Previously released versions of the module merged walking the taxonomy tree with rendering for most situations, leaving little room for themeability.
This has been split in three parts:
Data is obtained in the new _taxonomy_context_build_tree($context→tid, $base)
Rendering is performed in the new theme_taxonomy_context_children_list($tid, $base = FALSE)
A deprecation warning is inserted in the obsolete taxonomy_context_show_children
This has been split in three parts:
Data is obtained in taxonomy_context_nodes($tid)
Rendering is performed in the new theme_taxonomy_context_nodes()
A deprecation warning is inserted in the obsolete taxonomy_context_show_nodes
