add compat for rsplit, updated readme

README.md

@@ -38,10 +38,14 @@ Currently, the `@compat` macro supports the following syntaxes:
 
 * `@compat split(str, splitter; keywords...)` - the Julia 0.4-style keyword-based `split` function
 
+* `@compat rsplit(str, splitter; keywords...)` - the Julia 0.4-style keyword-based `rsplit` function
+
 ## Type Aliases
 
 * `typealias AbstractString String` - `String` has been renamed to `AbstractString` [#8872](https://github.com/JuliaLang/julia/pull/8872)
 
+* For all unsigned integer types to their equivalents with uppercase `I`. [#8907](https://github.com/JuliaLang/julia/pull/8907)
+
 ## Renamed functions
 
 * `itrunc`, `iround`, `iceil`, `ifloor` are now accessed via `trunc(T, x)`, etc. [#9133](https://github.com/JuliaLang/julia/pull/9133)
