+ * Version 1.9-rc1
+
+ This release:
+ - Switches the default instruction set for memcpy, memmove and memset
+ implementations on x86 to AVX512, and introduces numerous performance
+ improvements for those operations on AVX and SSE2 fallback paths.
+ - Optimizes transactional allocations in libpmemobj by avoiding one
+ extraneous cache miss and reducing the amount of work required to perform
+ a reservation.
+ - Introduces a new API in libpmemobj, pmemobj_tx_set_failure_behavior,
+ that enables the application to control the behavior of aborting
+ transactions.
+ - Improves performance of pool creation on Windows by avoiding expensive
+ physical page allocation during file allocation.
+
+ Other changes:
+ - pmem: mem[cpy|set] optimization when eADR is available
+ - obj: detect msync failures in non-pmem variants of mem[cpy|move|set]
+
+ Notable bug fixes:
+ - core: fix Last_errormsg_get when NO_LIBPTHREAD is defined
+ - pmem: read Unsafe Shutdown Count from region instead of interleave set
+ - common: fix deep_flushes failing on platforms that don't need them
+ - pmem: fix data cache flush on ppc64
+ - obj: fix run allocated recalculation
