A general description is here.
In R 3.0.0, ‘identify()’ and ‘locator()’ did not record information correctly, so replaying a graph (e.g. by copying it to another device) would fail. (PR#15271)
Calling ‘file.copy()’ or ‘dirname()’ with the invalid input ‘""’ (which was being used in packages, despite not being a file path) could have caused a segfault.
‘unzip(list = TRUE)’ returned ‘Names’ as a factor and not a character vector (as documented) for the internal method. (Noticed by Sean O'Riordain.)
