What is correct version for EL 2.2

[Ivan]

Hi,
    While compiling the latest Tomcat 7, I got some errors with our el spec
1.0. It seems that we need to create a new EL package, currently, the EL is
distributed within the JSP spec, so what is the proper version for it, 2.2
or 2.1-MR2 ?
   Thanks !
