The errata are the additional fixes or changes to the specification that didn't make it in the specification or were found after the specification :)

asked why the errata can't be found on the ECMA website, Brendan
replied ECMA only publishes final stuff.
So if you're looking for the ECMAscript errata or erratum, here it is:
