 =========================
 
 Implementation changes
 ----------------------
 
-* Added support for huge numbers...
+* Fixed some bugs in the output of numbers larger than 2^32 decimal digits.

+
+* Modifying C/C++ operators like +=, ++, etc. are now enabled by default.

+2008-01-19, version 1.2.0
+=========================
+
+Algorithmic changes
+-------------------
+
+* Save big amounts of memory in computation of some functions and constants by:
+    - Avoiding pre-computation of series terms and instead computing them in a
+      streamed way.
+    - Avoiding computation with excess precision in binary splitting algorithm
+      by coercion of intermediate integer values to floating-point as early as
+      possible.
+
+Implementation changes
+----------------------
+
+* Added support for huge numbers:
+    - intC used for all counter loops.
+    - intE is now a 64-bit type on all 64-bit platforms and even on selected
+      32-bit platforms.
+
+* CLN now uses C++ exceptions for error handling. The cl_abort() hook is not
+  supported any more. Please refer to the documentation to learn about existing
+  exception types.
+
+* Fixed a bug on i386 where comparing Z/2Z ring zeros returnd random results.
+
+* Removed cl_boolean. Use built-in C++ bool instead.
+
+Other changes
+-------------
+
+* Dropped the cln-config script. Please use pkg-config instead.
+
+* Updated infrastructure to that of libtool-1.5.24.
+
+* Changed encoding of all files to UTF-8.
+
+* Fix compilation issues with GCC-4.3.
+
+* Fix linking issues on platforms that don't feature weak symbols (like win32).
