+2008-04-05, version 1.2.2
+=========================
+
+Implementation changes
+----------------------
+
+* Re-establish CLN-1.2.0 ABI and fix ARM build, both inadvertently broken in
+  the previous release.
+
+
+2008-03-24, version 1.2.1
+=========================
+
+Implementation changes
+----------------------
+
+* Fixed some bugs in the output of numbers larger than 2^32 decimal digits.
+
+Other changes
+-------------
+
+* 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).
+
+
+2006-08-08, version 1.1.13
+==========================
+
+* Compilation fixes for 64-bit brokenness introduced in last release.
+
+
+2006-08-06, version 1.1.12
+==========================
+
+Implementation changes
+----------------------
+
+* Fix rare assertion when printing quite large floats.
+
+Other changes
+-------------
+
+* Compilation fixes for several platforms: *BSD, Intel Mac, and MinGW.
+
+
+2005-11-23, version 1.1.11
+==========================
+
+Algorithmic changes
+-------------------
+
+* Considerably improved performance of number input.
+
+
+2005-10-22, version 1.1.10
+==========================
+
+Implementation changes
+----------------------
+
+* Removed the vptr of modular integer and univariate polynomial
+  classes in order to fix some crashes in that sector of CLN.  Code
+  using this needs to be recompiled.
+
+* Many more operator signatures make the integration of CLN types with
+  float/double easier.
+
+Other changes
+-------------
+
+* Several compilation fixes.
+
+* Made it possible to cross-compile CLN.
+
+
+2004-11-03, version 1.1.9
+=========================
+
+Algorithmic changes
+-------------------
+
+* Input of numbers in bases 2, 4, 8, 16 and 32 is now done in linear bit
+  complexity as opposed to O(N^2). Useful for all kinds of persistency.
+
+Implementation changes
+----------------------
+
+* Fixed several bugs in the integer input and output routines that could be
+  blamed for random crashes in the following cases: output in base 32 for
+  quite large numbers, input in base 2 for fixnums and input in base 3 for
+  fixnums on a 64 bit target.
+
+* Fixed crash when radix specifiers were used in input streams.
+
+* Speed up on x86_64 and ia64 by adding some inline assembly.
+
+Other changes
+-------------
+
+* Fixes for compilation on MacOS X and little endian Mips.
