In my project I have created various dev packages in the past. I’ve been working with mainly a couple packages lately (which depend on most older packages). As Julia get updated, these couple new packages get updated with the new version of Julia, now at 1.9.3. Today, I noticed my older packages are based on earlier versions of Julia, like 1.7.2, or 1.8.1, etc, shown in the toml files. But when I run the new packages with Julia 1.9.3, there is no report about problems with older packages (so I never noticed they are based on earlier Julia).
So my question is what is going on, or what should I do now?
