Yes it's finally here! It's been tested to update the game from the base
2012 version all the way up to patch 6.18. This also works across all
expansions, and the previous boot patches that were supported before.
However, the patcher dialog is in need of an update, as patching happens
on the same thread so the entire application freezes.
This matches behavior in the official retail launcher, if Astra detects
a mismatch between installed expansions and the expansions reported by
your service account, Astra will now report them as missing and in need
of patching.
