No.  Only with 2.1 tehre is the new keybox format (pubring.kbx) which
will be used for new installations but an existing pubring.gpg from pre
2.1 will be used if it exists.

At the next write access to the keyring v3 keys are removed.

David send me one of his mails privately without mentioning that he also
send he to the ML :-(.  I looked at it anyway; see below.

You are about to export the same key iwtice.  Unless special options are
used the --export command exports the main key "sec" and all subkeys
"ssb".  Not a problem but may be surprising.

You played with the new ECC algorithms but not a problem.

You wrote output to the file "allow-non-selfsigned-uid" ;-)

I can't see an error message. "can't handle public..." are just warnings
about some othe keys found in the keyring or your key?

It seems that you have ECC subkeys on your key or signed a key woth an
ECC key.  I can't check that because the keyservers do not yet all
support ECC.

> "Key 0xAAD8C47D not found or not valid. The (sub-)key might of expired."

Please send me your complete key.  The copy from the keyservers might
not be complete.  --export is sufficient.


Salam-Shalom,
