[BioC] Announcement: biomaRt attribute/filter name changes involving gene symbols

[Steffen]

Dear biomaRt users,

Tomorrow the Ensembl BioMart database will fix it's current Ensembl 47 
release with the following attribute/filter name changes involving gene 
symbols.

* For the hsapiens_gene_ensembl (human) dataset you'll need hgnc_symbol 
as attribute and filter name to use/retrieve gene symbols.
* For the mmusculus_ensembl_gene (mouse) dataset you'll need the 
mgi_symbol as attribute and filter name (this was markersymbol in 
previous versions).
* For the drerio_gene_ensembl (zebrafish) dataset you'll need 
zfin_symbol to use/retrieve gene symbols.

Note: These names for attributes and filters that refer to gene symbols 
have been subject to changes in the recent months but now Ensembl has 
promised to keep them stable from now.

Cheers,
Steffen
