1.1       root        1: Changes to PGP 2.6:
                      2: 
                      3: This version of PGP uses a version of RSAREF provided to MIT by RSA Data
                      4: Security for use in PGP. This version is legal within the U.S.  See the
                      5: enclosed RSAREF license for full details. Basically this is a
                      6: non-commercial release. If you want to use it in a commercial or
                      7: governmental setting, talk to ViaCrypt (2014 West Peoria Avenue,
                      8: Phoenix, Arizona 85029, +1 602 944-0773).
                      9: 
                     10: While PGP version 2.5 used RSAREF version 2.0, PGP 2.6 uses RSAREF
                     11: version 1.  This change was made in consultation with RSA Data
                     12: Security, which is currently revising its version 2.0 distribution.
                     13: The version of RSAREF included with this distribution is RSAREF
                     14: version 1, not version 2.0.
                     15: 
                     16: PGP 2.6 will read messages, signatures and keys created with versions of
                     17: PGP post 2.2. (i.e., 2.3, 2.3a, 2.4 and 2.5). However after 9/1/94 Version
                     18: 2.6 will create messages which contain a version number of "3" in signatues,
                     19: messages and keys (see pgformat.doc for details). PGP2.6 will be able to
                     20: read these signatures, messages and keys, but prior versions will not.
                     21: 
                     22: Versions prior to 2.6 would not permit a new signature to be added to a key
                     23: if there was an already existing signature from the same signer. Starting
                     24: with version 2.6 newer signatures will override older ones *as long as the
                     25: newer signature verifies*. This change is important because many keys have
                     26: signatures on them that were created by PGP version 2.2 or earlier. These
                     27: signatures can not be verified by PGP 2.5 or higher. Owners of keys with
                     28: these obsolete signatures should attempt to gather new signatures and
                     29: add them to their key.
                     30: 
                     31: Significant changes were also made for version 2.5. Because version 2.6 is
                     32: coming out very soon after 2.5 (which was only really a beta test version)
                     33: readers are encouraged to read the file "newfor25.doc" as well as this file.
