- Dask.compute traverses Python collections (:pr:`1975`)
- Structural sharing between graphs in dask.array and dask.delayed (:pr:`1985`)


0.13.0 / 2017-01-02
-------------------

Array
+++++

- Mandatory dtypes on dask.array.  All operations maintain dtype information
  and UDF functions like map_blocks now require a dtype= keyword if it can not
  be inferred.  (:pr:`1755`)
- Support arrays without known shapes, such as arises when slicing arrays with
  arrays or converting dataframes to arrays (:pr:`1838`)
- Support mutation by setting one array with another (:pr:`1840`)
- Tree reductions for covariance and correlations.  (:pr:`1758`)
- Add SerializableLock for better use with distributed scheduling (:pr:`1766`)
- Improved atop support (:pr:`1800`)
- Rechunk optimization (:pr:`1737`), (:pr:`1827`)

Bag
+++

DataFrame
+++++++++

- Add ``shift`` (:pr:`1773`)
- Add Parquet support (:pr:`1782`) (:pr:`1792`) (:pr:`1810`), (:pr:`1843`),
  (:pr:`1859`), (:pr:`1863`)
- Add missing methods combine, abs, autocorr, sem, nsmallest, first, last,
  prod, (:pr:`1787`)

  drop_duplicates) (:pr:`1808`), (:pr:`1823`) (:pr:`1828`)
- Add delitem and copy to DataFrames, increasing mutation support (:pr:`1858`)

Delayed
+++++++

- Changed behaviour for ``delayed(nout=0)`` and ``delayed(nout=1)``:
  ``delayed(nout=1)`` does not default to ``out=None`` anymore, and
  ``delayed(nout=0)`` is also enabled. I.e. functions with return
  tuples of length 1 or 0 can be handled correctly. This is especially
  handy, if functions with a variable amount of outputs are wrapped by
  ``delayed``. E.g. a trivial example:
  ``delayed(lambda *args: args, nout=len(vals))(*vals)``

Core
++++

0.11.0 / 2016-08-24
-------------------

Major Points
++++++++++++

DataFrames now enforce knowing full metadata (columns, dtypes) everywhere.
Previously we would operate in an ambiguous state when functions lost dtype
information (such as ``apply``).  Now all dataframes always know their dtypes
and raise errors asking for information if they are unable to infer (which
they usually can).  Some internal attributes like ``_pd`` and
``_pd_nonempty`` have been moved.

The internals of the distributed scheduler have been refactored to
transition tasks between explicit states.  This improves resilience,
reasoning about scheduling, plugin operation, and logging.  It also makes
the scheduler code easier to understand for newcomers.

Breaking Changes
++++++++++++++++

- The ``distributed.s3`` and ``distributed.hdfs`` namespaces are gone.  Use
  protocols in normal methods like ``read_text('s3://...'`` instead.
- ``Dask.array.reshape`` now errs in some cases where previously it would have
  create a very large number of tasks


0.10.2 / 2016-07-27
-------------------

- More Dataframe shuffles now work in distributed settings, ranging from
  setting-index to hash joins, to sorted joins and groupbys.
- Dask passes the full test suite when run when under in Python's
  optimized-OO mode.
- On-disk shuffles were found to produce wrong results in some
  highly-concurrent situations, especially on Windows.  This has been resolved
  by a fix to the partd library.
- Fixed a growth of open file descriptors that occurred under large data
  communications
- Support ports in the ``--bokeh-whitelist`` option ot dask-scheduler to better
  routing of web interface messages behind non-trivial network settings
- Some improvements to resilience to worker failure (though other known
  failures persist)
- You can now start an IPython kernel on any worker for improved debugging and
  analysis
- Improvements to ``dask.dataframe.read_hdf``, especially when reading from
  multiple files and docs


0.10.0 / 2016-06-13
-------------------

Major Changes
+++++++++++++

- This version drops support for Python 2.6
- Conda packages are built and served from conda-forge
- The ``dask.distributed`` executables have been renamed from dfoo to dask-foo.
  For example dscheduler is renamed to dask-scheduler
- Both Bag and DataFrame include a preliminary distributed shuffle.

Bag
++++

- Add task-based shuffle for distributed groupbys
- Add accumulate for cumulative reductions

DataFrame
+++++++++

- Add a task-based shuffle suitable for distributed joins, groupby-applys, and
  set_index operations.  The single-machine shuffle remains untouched (and
  much more efficient.)
- Add support for new Pandas rolling API with improved communication
  performance on distributed systems.
- Add ``groupby.std/var``
- Pass through S3/HDFS storage options in ``read_csv``
- Improve categorical partitioning
- Add eval, info, isnull, notnull for dataframes

Distributed
+++++++++++

- Rename executables like dscheduler to dask-scheduler
- Improve scheduler performance in the many-fast-tasks case (important for
  shuffling)
- Improve work stealing to be aware of expected function run-times and data
  sizes.  The drastically increases the breadth of algorithms that can be
  efficiently run on the distributed scheduler without significant user
  expertise.
- Support maximum buffer sizes in streaming queues
- Improve Windows support when using the Bokeh diagnostic web interface
- Support compression of very-large-bytestrings in protocol
- Support clean cancellation of submitted futures in Joblib interface

Other
+++++

- All dask-related projects (dask, distributed, s3fs, hdfs, partd) are now
  building conda packages on conda-forge.
- Change credential handling in s3fs to only pass around delegated credentials
  if explicitly given secret/key.  The default now is to rely on managed
  environments.  This can be changed back by explicitly providing a keyword
  argument.  Anonymous mode must be explicitly declared if desired.


0.9.0 / 2016-05-11
------------------

API Changes
+++++++++++

- ``dask.do`` and ``dask.value`` have been renamed to ``dask.delayed``
- ``dask.bag.from_filenames`` has been renamed to ``dask.bag.read_text``
- All S3/HDFS data ingest functions like ``db.from_s3`` or
  ``distributed.s3.read_csv`` have been moved into the plain ``read_text``,
  ``read_csv functions``, which now support protocols, like
  ``dd.read_csv('s3://bucket/keys*.csv')``

Array
+++++

- Add support for ``scipy.LinearOperator``
- Improve optional locking to on-disk data structures
- Change rechunk to expose the intermediate chunks

Bag

  ``solve``, ``solve_triangular``, ``eye``, ``lstsq``, ``diag``, ``corrcoef``.

Bag

- Add range function
- drop ``from_hdfs`` function (better functionality now exists in hdfs3 and
  distributed projects)

+++++++++

- Refactor ``dask.dataframe`` to include a full empty pandas dataframe as
  metadata.  Drop the ``.columns`` attribute on Series
- Add Series categorical accessor, series.nunique, drop the ``.columns``
  attribute for series.
- ``read_csv`` fixes (multi-column parse_dates, integer column names, etc. )
- Internal changes to improve graph serialization

Other
+++++

- Documentation updates

This release also includes a deprecation warning for ``dask.distributed``, which
will be removed in the next version.

Future development in distributed computing for dask is happening here:
https://distributed.dask.org . General feedback on that project is most
welcome from this community.
