- Added support for file-backed memory heaps
(for details please take a look at man/memkind_pmem.3)
- Added autohbw library, that intercepts the standard heap allocations,

configure time parameter or enviromental variable
(for details please take a look at MEMKIND_ARENA_NUM_PER_KIND section

multithreaded, PMTT, nagtive, stress).
* Fri Jan 9 2015 Christopher Cantalupo <[email protected]> v0.2.0
- Bumped memkind ABI version to 0:1:0.
- Removed memkind_get_kind_for_free() from externally facing API's. Instead if
memkind_free() is called with zero passed for the kind then
memkind_get_kind_for_free() is called internally.
- Moved to single callback memkind_partition_mmap() to simplify
jemalloc modifications.
- Added hooks for setting file descriptor and offset for mmap enabling
file-backed memory kinds.
- Added a void pointer called "priv" to memkind structure for storing data for
user-defined kinds.
- Removed call to sched_getcpu(), now thread id is hashed to determine the arena
index.
- Added weak symbol hooks for decorating the heap management functions.
- Fixed several issues with init.d/memkind script and spec file scriptlets that
are exposed by SLES-12.
- Introduced an example library called numakind.
The numakind library will allocate from the closest NUMA node to a thread as
measured when that thread makes its first allocation call.

gigabyte pages are not available.

- Increased test code coverage significantly.
- Fixed bug in memkind_error_message() for MEMKIND_ERROR_TOOMANY.
- Removed memkind_arena_free() API since it was redundant with memkind_default_free().
- Static memkind structs are now declared as extern in the headers and defined in the
source files files rather than being statically defined in the headers.
* Thu Oct 30 2014 Christopher Cantalupo <[email protected]> v0.0.9
- Now building with autotools.
- Updated documentation.
- Fixed typo in copyright.
- Fixed test scripts to properly handle return code of each test.

- Added GBTLB functionality, code clean up, documentation updates,
examples directory. Examples includes stream modified to use
memkind interface. Code coverage still lacking, and documentation
incomplete.
