+* 1.5.6, March 1, 2006
+ - The low-level DER/BER coding system was redesigned and rewritten
+ - Portions of the certificate code were cleaned up internally
+ - Use macros to substantially clean up the GCC assembly code
+ - Added 32-bit x86 assembly for Visual C++ (by Luca Piccarreta)

+
+* 1.5.5, February 4, 2006
+ - Fixed a potential infinite loop in the memory pool code (Matt Johnston)
+ - Made Pooling_Allocator::Memory_Block an actual class of sorts
+ - Some small optimizations to the division and modulo computations
+ - Cleaned up the implementation of some of the BigInt operators
+ - Reduced use of dynamic memory allocation in low-level BigInt functions
+ - A few simplifications in the Randpool mixing function

+ - Added a real credits file
+
+* 1.5.4, January 29, 2006
+ - Integrated x86 and amd64 assembly code, contributed by Luca Piccarreta
+ - Fixed a memory access off-by-one in the Karatsuba code
+ - Changed Pooling_Allocator's free list search to a log(N) algorithm
+ - Merged ModularReducer with its only subclass, Barrett_Reducer
+ - Fixed sign-handling bugs in some of the division and modulo code
+ - Renamed the module description files to modinfo.txt
+ - Further cleanups in the initialization code
+ - Removed BigInt::add and BigInt::sub
+ - Merged all the division-related functions into just divide()
+ - Modified the <mp_asmi.h> functions to allow for better optimizations
+ - Made the number of bits polled from an EntropySource user configurable
+ - Avoid including <algorithm> in <botan/secmem.h>

+
+* 1.5.3, January 24, 2006
+ - Many optimizations in the low-level multiple precision integer code

+ - Fixed a bug in the decompression modules; found and patched by Matt Johnston
+ - New Windows mutex module (mux_win32), by Luca Piccarreta
+ - Changed the Windows timer module to use QueryPerformanceCounter
+ - mem_pool.cpp was using std::set iterators instead of std::multiset ones
+ - Fixed a bug in X509_CA preventing users from disabling particular extensions
