+============================================================================
+User visible changes for LZO -- a real-time data compression library
+============================================================================
+
+Changes in 2.06 (12 Aug 2011)
+ * Some minor optimizations for big-endian architectures.
+ * Fixed overly strict malloc() misalignment check in examples.
+
+Changes in 2.05 (23 Apr 2011)
+ * Converted the configure system to non-recursive Automake.
+ * Applied some overdue speed optimizations for modern x86/x64 architectures
+ and current compilers like gcc 4.6 and MSVC 2010.
+
+Changes in 2.04 (31 Oct 2010)
+ * Fixed a gcc-4.5 aliasing issue in lzo_init().
+ * Updated the configure system.
+ * Assorted cleanups.
+
+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!
+

+ * Much better support for cross compiling.
+ * Straighten out ANSI-conforming compiler checks.
+ * Avoid harmless compiler warnings reported by -Wcast-align.
+ * Fixed some sign extension problems on rather exotic machines where

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