PGP と GnuPG

今回のリリースでは、 1.4.7 における不具合の修正や機能の改善・追加などが行われています。

What's New
===========
 
    * Changed the license to GPLv3.
 
    * Improved detection of keyrings specified multiple times.
 
    * Changes to better cope with broken keyservers.
 
    * Minor bug fixes.
 
    * The new OpenPGP standard is now complete, and has been published
      as RFC-4880.  The GnuPG --openpgp mode (note this is not the
      default) has been updated to match the new standard.  The
      --rfc2440 option can be used to return to the older RFC-2440
      behavior.  The main differences between the two are
      "--enable-dsa2 --no-rfc2440-text --escape-from-lines
      --require-cross-certification".
 
    * By default (i.e. --gnupg mode), --require-cross-certification is
      now on.  --rfc2440-text and --force-v3-sigs are now off.
 
    * Allow encryption using legacy Elgamal sign+encrypt keys if
      option --rfc2440 is used.
 
    * Fixed the auto creation of the key stub for smartcards.  
 
    * Fixed a rare bug in decryption using the OpenPGP card.
 
    * Fix RFC-4880 typo in the SHA-224 hash prefix.  Old SHA-224
      signatures will continue to work.
