The final release candidate for the 4.2.0 version of Octave has been
uploaded to ftp://alpha.gnu.org/gnu/octave/.

Please download, build, and then run 'make check' (Linux, Mac) or
'__run_test_suite__' (Windows) to see how the new version performs.

I tested octave-4.2.0-rc4.tar.lz on Ubuntu 15.04 and it passed with zero
failures.

I tested octave-4.2.0-rc4-w32-installer.exe on a Windows XP virtual machine
and it passed with zero failures as well.
