• Add --generator option for eunit, which lets you run individual test cases
• implement mib_first_files support in rebar_compiler_mib
• Support ignoring entire modules in xref results
• Add a --fail_fast switch to common test which aborts the whole test run as soon as one of them fails -- this feature is experimental

• update relx to 3.28.0
• Update hex_core and add mirror_of repo config
• bump erlware_commons to 1.3.1
• re-expose download/3 for backwards compatibility in git deps-related plugins
