[undertow-dev] 1.2.9.Final tag missing in git repo

Hi, I'm trying to build WildFly 9.0.1.Final from source. WildFly 9.0.1.Final seems to depend on WildFly core 1.0.1.Final, which on its turn depends on Undertow 1.2.9.Final. However, there's no tag 1.2.9.Final at https://github.com/undertow-io/undertow I see a 1.2.8.Final and a 1.2.10.Final Am I missing something? Kind regards, Arjan Tijms
