The import format is exactly the same. The fixes were mostly with the database they got copied into failing because of one of a couple errors. The UI was also simplified so that the imported pois shows up on the main poin page rather then the custom type selection module.
Alot of online poi formats just seems to have latitude, longitude, name, and description. StreetDeck currently requires the description to be broken down into a complete address so they are probably not going to import correctly. We will probably support a a simpler format in the future, but right now its not on the road map.
As long as your file has a latitude and longitude in the 7th and 8th fields, the import should work.
