CentOS Changelog

What's new in CentOS 6.9

• Due to size constraints of CDs, there is no longer a LiveCD. Keeping the size small enough would have required removing everything that makes a GUI desktop functional. The LiveDVD can be copied to a USB key and used if required.
• GnuTLS now supports TLS v1.2. All packages in CentOS utilizing cryptography now support TLS v1.2.
• postfix, vsftpd, rsyslog7, ipa-server, 389-ds-base, krb5-server, sssd and libvirt have improved functionality for selecting which cipher suites are allowed.
• Net::SSLeay and IO::Socket:SSL Perl modules have been improved for better TLS support.
• Support for insecure cryptographic protocols and algorithms has been dropped. This affects usage of MD5, SHA0, RC4 and DH parameters shorter than 1024 bits.
• cloud-init, a tool for configuring new cloud instances, has now been added. Please see the entry on cloud-init in the "Known issues" section below.
• pacemaker now supports alert agents, allowing more flexibility in reacting to events in the cluster.
• clufter, a tool for converting and analyzing cluster configuration files, has been rebased to version 0.59.8.
• ca-certificates has been updated to include the latest certificate authorities as provided by the Mozilla Foundation.
• A new package cpuid is now available for displaying information about the CPUs in the system.
• Setting NO_DHCP_HOSTNAME in /etc/sysconfig/network to true will prevent network initialization scripts from changing the hostname.

• A new smartPQI driver for Microsemi storage adapters is now available.
• mpt3sas and megaraid_sas storage drivers have been updated to support more devices.
