+- soname bumped to 51
+- Update to stable version 1.6
+  Perfomance changes:
+  * heavy improvements for AVX2 capable platforms
+    (Haswell and later Intel CPUs) and work efficiency
+    improvements for multiple-socket machines.
+  
+  API changes:
+  * --threads N replaced by --pools N,N and --lookahead-slices N
+  * --[no-]rdoq-level N - finer control over RDOQ effort
+  * --min-cu-size N - trade-off compression for performance
+  * --max-tu-size N - trade-off compression for performance
+  * --[no-]temporal-layers - code unreferenced B frames in temporal
+    layer 1
+  * --[no-]cip aliases added for --[no-]constrained-intra
+  * Added support for new color transfer functions "smpte-st-2084"
+    and "smpte-st-428
+  * --limit-refs N was added, but not yet implemented
+  * Deprecated x265_setup_primitives() was removed from the public
+    API and is no longer exported DLLs
+  
+  Threading changes:
+  * The x265 thread pool has been made NUMA aware.
+  * The --threads  parameter, which used to specify a global
+    pool size, has been replaced with a --pools parameter which
+    allows you to specify a pool size per NUMA node (aka CPU socket
+    or package). The default is still to allocate one pool worker
+    thread per logical core on the machine, but with --pools one
+    can isolate those threads to a given socket.
+  * Other than socket isolation, the biggest visible change in the
+    NUMA aware thread pools is the increase in work efficiency.
+    The total utilization will generally decrease but the performance
+    will increase since worker threads spend less time context
+    switching.  Also, the threading of the lookahead was made more
+    work-efficient. Each lookahead job is a much larger piece of work.
+    Before (1.5):
+    disable thread pool: --threads 1
+    default thread pool: --threads 0
+    restrict to 4 threads: --threads 4
+    After (1.6):
+    disable thread pools: --pools 0
+    default thread pools: --pools *
+    restrict to 4 threads: --pools 4
+    restrict to 4 threads on socket 1: --pools -,4
+    restrict to all threads on socket 0: --pools +,-
+  
+  Multi-lib interface:
+  * In order to support runtime selection of a libx265
+    shared library, we have introduced an x265_api structure
+    and an x265_api_get() function. Applications which use
+    this interface to acquire the libx265 functional interface
+    will be able to use shim libraries to bind a particular build
+    of libx265 at run time. See the API documentation for full
+    details.
