Earthly 0.3.6 Released

Earthly's recent updates include the introduction of a --ssh flag for the RUN command, which enables access to the SSH authentication host agent via the $SSH_AUTH_SOCK socket, addressing a previous issue (#292). Other notable improvements are the ability to pass user terminal environment variables to the interactive debugger (#293) and support for in-line comments (#288). Additionally, a bug related to autocompletion when an Earthfile is invalid has been fixed (#299). These changes are part of a broader effort to simplify the building process and enhance functionality, with detailed documentation provided for the new --ssh feature.
