About CIL and MSIL and realationship between them

Question

I've strated to read an ECMA-335 specification and I don't understand the sense yet.

Question: What is the difference between CIL and MSIL?

Answer 1

It looks like MSIL is the former name. The new name is CIL.

CIL was originally known as Microsoft Intermediate Language (MSIL) during the beta releases of the .NET languages. Due to standardization of C# and the Common Language Infrastructure, the bytecode is now officially known as CIL.

From Common Intermediate Language on Wikipedia.
