func-e 1.1.4 is a maintenance release built with Go 1.19.
Note: Recent versions of Envoy no longer run on the default build of CentOS 8, and attempts will result in the following error /lib64/libm.so.6: version 'GLIBC_2.29' not found. This is not an issue func-e can resolve, so please contact Envoy with platform support concerns.
