] log: ├─possible versions are: 0.1.0-0.5.9 or uninstalled └─restricted to versions 0.5.11 by an explicit requirement — no versions left When I add without specifying a version, v0.5.9 is installed: (@v1.6) pkg> st Status `~/.julia/environments/v1.6/Project.toml` [607db5a9] DifferentialEvolutionMCMC v0.5.9 What would cause this to happen?

Much appreciated. Thank you for the link.
