abcl-1.6.1 release candidate for ELS2020 rc0

[Mark Evenson]

Rejoice! for the Bear has emerged from its Lair to slough off
a release candidate for abcl-1.6.1 <urn:abcl/1.6.1#rc0> 

Currently, the release candidate rc-0 committed to cloud builds; we
will be rendezvousing with the cryptographic signatures to do the
actual public release on Monday, live "at" ELS 2020.

Please get any outstanding github pull requests in before April 27,
2020 to be included in the release.  We should now be able to accept
pull requests while preserving your github identity if you are so
inclined.  Otherwise pseudo-anonymous patches are still solicited via
this mailing list.
