Hi Andy


Thank you very much for the 'heads-up'

Just a quick question in order to double check: Ensembl 75 will still 
require the old BioPerl version (i.e. BioPerl 1.2.3) ?

Regards, Hans

This was in part motivated by the improved runtime and memory consumption seen in later versions of Perl especially in the 5.14 development tree. We were also motivated by some new language constructs only available with later versions of Perl (smart match operators, non-destructive regular expressions, defined OR operators).
