🔒 Lockfile

After every update, the local lockfile (lazy-lock.json) is updated with the installed revisions. It is recommended to have this file under version control.

If you use your Neovim config on multiple machines, using the lockfile, you can ensure that the same version of every plugin is installed.

If you are on another machine, you can do :Lazy restore, to update all your plugins to the version from the lockfile.
