+============================================================================
+User visible changes for LZO -- a real-time data compression library
+============================================================================
+
+Changes in 2.03 (30 Apr 2008)
+  * Updated the ELF assembler sources to mark the stack as non-executable.
+  * Fixed a HP-UX 11 build issue with Itanium in ILP32 mode.
+  * Updated the configure system.
+
+Changes in 2.02 (17 Oct 2005)
+  * Updated the build and Autoconf scripts to fix some reported
+    compilation problems.
+
+Changes in 2.01 (27 Jun 2005)
+  * Changed the configure system to install the LZO library under the
+    name "liblzo2" so that parallel installation with LZO v1 is possible.
+  * Improved auto-configuration in miniLZO for some embedded targets like
+    Blackfin and H8/300 processors.
+
+Changes in 2.00 (30 May 2005)
+
+  [Library interface changes]
+  * The 'lzo_uint' typedef has been changed to match 'size_t', which means
+    it now is 64 bits on most 64-bit architectures. 32-bit machines
+    are not affected by this change.
+  * The formula for maximum expansion of incompressible data has changed.
+    See doc/LZO.FAQ. This is needed for some upcoming speed improvements,
+    and also for compatibility with our commercial LZO Professional product.
+  * The progress indicator callback interface has been revamped.
+  * All public header files now get installed into a "lzo" subdirectory, so
+    your applications should use #include <lzo/lzoXXX.h>.
+  * A number of (internal) macros have been renamed. See LZO_CFG_COMPAT
+    in <lzo/lzoconf.h> if your code depends on these.
+
+  [Speed]
+  * Small overall speedup by exploiting features like branch prediction
+    hints and explicit inline control present in modern C/C++ compilers.
+  * Significant speedup for 64-bit architectures like AMD64.
+
+  [Portability]
+  * LZO now fully supports the LLP64 programming model.
+  * LZO now fully supports the ILP64 and SILP64 programming models which
+    are used on some supercomputing architectures.
+  * Full Win64 support for AMD64 (aka x64) and IA64 (Itanium).
+  * Full 16-bit support for ancient DOS 286 protected mode, OS/2 1.x
+    and Windows 3.x.
+  * The LZO library now compiles and works on completely freestanding or
+    embedded systems as long as you have <limits.h> and <stddef.h> header
+    files. See the B/generic/build_freestanding.sh build script.
+
+  [Misc]
+  * The i386 assembler versions of the decompressors are now automatically
+    built and installed. See also asm/i386/00README.TXT.
+  * Added include file <lzo/lzo_asm.h> that provides prototypes for all
+    assembler functions.
+  * Under MacOS X, the configure script now will use the `-no-cpp-precomp'
+    compiler option in order to work around bugs in some versions of
+    Apple's native "smart" preprocessor.
+  * Worked around a preprocessor bug that is present in all compilers which
+    are based on the lcc compiler kit.
+  * Added simple B/generic/build.sh build script family.
+  * Added lots of new build scripts for various DOS/Windows compilers.
+
+  [Upgrade instructions from LZO v1 to LZO v2]
+  * On 64-bit architectures, revisit all uses of lzo_uint.
+  * Adapt for the maximum expansion change of incompressible data.
+  * If you use the progress callback then adapt for the new interface.
+  * Use #include <lzo/lzoXXX.h> or adjust your include path.
+  * Check your code for use of deprecated macros. Add a
+    #define LZO_CFG_COMPAT if necessary.
+  * Other than that LZO v2 should be fully source-compatible with LZO v1.
+    Of course, the compressed data is fully compatible as well.
+  * Re-compile and re-link your application.
+  * Enjoy the improvements!
+

+Changes in 1.08 (12 Jul 2002)
+  * Much better support for cross compiling.
+  * Straighten out ANSI-conforming compiler checks.
+  * Avoid harmless compiler warnings reported by -Wcast-align.

+    and Libtool versions.
+
+Changes in 1.07 (18 Oct 2000)
