Confluence Basic Macros plugin not upgraded to Confluence 5.1

It seems that the "Confluence Basic Macros" Plugin did not get installed since it does not seem to be compatible with confluence 5.1 (See https://marketplace.atlassian.com/plugins/confluence.macros.basic )

This means that the {noformat} macro does not work in 5.1, and the same presumably applies to any other macros in the Basic Macros plugin.
