 These variables now default to :UTF-8; in previous versions of CCL, they defaulted to NIL/:ISO-8859-1.
 
- 
+=== Access to high-resolution clock ===
+CCL:CURRENT-TIME-IN-NANOSECONDS returns the number of elapsed nanoseconds since some arbitrary point in time (likely system boot.)
+
+=== Accessing and manipulating character-encoding names and aliases ===
+New functions:
+
+ * (CCL:LIST-CHARACTER-ENCODINGS) 
+   returns a list of the "proper" names (keywords) of all defined character encodings.
+ * (CCL:LIST-CHARACTER-ENCODINGS :INCLUDE-ALIASES T) 
+   returns a list of all proper names and aliases of all defined character encodings.
+ * (CCL:DEFINE-CHARACTER-ENCODING-ALIAS alias existing) Tries to ensure that `alias` (a keyword) is recognized as an alias for the existing character encoding existing (which can be a CHARACTER-ENCODING object or a keyword that names one)
+ * (CCL:REMOVE-CHARACTER-ENCODING-ALIAS alias) Tries to ensure that `alias` (a keyword) is no longer recognized as an alias for any character encoding
+
+=== SIGNAL-EXTERNAL-PROCESS and external-process exit ===
+The function CCL:SIGNAL-EXTERNAL-PROCESS now takes an :ERROR-IF-EXITED keyword argument.  If the value of this argument is NIL and attempts to send the process fail because the process has already exited, CCL:SIGNAL-EXTERNAL-PROCESS quietly returns NIL.  The default value of the argument is T.
 
 
 === File options line can determine file's EXTERNAL-FORMAT ===
+If the first line of a text file contains an Emacs-style file-options line (";;; -*- .... -*-") and the file is opened for input with an :EXTERNAL-FORMAT of :INFERRED, then the value of the "coding" option (if present) is used to determine the file's CHARACTER-ENCODING.  (:EXTERNAL-FORMAT :INFERRED also tries to determine the file's line-termination as it has previously.)  When called with :EXTERNAL-FORMAT :DEFAULT, LOAD and COMPILE-FILE both arrange to call OPEN with an :EXTERNAL-FORMAT argument of :INFERRED.
