-Unpacking the Source Distribution
----------------------------------
+Copyright and Other Notices
+---------------------------
-The source distribution of Kerberos 5 comes in a gzipped tarfile,
-krb5-1.5.tar.gz. Instructions on how to extract the entire
-distribution follow.
+Copyright (C) 1985-2010 by the Massachusetts Institute of Technology
+and its contributors. All rights reserved.
-If you have the GNU tar program and gzip installed, you can simply do:
-
- gtar zxpf krb5-1.5.tar.gz
-
-If you don't have GNU tar, you will need to get the FSF gzip
-distribution and use gzcat:
-
- gzcat krb5-1.5.tar.gz | tar xpf -
-
-Both of these methods will extract the sources into krb5-1.5/src and
-the documentation into krb5-1.5/doc.
+Please see the file named NOTICE for additional notices.

+The Data Encryption Standard (DES) is widely recognized as weak. The
+krb5-1.7 release contains measures to encourage sites to migrate away
+from using single-DES cryptosystems. Among these is a configuration
+variable that enables "weak" enctypes, which defaults to "false"
+beginning with krb5-1.8.
+
+Major changes in 1.9
+--------------------
+
+Code quality:
+
+* Fix MITKRB5-SA-2010-007 checksum vulnerabilities (CVE-2010-1324 and others)
+* Python-based testing framework
+* DAL cleanup
+
+Developer experience:
+
+* NSS crypto back end
+* PRNG modularity
+* Fortuna-like PRNG
+
+Performance:
+
+* Account lockout performance improvements -- allow disabling of some
+ account lockout functionality to reduce the number of write
+ operations to the database during authentication
+
+Administrator experience:
+
+* Trace logging -- for easier diagnosis of configuration problems
+
+* Support for purging old keys (e.g. from "cpw -randkey -keepold")
+
+* Plugin interface for password sync -- based on proposed patches by
+ Russ Allbery that support his krb5-sync package
+
+* Plugin interface for password quality checks -- enables pluggable
+ password quality checks similar to Russ Allbery's krb5-strength
+ package
+
+* Configuration file validator
+
+* KDC support for SecurID preauthentication -- This is the old SAM-2
+ protocol, implemented to support existing deployments, not the
+ in-progress FAST-OTP work.
+
+Protocol evolution:
+
+* IAKERB -- a mechanism for tunneling Kerberos KDC transactions over
+ GSS-API, enabling clients to authenticate to services even when the
+ clients cannot directly reach the KDC that serves the services.
+
+* Camellia encryption (experimental; disabled by default)
+
