Platform IO used to always work as expected, only building the files that were altered or dependent upon an edited file.
Of late it is always re-building all my source files despite only changing some lines of source in one file.
The only real change I can think of is the new V4.0.0 core (since updated to V4.0.2).
Is my platform IO file deficient in some area, causing the full rebuild?
