[ensembl-dev] versioning of ensembl & biomart

[rhoda at ebi.ac.uk]

Hi Vincent
Unfortunately, someone has been hitting our mart servers with a lot of
queries over the past few days and we are trying to resolve the
connectivity issue. Can you try your query again today and let me know if
you can retrieve your results? You will need to keep an eye on
www.biomart.org to determine when this is updated with the new release 65
databases or perhaps you could subscribe to the biomart users mailing list
(users at biomart.org). The BioMart team are generally quite quick to update
these databases once we have added them to the public mysql server and
they usually let me know when they have been added to the biomart central
portal. I then email the biomart users mailing list and bioconductor
mailing list to let everyone know about the fixes and additions in the new
marts. I hope that helps.
Regards
Rhoda
