[ensembl-dev] database model and API versions

Hi Duarte,

The archive 75 website is still based on the release 75 API.

For the dedicated GRCh37 website though, we have used a data freeze from 
release 75 and have since been updating the website and underlying 
databases along with the main release.
The GRCh37 databases are available on our main MySQL server on port 3337 
(instead of the default 3306 which will give you access to GRCh38 databases)

Hope that helps,
