Using ${var} in strings is deprecated

Automatically closed - issue fixed for 2 weeks with no activity.

This is not yet fixed since the patch was not committed. This should be reopened. The patch looks good!

Appears to be fixed in dev branch: https://git.drupalcode.org/project/config_patch/-/blob/3.0.x/src/PluginM...

I think this was a duplicate report, maybe?

Issue was against 3.0.2 which will soon be 2 years old. People needed a patch. Can we get this tagged, please?
