CentOS 5.9, the open source version operating system based on Red Hat Enterprise Linux, is the successor to CentOS 5.8.
New features include:
- The UOP added native MySQL support to postfix. More information can be found here. You might consider moving from the postfix-mysql package from the centosplus repo to this package if you are using the centosplus package only for mysql support. The centosplus package also has postgresql support, so if you need that you will still need to use the centosplus package.
- java-1.7.0-openjdk (Java 7) support has been added in CentOS-5.9. java-1.6.0-openjdk (Java 6) is also still available and most things java in the distribution still use Java 6.
- ant17 (Ant 1.7.0) has been added to CentOS-5.9. The older ant (Ant 1.6.5) is also still available.
- Microsoft Hyper-V drivers have been added to allow CentOS to be more efficient as a Virtual Machine when installed on Microsoft Hyper-V server.
- A newer version of rsyslog (name rsyslog5) is included. The original rsyslog (rsyslog version 3.22) is still available and the version installed by default.
- The samba3x packages have been rebased on samba-3.6.x. This provides the smb2 protocol and a newer network print server.
