 ** Dynamically expandable stacks
 
 Instead of allocating fixed stack sizes for running Scheme code, Guile
-now starts off each thread with only one or two pages of stack, and
-expands it dynamically as needed.  Guile will throw an exception for
-stack overflows at some user-defined limit.  See the manual for
-documentation on the GUILE_STACK_SIZE environment variable.

+This change allows users to write programs that use the stack as a data
 structure for pending computations, as it was meant to be, without
 reifying that data out to the heap.  Where you would previously make a
 loop that collect its results in reverse order only to re-reverse them
