This is the first Beta release of the Search API Location project. Compared to the previous development versions, there were huge changes, as detailed in. If you were using a development version, you will likely have to re-configure your search set-up.
The good news, however, is that no more patching is necessary! The Search API Solr module already supports location searches out-of-the-box, no more hacking needed. The old processor is now also unnecessary and was therefore removed.
The map widget for filtering Views by location was moved to the new "Search API Location Map" sub-module. Please use that if you want the old map functionality back. Two other sub-modules, "Search API location pages" and "Search API location views" take care of providing location searches for search pages and search views, respectively. Without those, your searches won't have any location-search capabilities.
