  - The downloader module has been updated to ensure it will follow HTTP redirects, and to try to workaround intermittent failures to retrieve pages from https://www.ncbi.nlm.nih.gov. This may be down to some throttling behaviour on the server, as a follow-up attempt usually succeeds. The downloader module will now make an automatic 2nd attempt to retrieve a page if the first attempt fails, with a 5 second delay between them
