Note that the example configs tend to represent the latest/greatest syntax & features, but existing configs should generally continue to work as is when upgrading -- if anything changes are made in Solr that might impact people with old configs when upgrading a special note will be found in the "Upgrading from Solr 1.XXX" section of the release notes. (such as the comment about the <httpCaching> directive in the "Upgrading from Solr 1.2" section, and about the json.nl=map option for JSON in "Upgrading from Solr 1.1") -Hoss
