 * Added support for a sync configuration option to provide an `SSLConfiguration` with a custom function for validating the server's SSL certificate. ([#5485](https://github.com/realm/realm-js/issues/5485))
 * Improve performance of equality queries on a non-indexed mixed property by about 30%. ([realm/realm-core#6506](https://github.com/realm/realm-core/pull/6506))
 * Improve performance of rolling back write transactions after making changes.  ([realm/realm-core#6513](https://github.com/realm/realm-core/pull/6513))
+* Extended `PropertySchema.indexed` with the `full-text` option, that allows to create an index for full-text search queries.  ([#5755](https://github.com/realm/realm-js/issues/5755))
 
 ### Fixed
 * Fix a stack overflow crash when using the query parser with long chains of AND/OR conditions. ([realm/realm-core#6428](https://github.com/realm/realm-core/pull/6428), since v10.11.0)
