Hi all,

Just FYI, the following was also changed in this week's Entrez
update to EFetch 2.0 (see forwarded email below).

This was breaking some Biopython scripts - depending on how
they passed in the id parameters. It turns out we relied on the
undocumented and now withdrawn form in one of our examples,
so some users had copied this style. Biopython 1.59 will solve

I know BioJava is looking at the more publicised changes to
retmode - I don't know if BioPerl or BioRuby was affected.

The most recent NCBI E-Utilities update includes a more stringent
check for correct URL parameters.

EFetch URLs with multiple IDs must be entered as: id=1,2,3

EFetch no longer accepts invalid URL parameters, e.g., id=1&id=2&id=3

Please see the online E-Utilities help for additional information:
