Omeka still version 1.5.3 - upgrade?

When is DreamHost going to upgrade the version of Omeka it offers for one click install? Omeka 2.0 came out in 2013, but DreamHost is still only offering 1.5.3. Omeka developers noted that they sent the new version to DreamHost two years ago on one of the Omeka forums. Does anyone know when DreamHost is going to upgrade? If they have no plans to upgrade, they should remove Omeka from their one click install.
