Is there an up to date Spanish Dictionary?

I have downloaded the Spanish Dictionary from here: Extension Manager shows the extension but it does not appear in the menu of available languages.

I wonder if it is incompatible with the current version of LibreOffice. The last update was in 2011 and mentions only versions 33., 3.4, 3.5.

Any advice would be welcome.

Better download the Spanish dictionaries from the project’s github repo:
