What does "split BC" mean?

Question

I found "BC break" in GitHub terms - what does this mean?

Answer 1

"BC break" usually means backward compatibility in general terms, but as David Schwartz said, it can be interpreted as breaking binary compatibility in some contexts.

Answer 2

A “break of BC” is a break of binary compatibility. Nokia documents it well in the compatibility review. This basically means that code developed with earlier versions of the compiler, library, or operating system will not work on devices or runtimes built using the newer version.
