==== Bug fixes

* Previously, when you injected proxy environment variables in a build container, they replaced the default proxy settings and caused build failures due to external binary compatibility issues. Also, if no default variable was set, a null value was replaced, which caused applications to break. With this release, a check for a null proxy environment variable is added to the process and the injected proxy variables are added only if they are defined in the default variables and if the variable is not equal to a null value. (link:https://issues.redhat.com/browse/OCPBUGS-57171[OCPBUGS-57171])
