has been updated. The main focus of these updates is definitely the desktop version. The spell checker has been updated with new languages (Korean, Tamil, and Albanian) as well as refreshed dictionaries. Personal dictionaries will also be synced between devices.
On the topic of spell checking, if you haven't tried "Ask Google for suggestions" then I do recommend trying it out. By enabling this the words will be checked by the same servers that do corrections on Google Searches for grammar, homonym, and contextual errors. It really does work well in my opinion. To enable this, next time a red line appears under text right click on it as usual and click on "Ask Google for suggestions."
