CVE-2014-4607. - - * Removed support for ancient configurations like 16-bit "huge" pointers - - LZO now requires a flat 32-bit or 64-bit memory model. - * Assorted cleanups. - -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.
