The help for "Context Information" was updated to the following:
The contexts to propagate to threads: Classloader, JNDI, Security, or WorkArea. Context propagation can be enabled or disabled. If enabled, the selected contexts are propagated. If disabled, none of the contexts are propagated, even if they are selected. The default value is Enabled, with all four contexts selected.
This change was made in the help for both "Edit Context Service" and "New Context Service". This change was committed to main-docs in svn revision 61142 and appeared in version 4.0-b27 of main-docs.
There have been no changes to main-docs since.
