Fixed an issue where creating a development index with disableServiceQueue=false in the web.config caused exceptions to be thrown.

Fixed an issue where ContentEventIndexer loaded content with a default content cache expiration time of twelve hours. This caused content to remain in memory for longer than necessary.

Fixed an issue that left content in the page's For this page folder when the associated page was deleted, which led to clutter and potential data inconsistencies; the orphaned content was still searchable.

Fixed an issue where DefaultRequestHeaders were set when the request was made. This could lead to race condition during startup

Fixed the following authorization issue: The UI (dojo script) sent a header "Authorization" (Bearer token) to Bestbets, Editorial, and ServiceHealth controllers but those controllers only accepted Windows Authentication (which would send a WWW-Authenticate header).

Fixed an issue that may cause deadlock when the Optimizely Search & Navigation client API sent an HTTP request using the HttpClient library because the calling method waited for a response and the result was resumed on the context thread. 

Fixed an issue where settings were initiated in the client with incorrect values.

Fixed an issue where synonyms displayed a "not available" after a recent upgrade.

Fixed an issue in the indexing job that sometimes failed with an error such as

An exception occurred while fetching content.
Cannot create a command without an existing connection
or Invalid operation. The connection is closed. 

Fixed an issue where the dojo language file was missing.
