[Bioperl-l] EUtilities overhaul started

[Chris Fields]

I can confirm this; however it only relates to the use of history  
with esearch and nucleotide (use of the history with other eutils  
seems to work fine); retrieving sequences via efetch is not  
affected.  If I find out anything more I'll post something on the  
mail list.
