We made a small change to the AdWords API WSDL files today, changing the declared type of KeywordId from int (32 bit) to long (64 bit). The server has treated keyword IDs as longs since our launch, and the online docs declared them as such. Only the WSDL was in error.
Existing client code should see no effect of this. If you regenerate proxy code from the WSDL the type will change, and you may get some minor compile time errors about type conversions. We also are updating the new Java client library and this update will be available shortly.
Many thanks to our user Sabina for pointing out the discrepancy.
