 (Note: `linkBytecode` is also exposed via `solc` as `solc.linkBytecode`, but this usage is deprecated.)
 
-As of Solidity 0.4.11 the compiler supports [standard JSON input and output](https://solidity.readthedocs.io/en/develop/using-the-compiler.html#compiler-input-and-output-json-description) which outputs a *link references* map. This gives a map of library names to offsets in the bytecode to replace the addresses at.

This gives a map of library names to offsets in the bytecode to replace the addresses at. It also doesn't have the limitation on library file and contract name lengths.
 
 There is a method available in the `linker` module called `findLinkReferences` which can find such link references in bytecode produced by an older compiler:
