search_api 8.x-1.7

This is release 1.7 of the Search API module, containing several bug fixes and new features.

One noteworthy change is that #2922525: Index items only at end of page request changed the “Index items immediately” option to delay indexing until the end of the page request (instead of index right away when the change occurs). This is in line with the functionality in Drupal 7 and is expected to resolve several edge case problems that occurred previously as well as improve performance.
However, it is possible that this change could also lead to problems in (other) edge cases, so please (if you have “Index items immediately” enabled for one or more search indexes) make sure to thoroughly test this new module version on your site and report any problems you notice!

Also, if you are using node access and the "Content access" processor on your site, your feedback (or patch testing) could be very helpful in #2948707: ContentAccess processor fails to account for all grant records to ensure we don't break any existing functionality.
