This update includes the following enhancements:

 - Addition of the exec-shield and PIE (Position Independent 
    Executable) features, which provide protection against stack, 
    buffer or function pointer overflows, and against other types 
    of security exploits that rely on overwriting data structures in 
    memory.

 - Addition of NX support for 32-bit x86 architectures in addition to 
    AMD64 and Intel(r) EM64T.  NX technology restricts execution of 
    program code in specific areas of memory such as the stack or 
    the heap, preventing many common buffer overflow security 
    vulnerabilities.

 - Upgrade of autofs to version 4, which improves NFS automount 
    robustness and adds features including browsable mounts, 
    replicated servers, executable maps, and multi-mounts.
    Refer to the Update 3 release notes for more details.

 - Addition of support for local disk kernel crash dump targets in 
    addition to network targets, via the new diskdumputils package.  
    Currently, only x86 and Itanium2 platforms with SCSI subsystems 
    that use either the aic7xxx, aic79xx, or mptfusion drivers are 
    supported.

 - Support for additional IBM POWER5 platforms.

 - Addition of installer support for device driver update CDs.

 - Addition of the Exchange Connector for Evolution, which enables
    the use of the Evolution groupware client with Microsoft 
    Exchange mail servers.

 - Update of the IA-32 Execution Layer, which allows emulation 
    of 32-bit x86 binaries on 64-bit Itanium2 systems.

 - Additional 32-bit runtime library support for 64-bit platforms.

 - Driver updates including Adaptec RAID (aacraid), LSI Logic 
    RAID (megaraid), IBM ServeRAID (ips), LSI Logic MPT Fusion (mpt*),
    Compaq SA53xx Controllers (cciss), QLogic Fibre Channel (qla2xxx),
    Intel PRO/1000 (e1000), Intel PRO/100 (e100), Broadcom 
    Tigon3 (tg3), and Serial ATA (libata).  Refer to the Update 3 
    release notes for more details on driver updates.

 - Driver additions including Emulex Fibre Channel (lpfc) and 
    Promise SATA SX8 (carmel).

 - Support for many additional Serial ATA (SATA) adapters.

 - Availability of a full set of updated installable CD ISO 
    images via Red Hat Network, with OS package updates and 
    install-time support for new hardware.

 - Security updates, bug fixes, and feature enhancements to
    numerous system packages.
