The new Ensembl marts for release 105 are now live on www.ensembl.org. If you are using biomaRt, you can change your host to access our most recent data:
ensemblmart105 <- useEnsembl(biomart=“ensembl")
PS: if you want force one previous version you can use: ensembl_[VERSION] <- useEnsembl(biomart = "ensembl", version = [VERSION])
On behalf of Ensembl Team. Thanks.
