+- specfile:
+  * remove devel requirement
+
+- update to version 0.12.1:
+  * Make sure that any exception triggered when serializing jobs in
+    the queue will be wrapped as a PicklingError as in past versions
+    of joblib.
+  * Fix kwonlydefaults key error in filter_args (#715)
+
+- changes from version 0.12:
+  * Implement the 'loky' backend with @ogrisel. This backend relies on
+    a robust implementation of concurrent.futures.ProcessPoolExecutor
+    with spawned processes that can be reused accross the Parallel
+    calls. This fixes the bad interation with third paty libraries
+    relying on thread pools, described in
+    https://pythonhosted.org/joblib/parallel.html#bad-interaction-of-multiprocessing-and-third-party-libraries
+  * Limit the number of threads used in worker processes by
+    C-libraries that relies on threadpools. This functionality works
+    for MKL, OpenBLAS, OpenMP and Accelerated.
+  * Prevent numpy arrays with the same shape and data from hashing to
+    the same memmap, to prevent jobs with preallocated arrays from
+    writing over each other.
+  * Reduce overhead of automatic memmap by removing the need to hash
+    the array.
+  * Make Memory.cache robust to PermissionError (errno 13) under
+    Windows when run in combination with Parallel.
+  * The automatic array memory mapping feature of Parallel does no
+    longer use /dev/shm if it is too small (less than 2 GB). In
+    particular in docker containers /dev/shm is only 64 MB by default
+    which would cause frequent failures when running joblib in Docker
+    containers.
+  * Make it possible to hint for thread-based parallelism with
+    prefer='threads' or enforce shared-memory semantics with
+    require='sharedmem'.
+  * Rely on the built-in exception nesting system of Python 3 to
+    preserve traceback information when an exception is raised on a
+    remote worker process. This avoid verbose and redundant exception
+    reports under Python 3.
+  * Preserve exception type information when doing nested Parallel
+    calls instead of mapping the exception to the generic
+    JoblibException type.
+  * Introduce the concept of 'store' and refactor the Memory internal
+    storage implementation to make it accept extra store backends for
+    caching results. backend and backend_options are the new options
+    added to Memory to specify and configure a store backend.
+  * Add the register_store_backend function to extend the store
+    backend used by default with Memory. This default store backend is
+    named 'local' and corresponds to the local filesystem.
+  * The store backend API is experimental and thus is subject to
+    change in the future without deprecation.
+  * The cachedir parameter of Memory is now marked as deprecated, use
+    location instead.
+  * Add support for LZ4 compression if lz4 package is installed.
+  * Add register_compressor function for extending available
+    compressors.
+  * Allow passing a string to compress parameter in dump funtion. This
+    string should correspond to the compressor used (e.g. zlib, gzip,
+    lz4, etc). The default compression level is used in this case.
+  * Allow parallel_backend to be used globally instead of only as a
+    context manager. Support lazy registration of external parallel
+    backends
