 ## 4.1-dev
 
 Since the Facebook PHP SDK didn't follow SemVer in version 4.x, the master branch was going to be released as 4.1. However, the SDK switched to SemVer in v5.0. So any references on the internet to version 4.1 can be assumed to be an alias to version `5.0.0`
 
-
 ## 4.0.x
 
 Version 4.0 of the Facebook PHP SDK did not follow [SemVer](http://semver.org/). The versioning format used was as follows: `4.MAJOR.(MINOR|PATCH)`. The `MINOR` and `PATCH` versions were squashed together.
