-    - The auto-hinter  has been completely rewritten  as a new module,
-      called the `auto-fitter',  which is now the default auto-hinting
-      module.  It consumes a lot less memory than its predecessor.
+    - The auto-hinter  has been replaced with a new module, called the
+      `auto-fitter'.  It consumes  less memory  than its  predecessor,
+      and it is  prepared to support non-latin scripts  better in next
+      releases.

    - George Williams  contributed code to read  kerning data from PFM
      files.

    - A new option `--ftversion' has been  added to freetype-config to
      return the FreeType version.

-    - The memory debugger has been updated to dump allocation statistics

-    - we removed a huge array of constant pointers to constant strings
-      in the 'psnames' module. The problem was that when compiled in PIC

+    - We removed a huge array of constant pointers to constant strings
+      in the `psnames' module.   The problem was that  compilations in
+      PIC mode (i.e.,  when generating a  Unix shared object/dll)  put
+      the array  into the non-shared  writable section of  the library
      since absolute pointers are not relocatable by nature.
      
-      This saves about 16Kb per process linked to FreeType. We also store
-      the array in a novel compressed way that saves about 20 Kb of code
-      as well.
+      This reduces the memory consumption by approximately 16KByte per
+      process linked  to FreeType.   We now also store  the array in a
+      compressed form (as a trie) which saves about 20KByte of code as
+      well.
