   - Got rid of `removeImageForKey:` and `removeImageForKey:fromDisk:` from `SDImageCache` that looked sync but were async. Left only the 2 async ones
   - Removed `UIImageView` `sd_cancelCurrentHighlightedImageLoad`
 - Added `sd_` prefix to the activity indicator related methods (`setShowActivityIndicatorView:`, `setIndicatorStyle:`, `showActivityIndicatorView`, `addActivityIndicator`, `removeActivityIndicator`) #1640
+- Use `dispatch_main_async_safe` for all the completion blocks on the main queue (used to be `dispatch_sync`) - avoiding locks.
+- Removed `dispatch_main_sync_safe` as it can be mistakenly used
+- Add `url` as param to progress block `SDWebImageDownloaderProgressBlock` - #984
 
 #### Features:
 
@@ -76,13 +81,24 @@
 - Created `SDWebImageDownloaderOperationInterface` to describe the behavior of a downloader operation. Any custom operation must conform to this protocol df3b6a5
 - Refactored all the duplicate code from our `WebCache` categories into a `UIView` `WebCache` category. All the other categories will make calls to this one. Customization of setting the image is done via the `setImageBlock` and the `operationKey` e1840c3
 - Due to the change above, the activity indicator can now be added to `UIButton`, `MKAnnotationView`, `UIImageView`
+- Animated WebP support #1438
+- The shared objects (not really singletons) should allow subclassing, therefore the return type of the shared resource method should be `instancetype` and not a fixed type - c57cf7e
+- Allow to specify `NSURLSessionConfiguration` for `SDWebImageDownloader` #1654
+- Add `url` as param to progress block `SDWebImageDownloaderProgressBlock` - #984
 
 #### Fixes:
 
 - Fix multiple requests for same image and then canceling one #883 + 8a78586
 - Fixed #1444 and the master build thanks to [@kenmaz](https://github.com/kenmaz/SDWebImage/commit/5034c334be50765dfe4e97c48bcb74ef64175188)
 - Fixed an issue with the `SDWebImageDownloaderOperation` : `cancelInternal` was not called because of the old mechanism rellying on the `thread` property - probably because that thread did not have a runloop. Removed that and now cancelInternal is called as expected f4bdae6
-
+- Replaced #781 on replacing dispatch_sync with dispatch_async for the main queue 062e50a f7e8246 c77adf4 fdb8b2c 265ace4 0c47bc3. Check for main queue instead of main thread.
+- Fixed #1619 iOS 10 crash (`setObjectForKey: object cannot be nil`) - #1676 7940577
+- Fixed #1326 #1424 (`Carthage bitcode issue`) - #1593
+- Fixed #1639 via #1657 (`Add support for downloading images behind redirect`)
+- Replaced #1537 via 9cd6779 - fixed a potential retain cycle
+- Updated `dispatch_main_async_safe` macro in order to avoid redefinition when included as Pod
+- Fixed #1089 by updating the docs on the calling queue for the `progressBlock` (background queue)
+- Fixed a compilation issue on `FLAnimatedImageView+WebCache` - #1687
