• Allow to alter DEFAULT/MAX_NTHREADS values in test_malloc/stack
• Allow to select almost-non-blocking stack implementation explicitly
• Annotate AO_malloc with 'alloc_size' and 'malloc' attributes
• Avoid misleading 'AO_t undefined' error if wrong atomic_ops.h included
• Define AO_TS_SET to 1 (true) if GCC atomic_test_and_set is used
• Disable workaround in stack_pop_acquire that was needed for ancient Clang
• Do not define AO_GCC_FORCE_HAVE_CAS for Clang 3.8+ (Aarch64)
• Do not disallow to define double_load using built-in atomics (Aarch64)
• Do not expose AO_GCC_FORCE_HAVE_CAS macro to client code (GCC)
• Do not install documentation if configure --disable-docs (new option)
• Do not produce .tar.bz2 distribution file (configure)
• Eliminate '-pedantic is not an option that controls warnings' GCC message
• Eliminate data race in cons() of test_malloc
• Eliminate GCC-5 ASan global-buffer-overflow false positive for AO_stack_bl
• Fill in allocated memory with values depending on thread id (test_malloc)
• Fix 'bad register name %sil' assembler error (GCC-4.4/x86)
• Fix 'unknown attribute no_sanitize' compiler warning for GCC
• Fix AO_malloc for sizes near CHUNK_SIZE
• Fix memory leak in test_malloc
• Fix test failures for Clang-3.8 and older (Aarch64)
• Fix test_stack failure if AO_PREFER_BUILTIN_ATOMICS (GCC/Aarch64)
• Fix typo in AO_REAL_NEXT_PTR comment
• Increase the default number of threads to 16 in test_malloc/stack
• Mark unallocated/freed memory as inaccessible using ASan functionality
• New macro (DONT_USE_MMAP) to support testing as if mmap() is unavailable
• New macro to select stack implementation based on CAS-double
• Place no_sanitize attributes in a GCC-compliant way
• Prevent too long run of test_atomic_generalized (especially with TSan)
• Simplify '#if' expressions in gcc/x86.h (code refactoring)
• Test smallest allocation of large type (test_malloc)
• Use builtin_expect in atomic_ops_malloc
• Use built-in atomics for load/store/CAS for Clang by default (Aarch64)
• Use double-word atomic intrinsics for recent Clang versions (gcc/x86.h)
• Use GCC atomic intrinsics for Hexagon (clang 3.9+)
• Use generalized double-wide load/store if AO_PREFER_GENERALIZED (Aarch64)
• Workaround 'unused result' code defects in atomic_ops.c, list_atomic
• Workaround Thread Sanitizer (TSan) false positive warnings

Also, includes 7.4.8 changes
