GnuPG 2.1.0 改进内容包括：

- The file "secring.gpg" is not anymore used to store the secret
  keys.  Merging of secret keys is now supported.

- All support for PGP-2 keys has been removed for security reasons.

- The standard key generation interface is now much leaner.  This
  will help a new user to quickly generate a suitable key.

- Support for Elliptic Curve Cryptography (ECC) is now available.

- Commands to create and sign keys from the command line without any
  extra prompts are now available.

- The Pinentry may now show the new passphrase entry and the
  passphrase confirmation entry in one dialog.

- There is no more need to manually start the gpg-agent.  It is now
  started by any part of GnuPG as needed.

- Problems with importing keys with the same long key id have been
  addressed.

- The Dirmngr is now part of GnuPG proper and also takes care of
  accessing keyserver.

- Keyserver pools are now handled in a smarter way.

- A new format for locally storing the public keys is now used.
  This considerable speeds up operations on large keyrings.

- Revocation certificates are now created by default.

- Card support has been updated, new readers and token types are
  supported.

- The format of the key listing has been changed to better identify
  the properties of a key.

- The gpg-agent may now be used on Windows as a Pageant replacement
  for Putty in the same way it is used for years on Unix as
  ssh-agent replacement.

- Creation of X.509 certificates has been improved.  It is now also
  possible to export them directly in PKCS#8 and PEM format for use
  on TLS servers.
