$tcsh_posix_status variables, which define the tcsh behavior in case of an error of any pipelined command. This update brings the
tcsh functionality closer to the Red Hat Enterprise Linux 7
tcsh version. Note that these two variables have opposite logical meanings. For more information, see the tcsh(1) manual page. (BZ#1256653)
OpenJDK 8 now supports ECC
With this update, OpenJDK 8 supports Elliptic Curve Cryptography (ECC) and the associated ciphers for TLS connections. ECC is in most cases preferable to older cryptographic solutions for making secure network connections.
Additionally, the java-1.8.0 package priority has been expanded to 7 digits. (BZ#1208307
RC4 is now disabled by default in OpenJDK 6 and OpenJDK 7
Earlier OpenJDK packages allowed the RC4 cryptographic algorithm to be used when making secure connections using Transport Layer Security (TLS). This algorithm is no longer secure, and so has been disabled in this release. To retain its use, it is necessary to revert to the earlier setting of the
SSLv3, DH keySize < 768. This can be done permanently in the
<java.home>/jre/lib/security/java.security file or by adding the following line:
jdk.tls.disabledAlgorithms=SSLv3, DH keySize < 768
to a new text file and passing the location of that file to Java on the command line using the argument
-Djava.security.properties=<path to file>. (BZ#1217131)

An export to Zabbix tool has also been added via zbxpcp(3). The pcp-atop tool has received a full rewrite, including a new NFS feature set. PCP's Performance Metrics Web Daemon (pmwebd) has received improvements, such as opening directories-as-archives for graphite, as well as adding support for the PCP pmStore(3) protocols. sar2pcp(1) has also been updated to include support for sysstat 11.0.1 commands.

To preserve compatibility with Red Hat Enterprise Linux 6.7, openmpi-1.8 is still available. Its package name is openmpi-1.8 and it keeps the environment module name ( openmpi-x86_64 on the x86_64 architecture) it had in Red Hat Enterprise Linux 6.7. (BZ#1130442)
Changes in Open MPI distribution
Open MPI is an open source Message Passing Interface implementation. The compat-openmpi package, which provides earlier versions of Open MPI for backward compatibility with previous minor releases of Red Hat Enterprise Linux 6, has been split into several subpackages based on the Open MPI version.
The names of the subpackages (and their respective environment module names on the x86_64 architecture) are:
openmpi-1.5.3 (compat-openmpi-x86_64, aliased as openmpi-1.5.3-x86_64)
openmpi-1.5.3-psm (compat-openmpi-psm-x86_64, aliased as openmpi-1.5.3-psm-x86_64)
openmpi-1.8 (openmpi-x86_64, aliased as openmpi-1.8-x86_64)
yum install openmpi
command in Red Hat Enterprise Linux 6.8 installs the openmpi-1.8
package for maximum compatibility with Red Hat Enterprise Linux 6.7. A later version of Open MPI is available in the openmpi-1.10
Omping is now fully supported
Open Multicast Ping (Omping) is a tool to test the IP multicast functionality, primarily in the local network. This utility allows users to test IP multicast functionality and assists in the diagnosing whether a problem is in the network configuration or there is a bug.
