The 4.10.3 Hotfix resolves 16 issues and further helps to solidify what is already one of our most stable UE4 releases, and resolves a few major issues as well as a common installation error. Feel free to continue the discussion about this release on the 4.10 announcement thread. Other recent fixes that could not be merged into the 4.10 branch will be available in the upcoming 4.11 release.
