I am currently running WC version 1.6.6.
Dashboard > Updates does not detect or list version 2.x as an upgrade. It should show that an update is available.
I have tried deactivating WooCommerce and activating again. I have tried manually forcing an update with the 'Check Again' button in Dashboard > Updates. I have tried repeatedly going to the plugins admin page.
I don't want to delete the 1.6.6 version and install 2.0.2 because I don't want to lose any data. I also don't thing copying the 2.0.2 files over the 1.6.6 files will work, due to the significant changes in 2.x.
Anyone else having this problem, or have any ideas on a solution?
