  • Fix "--delete" flag would not actually delete the index

  • User's must have '[ESE] Autocomplete' permission in a global context, while '[ESE] Autocomplete' can be revoked per-forum.

  • Requires re-indexing of resources & AMS Articles to enable this!

  If search result suggestion validation is enabled, a search with no results will redirect to the suggested search term with the most results.

• Fix "Cannot access offset of type string on string" on some member thread lists

Elasticsearch currently contains a vulnerability which can allow remote code execution or leaking server IP.

It is strongly recommended to upgrade to Elasticsearch 6.3+ and apply the documented migration.
