+### New in 0.11.0 (released 2015/05/10)
+* New: Added overload to `IRepositoryClient.GetAllPublic` specifying a `since` parameter - #774 via @alfhenrik
+* New: Added `IGistsClient.GetAllCommits` and `IGistsClient.GetAllForks` implementations - #542 via @haagenson, #794 via @shiftkey
+* New: Added `IRepositoryContentsClient.GetArchiveLink` for getting archived code - #765 via @alfhenrik 
+* Fixed: `PullRequestFile` properties were not serialized correctly - #789 via @thedillonb
+* Fixed: Allow to download zip-attachments - #792 via @csware
+
+### New in 0.10.0 (released 2015/04/22)
+* Fixed: renamed methods to follow `GetAll` convention - #771 via @alfhenrik
+* Fixed: helper functions and cleanup to make using Authorization API easier to consume - #786 via @haacked
+
+**Breaking Changes:**
+ - As part of #771 there were many method which were returning collections
+   but the method name made it unclear. You might think that it wasn't much, but 
+   you'd be wrong. So if you have a method that no longer compile,
+   it is likely that you need to set the prefix to `GetAll` to re-disocver that API.
+ - `CommitComment.Position` is now a nullable `int` to prevent serialization issues.
+
 ### New in 0.9.0 (released 2015/04/04)
 * New: added `PullRequest.Files` APIs - #752 via @alfhenrik
 * Fixed: `PullRequestRequest` now supports `SortDirection` and `SortProperty` - #752 via @alfhenrik
