lib/str.sh gains firstword, lastword, or, patsubst, filter, filter_out, addprefix, addsuffix and jwt: what the catalogue .mk files are written in. The make JWT macro split on the commas of its payload; this one does not. lib/context.sh registers COMPOSE_PROJECT_NAME, APP, DOCKER_NETWORK_* and the rest as lazy defaults, so a converted .mk keeps reading them as it did. Hooks also load a directory-level _stack.env and _stack.sh, for the .mk files of the catalogue that hold settings for several stacks at once.
