When I `dev local path/to/my_pkg` and `using Revise`, changes to the source of `my_pkg` are reflected as expected in my session (`REPL` or `Jupyter`) but when I run `status` I see the old version of `my_pkg` listed there — i.e. the old version number.

I’m not sure this matters much, since the code itself is being tracked, but I’m still a bit puzzled (a) whether the discrepancy means anything and (b) how to resolve it. (I’m guessing something line `update` will accomplish b?)

(Also this seems to be related to some [puzzling behavior I was seeing](https://discourse.julialang.org/t/messed-up-environment-uuid/64651) when I changed file names.)

`pkg> resolve` updates to the current version number in the `dev`’d packages `Project.toml`. But it does not mean anything. The code is tracked either way.

I see, so for a `dev`ed package `resolve` (when using `Revise`) all that happens is that that number gets changed. How does that differ from `update`?

You are right: `pkg> update MyPkg` also increments the version number. But then again: it does not do anything. What matters is what you fix the version number at when you `add MyPkg` later. Until then, the version numbers really don’t do anything.
