As a package is a collection of functions, and as "base" is not used to
refer to the base package but to all packages that form "base R" (so utils,
graphics, stats, methods, parallel, ...), the functions in the parallel
package are one example of functions incorporated in "base R" from a
package. Actually two, because the functions in parallel are based on both
snow and multicore.

This has no relation to changes in implementation (which often don't happen
due to back-compatibility issues in edge cases).

Kind regards
Joris
