Subject: PGP 2.5 Beta Release Over, PGP 2.6 to be release next week
Date: 16 May 1994 18:13:17 GMT
Organization: Massachusetts Institute of Technology
-----BEGIN PGP SIGNED MESSAGE-----
The beta version of PGP 2.5 is now being removed from MIT file servers.
In about a week, MIT will begin distribution of a new release numbered
PGP 2.6. PGP 2.6 will incorporate a new version of RSAREF, scheduled for
release by RSA Data Security next week, and will also correct bugs that
were reported in PGP 2.5.
In order to fully protect RSADSI's intellectual property rights in
public-key technology, PGP 2.6 will be designed so that the messages it
creates after September 1, 1994 will be unreadable by earlier versions
of PGP that infringe patents licensed exclusively to Public Key Partners
by MIT and Stanford University. PGP 2.6 will continue to be able to read
messages generated by those earlier versions.
MIT's intent is to discourage continued use of the earlier infringing
software, and to give people adequate time to upgrade. As part of the
release process, MIT has commissioned an independent legal review of the
intellectual property issues surrounding earlier releases of PGP and PGP
keyservers. This review determined that PGP 2.3 infringes a patent
licensed by MIT to RSADSI, and that keyservers that primarily accept 2.3
keys are mostly likely contributing to this infringement. For that
reason, MIT encourages all non-commercial users in the U.S. to upgrade
to PGP 2.6, and all keyserver operators to no longer accept keys that
are identified as being produced by PGP 2.3.
