It seems like version 2.5.2 was released on December 10, but the version was not incremented in the spec file and the GNUmakefile: $ git describe --tags | awk -F "v" '{print $2}' 2.5.2 $ grep base_version amazon-ec2-net-utils.spec %define base_version 2.5.1 $ grep version GNUmakefile version=2.5.1 This busts our automated build of the rpm.
