If you are modifying Go code, please make sure it's as idiomatic as possible and that it satisfies at least gofmt, golint and go vet. Only the last stable release will be supported. There's a golangci-lint configuration file .golangci.yml in case you want to ensure your code is idiomatic.
Docker images changes should aim to keep them small but simple and avoid adding unneeded layers. Only the last stable version of Docker will be supported and images will assume buildkit is enabled.
Please, remember that this is a side project and reviewing proposals or PRs and fixing bugs might take some time.
