Upgrading 1.64 to Joomla 1.71 - No Package

Question:
I know how to do the updates but I CAN NOT find the update for v1.64 to 1.70 or 1.71

There does NOT seem to be a package for upgrading from 1.61 1.62 1.63 1.64 and I have not found any documentation

This is what I find here on the Joomla Files Page: http://joomlacode.org/gf/project/joomla/frs/?action=index

I can upgrade in 3 steps:

1.60 to 1.66 - Joomla_1.6.0_to_1.6.6-Stable-Patch_Package.zip
1.65.to 1.70 - Joomla_1.6.5_to_1.7.0_Package.zip
1.70 to 1.71 - Joomla_1.7.0_to_1.7.1-Stable-Patch_Package.zip

Is this the only way - and will this work???
