acu92820 - Release4.8
acu81699 fixed download retriver attempting to override repo_dir declared in base class because there are other paths that call Base.repo_dir
fixed issue with curl output (in case of error) raising exception because @output buffer was an array not a safe buffer
not sure how this was working for metadata_scraper unless it used same repo_dir by coincidence
v3.2.2
