Original Message: We have added yum 2.4.3 updates for CentOS 3 and 4 to the CentOS testing repository. These packages introduce the following changes: * CentOS 4: yum now requires the yum-metadata-parser package. This is a backport of the yum C metadata parser, and provides an significant performance increase over the Python metadata parser. * CentOS 3: this is the first release of yum 2.4 for CentOS 3, and we plan to provide this as an optional upgrade through the CentOSPlus repository. We have added code to yum 2.4 for default kernel handling (as setting the default kernel after kernel updates was handled by yum 2.0). Additionally, the package also requires the yum C metadata parser. Please test these RPMs, and provide feedback. We are especially interested in stress testing of the new components (default kernel handling on CentOS 3, and the C metadata parser on CentOS 3 and 4). ======================================================================== The new yum loaded easily and properly on C4. Am very impressed with the TREMENDOUS increase in speed!
