search_api_attachments 8.x-1.0-alpha5

This is D8 alpha5 release of search_api_attachments module.

This module depends on search_api that is usable but not yet stable, and so, it is not recommended to use this version in production.

Especially, note that there will be no data update path for this module's configuration while the module is in Alpha status!

This release fixes some bugs and adds some features.
