Yes, it's kept up to date. For any annotation package, there is the SQLite database that actually contains all the data, and then a thin package wrapper that allows people to query the database without having to know any SQL. This particular package is generated in collaboration between Willem Ligtenberg and Bioconductor. He generates some of the tables in the SQLite DB, then sends it to us, and we put in the rest. So that part gets updated every six months, and it's really the only important part.
To generate the package we then take the package from the last release, dump out the database, and put the new one in there, increment the version number, and build. So everything except the SQLite database is old, having been originally generated back in 2010. This includes the part you show above - if you go to that website, there isn't even a sql.gz file in there! Probably hasn't been one for years.
Probably more than you wanted to know, but hope it helps.
