Hi Michael,

Most of this information is available via the meta table.

The API will allow you to fetch this information with the following queries:
my $meta_container = $registry->get_adaptor('human', 'core', 
my $api_version = $meta_container->get_schema_version();
my $genebuild_version = $meta_container->get_genebuild();
my $coord_system_adaptor = $registry->get_adaptor('human', 'core', 
my $genome_version = $coord_system_adaptor->fetch_top_level();

It is however not possible to retrieve information about previous builds 
from the current database.
To do this, you would need to check the genebuild_version, which 
indicates when the genebuild was last updated.
Based on the data, find the archive prior to that date.

It is also possible to retrieve this information from the REST API.

will return the current Ensembl version

will return basic information about the current genebuild and assembly 
for a given species.
