We are adopting a new versioning scheme.
o Each feature release will have a new major number.
o The minor will be a patch level. A value of 0 is
reserved for release candidates. A value of 99 is
reserved for development.
o Stable releases will not have a micro number (always 0).
o Micro numbers will be incremented in release candidates
and development as needed.
For example, the release candidates for 7.1 were 7.0.1, 7.0.2 and
All bug fixes will then be 7.2, 7.3, etc.
New development for Heimdal 8 will be 7.99.1, 7.99.2, 7.99.3, etc.
When the next feature release is issued its version number will
start with 8.0.1 as the first release candidate and the first
release will be 8.1.
Major changes in Heimdal 7:
We have a lot of major improvements since our last official
o hcrypto is now thread safe on all platforms and
as much as possible hcrypto now uses the operating
system's preferred crypto implementation ensuring
that optimized hardware assisted implementations of
AES-NI are used.
o RFC 6113 Generalized Framework for Kerberos
o Hierarchical capath support
o iprop has been revamped to fix a number of race
conditions that could lead to inconsistent replication.
o The KDC process now uses a multi-process model improving
resiliency and performance.
o AES Encryption with HMAC-SHA2 for Kerberos 5
o Moved kadmin and ktutil to /usr/bin
o Stricter fcache checks (see fcache_strict_checking krb5.conf setting)
o Removed legacy applications: ftp, kx, login, popper, push, rcp, rsh,
