In this chapter, Publishing has been restructured into 2 clear parts: Registering an add-on in the centralized catalog and Using your customized catalog.
Also, a new tutorial Adding a supported language instructs you to extend the supported languages by portal extension.
One new chapter for ACME add-on has been included in this guide.
You will find all information, from installation/uninstallation (for administrators) to common Content features (for site readers and editors) and customization topics (for developers).
As of 4.1, JODConverter is configured only in exo.properties, so there is no longer overlap with customized scripts.
The variable EXO_JODCONVERTER_OFFICEHOME becomes obsolete, so check the section for the new configuration pattern.
