***EPiServer.Find 13.5.10***

**Bug fix**

- [FIND-10951](https://world.optimizely.com/support/Bug-list/bug/FIND-10951) – Fixed an issue where newly loaded results were not bound to the proper click handler.

## August 27

***EPiServer.Find 16.3.0***

**Enhancements**

- Added the ability to backup and restore synonyms, connectors, related queries, and autocomplete from a CSV file (Import and Export lists) in the Optimizely Search & Navigation user interface.
- Added the ability to delete a document from the index in the Explore user interface so it does not appear in the search results.
- Added the asynchronous APIs versions to process requests without blocking
- Added the ability to control the `HttpClient` request timeout, `.SetTimeout(10)` for example, specifically for all requests *other* than potentiality heavy write operations (such as `bulk`, `index`, `mapping`, `delete_by_query`).
- Made `StaticallyCacheFor(10min)` the default for `GetResult()`.

**Bug fixes**

- [FIND-10951](https://world.optimizely.com/support/Bug-list/bug/FIND-10951) – Fixed an issue where newly loaded results were not bound to the proper click handler.
- [FIND-11790](https://world.optimizely.com/support/Bug-list/bug/FIND-11790) – Increased the number of document type total for the Find UI index explorer, which could only handle 100 before.
- [FIND-12648](https://world.optimizely.com/support/Bug-list/bug/FIND-12648) – Fixed an issue in `CmsRunTimeCacheAdapter` that did not apply cache's `ChangeToken`.
- [FIND-12435](https://world.optimizely.com/support/Bug-list/bug/FIND-12435) – Fixed an issue where configuring the serializer via `IClient.Conventions.CustomizeSerializer` occasionally failed to apply the specified settings. This issue arose when conflicting configurations were encountered due to simultaneous customization in the `EPiServer.Find.Framework.FrameworkInitializationModule`. Consequently, the final serializer settings became unpredictable, depending on the execution order of these configurations.
- [FIND-12783](https://world.optimizely.com/support/Bug-list/bug/FIND-12783) – Fixed an issue `EPiServer.Find.UI.ScriptInjection` custom error page was not loading for 500 errors.
- [FIND-12769](https://world.optimizely.com/support/Bug-list/bug/FIND-12769) – Fixed an issue that occurred when you performed a search (without the `EPiServer.Find.Cms.AttachmentFilter` installed); the excerpt for a document was not returned if the search term was not found within the excerpt itself.

## April 2

***EPiServer.Find 16.2.0***

**Bug fixes**

- [FIND-12436](https://world.optimizely.com/support/Bug-list/bug/FIND-12436) – Fixed an issue where `ContentEventIndexer` loaded content with a default content cache expiration time of 12 hours. This caused content to remain in memory for longer than necessary.
- [FIND-12325](https://world.optimizely.com/support/Bug-list/bug/FIND-12325) – Fixed an issue where the `MultiUnifiedSearch` did not filter documents by published language.
- [FIND-9583](https://world.optimizely.com/support/Bug-list/bug/FIND-9583) – Fixed an issue where the `CurrentlyPublished` method in `EPiServer.Find.Cms.ContentSearchExtensions` was using a time filter where the time string is rounded on minutes. It now uses `AfterNow` and `BeforeNow`. This method is used in every Content Delivery API search call which means that caching  should improve.

## February 27

***EPiServer.Find 16.1.0***

**Bug fixes**

- [FIND-12313](https://world.optimizely.com/support/Bug-list/bug/FIND-12313) – Fixed an issue where `DefaultRequestHeaders` were set when the request was made. This could lead to race conditions during startup.
- [FIND-12309](https://world.optimizely.com/support/Bug-list/bug/FIND-12309) – Fixed an issue where the explorer view filter did not work.

## January 30

***EPiServer.Find 16.0.2***

**Bug fixes**

- [FIND-12149](https://world.optimizely.com/support/Bug-list/bug/FIND-12149) – 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).
- [FIND-12144](https://world.optimizely.com/support/Bug-list/bug/FIND-12144) – 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 in the context thread.
- [12048](https://world.optimizely.com/support/Bug-list/bug/FIND-12048) – Fixed an issue with `SegmentUrlChanged` that added a record to the queue with cascade==true (should be false).
