rpm-4.0.2 for all Red Hat platforms and releases.

A common version of rpm for all Red Hat distributions is being released.
This version of rpm understands legacy version 3 packaging used in Red
Hat 6.x/5.x distributions as well as version 4 packaging used in Red Hat
7.x.
In addition, rpm-4.0.2 has support for both the legacy db1 format used in
Red Hat 6.x/5.x databases as well as support for the db3 format database
used in Red Hat 7.x

Several potential problems

1) Red Hat 6.x/5.x users will need to install the db3 packages from
RHEA-2001:015-09.

2) Red Hat 5.x users should note that the default compiler flags in rpm
have changed, and are not compatible with the gcc originally shipped
with Red Hat 5.2. Use egcs as a compiler instead.

3) Red Hat 6.x/5.x users should convert from db1 to db3 format dtabases at
your earliest convience. This can be done by running, as root, the
command
rpm --rebuilddb
Support for legacy db1 format rpm databases will be removed in the next
release of rpm.

4) All platforms: If you chose to install rpm-4.0.2, and then go back to a
previous version of rpm, then you will experience segfaults due to an
incompatible change in headers in the database. The problem is in
legacy versions of rpm going back to rpm-3.0, and is both caused and
fixed by rpm-4.0.2. This incompatibility also applies to any/all
applications that are statically linked against rpm libraries which
should either be upgraded or recompiled to use rpm-4.0.2 libraries.
Applications that use shared libraries should not be affected by this
problem.

5) All platforms: rpm-4.0.2 will fail to install if you have both db1 and
db3 rpm databases in /var/lib/rpm. If the packages do not install,
please check the directory /var/lib/rpm for the files "packages.rpm"
(the db1 format headers) and "Packages" (the db3 format headers)
and rename/remove the older or smaller of the two files in order to
upgrade.

To update all RPMs for your particular architecture, run:

rpm -Fvh <filenames>

where <filenames> is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directly *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
