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 . + * A number of (internal) macros have been renamed. See LZO_CFG_COMPAT + in 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 and 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 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 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. + * Fixed some sign extension problems on rather exotic machines where + sizeof(size_t) < sizeof(ptrdiff_t) and sizeof(lzo_uint) == sizeof(size_t) + * Updated the configure system to use the latest Autoconf, Automake + and Libtool versions. + +Changes in 1.07 (18 Oct 2000) + * Default to '--disable-shared' (I'm getting tired of Libtool's + shared library build problems, this time AIX was the culprit). + * Avoid some harmless compiler warnings. + +Changes in 1.06 (29 Nov 1999) + * Updated the configure system to use Autoconf 2.13, Automake 1.4 and + Libtool 1.3.3. This should hopefully fix the shared-library build + problems that were reported on some machines. + * Enhanced example programs a little bit. + +Changes in 1.05 (14 Apr 1998) + * Just a one-line change in the configure script to workaround + a HPUX and IRIX build problem. + +Changes in 1.04 (15 Mar 1998) + * Worked around a bug in the cpp preprocessor under HPUX 10.20. + * Adapted for Automake 1.2f and Libtool 1.1. + +Changes in 1.03 (18 Jan 1998) + * minor compression ratio improvement + * extended example program to show how to do overlapping compression + * assembler changes, added support for the nasm assembler + * better support for cross compiling + * some cleanups + +Changes in 1.02 (07 Dec 1997) + * improved LZO1X-999 and LZO1Y-999 compression ratio a little bit again + * introduced compression levels for LZO1X-999 and LZO1Y-999 + * added support for preset dictionaries + * implemented LZO1X-1(12): needs 16 KiB for compression + * new algorithm LZO1Z: this is another variant of LZO1X + * added example program: how to use preset dictionaries + * added example program: how to do in-place decompression + * added a little file-packer example program + * LZO now works cleanly under checkergcc + * strict 16-bit memory model is working (but not officially supported) + * shared libraries are supported on many platforms + * adapted for Automake 1.2d and Libtool 1.0h + +Changes in 1.01 (10 Aug 1997) + * improved LZO1X-999 and LZO1Y-999 compression ratio a little bit + * i386+gcc: significant speedup of the C version of the LZO1, LZO1A, + LZO1B and LZO1C decompressors + * added example programs that show how to generate pre-compressed data + * added Makefiles for DOS, Windows and OS/2 targets + +Changes in 1.00 (13 Jul 1997) + * added miniLZO - can be easily included in your project + * improved documentation, added LZO.FAQ + * added build scripts for many systems where Autoconf is not available: + Windows 3.1 (LIB+DLL), Windows 95/NT (LIB+DLL), DOS (16+32 bit), OS/2 + * adapted for Automake 1.2 and Libtool 1.0 + +Changes in 0.90 (27 Jun 1997): never released + * LZO now uses GNU Automake 1.0 - lots of configuration changes + * added LZO1X-1(11): this version needs only 8 KiB for compression + * implemented LZO1Y-1 + * added i386 assembler decompressors for MASM/TASM/WASM + * the name of some assembler functions changed + * the numeric value of some error codes changed + * portability fixes + +Changes in 0.29 (04 May 1997) + * Linux ELF shared library support + * workaround for gcc 2.7.2 optimizer bug under AIX + * added lzo_crc32() checksum + +Changes in 0.28 (22 Feb 1997) + * new algorithm LZO1Y: LZO1Y-999 and LZO1Y decompressor + * added lzo1x_optimize() and lzo1y_optimize() + * minor speedup in assembler decompressors (i386+gcc) + * ltest.c rewritten + +Changes in 0.27 (19 Jan 1997) + * fixed a bug in LZO1B-999 and LZO1C-999 that could produce + invalid compressed data in very rare cases + +Changes in 0.26 (18 Jan 1997): never released + * implemented LZO1B-999 + * renamed LZO1D to LZO2A (also updated all docs) + * some cleanups + +Changes in 0.25 (28 Dec 1996): never released + * some portability fixes (LZO now works on my old Atari ST :-) + * adapted for Autoconf 2.12 + +Changes in 0.24 (30 Nov 1996): never released + * improved performance of LZO1X assembler decompressor on a Pentium (i386+gcc) + +Changes in 0.23 (23 Nov 1996) + * added LZO1C, LZO1F and LZO1X decompressors in assembler (i386+gcc) + * added corresponding LZO_PUBLIC to all LZO_EXTERN functions + * added support for Microsoft C 7.0 (16-bit DOS) + * introduced lzo_uint32.
