 [section:ecv2 Class execution_context (version 2)]
 
-[note This class is enabled per default.]
+[warning __econtext__ is deprecated.]
+
+[note Include `execution_context.hpp` and pass define BOOST_EXECUTION_CONTEXT=2
+at compilers command-line in order to use __econtext__ (v2).]
+
+[note Segmented stacks (['segmented-stacks=on]), e.g. on demand growing stacks,
+are not supported by __econtext__ (v2).]
 
 Class __econtext__ encapsulates context switching and manages the associated
 context' stack (allocation/deallocation).
