	commit 98119dc991b95052e80c647b1d6ccc59705c7729

This release is from STABLE-BRANCH-1-2 branch.

I's a release for minor bug fixes.  It fixed a bug for key generation
introduced in the previous release.  Now, too/upgrade_bypasswd.py has
a check if configuration matches.


It's April, new school year started in Japan.  For those who try, new
algos (Ed448 and X448) are available in master.  I think I'm going to
remove RSA from master soon.
