This is primarily a stabilization release although a few new features have been added.
- PageCache now has a MaxCachedPages property, which can be used to configure the maximum number of pages that can be cached. The default is 1000. Pages are removed from the cache in least-used order.
- Page data is buffered in-memory before being read or written. This is actually more performant, so the persisted full text index users should see a performance boost.
- PersistedFullTextIndex is now thread-safe and can now be read by multiple readers. (The single-writer limitation is still in place, as with the standard updatable full text index, however.)
- A race condition could occur when indexing items in the persisted full text index in quick succession. This lead to data corruption in the backing file store.
