+---------------------

+This release signifies a major change in libConfuse.  On out-of-memory
+conditions at run time, invalid API input, and some other odd use-cases,
+libConfuse will no longer `assert()`.  Instead, `NULL` or `CFG_FAIL` is
+returned with an error code for you to handle.  For some users this will
+completely change how your application works, so heads up!  The library
+ABI version has also been stepped due to this.
 
 Special thanks in this release goes out to Frank Hunleth, Peter Rosin
 and David Grayson for their tireless efforts in helping improve this
