Hi Miika and BioC list,

I've added bosTau4 (Cow) to our list of supported genomes.

Some important changes since bosTau3:
- all chromosome sequences have changed: they are about
   10% longer in bosTau4,
- there is now a chrM sequence,
- UCSC also provides the upstream sequences for bosTau4 so
   I've included them in BSgenome.Btaurus.UCSC.bosTau4
- I've included the full set of masks (assembly gaps, inter-contig
   ambiguities, RepeatMasker and Tandem Repeats Finder).

I've also made a new version of BSgenome.Btaurus.UCSC.bosTau3
(version 1.3.12) that includes the full set of masks (version
1.3.11 only had the masks of assembly gaps and inter-contig

Those 2 new packages (BSgenome.Btaurus.UCSC.bosTau4 and
BSgenome.Btaurus.UCSC.bosTau4 1.3.12) are only available
in the current release (BioC 2.3) and as source packages
for now (the binary versions for Windows and Mac will follow

As always, check what genomes are available for your platform with:

   > library(BSgenome)
   > available.genomes()

or use the 'type' argument to check for a specific type of
