 New in 3.0.0
 - Core
-  + Added a new embedding API in "parrot/api.h"
-  + Removed autovivification behavior from ResizablePMCArray
-  + Packfile PMCs have been refactored and can now generate usable bytecode
-  + Packfile manipulation functions now throw exceptions on error instead of
-    printing error details directly to stderr
-  + Improved Unicode support for file IO, environment variables, program names,
-    and command-line parameters
-  + Added experimental gdb pretty-printers in tools/dev for Parrot STRINGs and PMCs
-    (gdb 7.2 or later is required, as well as Python)
-  + Noticably faster build due to c2str.pl improvements
-  + Some bugs in our Digest::sha256 library and bit-related dynamic ops were
-    fixed by GCI student Nolan Lum. Both now work correctly on 32 and 64 bit systems
+  + A new embedding API is available in "parrot/api.h" and documented in
+    docs/pdd/pdd10_embedding.pod .
+  + Packfile PMCs were refactored and can now be used to produce runnable bytecode.
+  + Packfile manipulation code now throws embedder-friendly exceptions rather
+    than printing error details directly to stderr.

   + Major increases in test coverage of many core PMCs, dynamic PMCs and
-    dynamic opcodes thanks to Google Code-In and the interpid students it
-    attracted
+    dynamic opcodes resulted from GCI and the interpid students it attracted.
   + Jonathan "Duke" Leto set up Debian Linux x86_64 and sparc32 smokers
     in the GCC Compile Farm, which continually submit smoke reports with
-    different Configure.pl flags and compilers
-  + Makefile dependency checking is now tested, resulting in a more reliable
-    parallel build
+    a variety of configuration options and compilers.  Thanks, GCC!
+  + Makefile dependency checking is now automatically tested, resulting in a
+    more reliable parallel build.
+  + Coverage tests were improved for platforms with and without Devel::Cover.
