This is the Alpha 15 release of the Search API module's Drupal 8 version.
This release changes the configuration format of the default entity datasources (i.e., how the bundle and language settings are stored). This means manual intervention will likely be needed if you're updating to this version from Alpha 14 on a site with datasources restricted to certain bundles and/or languages.
There were no other major schema changes.
This is the second stable release of Address Field Lookup. It's been a little while since 7.x-1.0 I know but busy times and all that! This release contains a couple bug fixes and adds a suite of unit tests.
