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. 详细列表请看：https://gnupg.org/faq/whats-new-in-2.1.html GnuPG 2.1.0 "modern" 发布，邮件加密工具下载地址
