Geeklog 1.8.1 does not introduce any changes in the language files (other than some updated or new translations), in the theme, or in the database. So upgrades from Geeklog 1.8.0 should be pretty straightforward.
Please help us test this release candidate so that we can release the final version soon. Thanks.
