Looks like Relevanssi is compatible with WordPress 4.7, but one problem has been found so far: admin dashboard search for pages doesn’t work with Relevanssi. Other post types seem to work just fine. I wasn’t able to fix the problem, so this version circumvents it by disabling Relevanssi in the admin page search.

This version also fixes admin menu searching, which was broken with Relevanssi even before 4.7. There’s also a new feature that’ll make highlighting words with accented characters better. Pinning will also support multi-word search terms.

• Relevanssi broke the WP admin menu search when admin searches were enabled.
• Pinning now supports multi-word search terms.
• Relevanssi broke the admin page search under WP 4.7. Relevanssi is now disabled in admin page searches.
• The way accented characters are handled in highlighting is improved. A new filter, relevanssi_accents_replacement_arrays, can be used to adjust the accent replacement.

Get the new version from auto update or from the Download page.
