- 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
