@jnavila any links to StackOverflow discussions or other documentation about this change?

Well, first of all my own prose 😆 : https://jnavila.github.io/plotkicadsch/ , but more seriously, there's an explanation for the life cycle of -cache.lib and -rescue.lib files here or here

[bartlettD]

This is the right move, the -rescue.lib file is needed for schematics drawn with the Eeschema tool in KiCAD to resolve symbols when those symbols dissapear or are modified from the Global or Project libraries.

Ideally, a user should never have a -rescue.lib because symbols will never dissapear or wont be changed, but sometimes a change to the library may break a design an so a "rescue" is a safer option.

The KiCAD docs explain this in a bit more detail.
