* Wed Aug 08 2018
  - Ensure neutrality of description. Remove future visions.
    Use noun phrase in summary.
* Sat Aug 04 2018
  - Update to 0.23.4
    * Python 3.7 with Windows gave all missing values for rolling variance calculations (:issue:`21813`)
    * Bug where calling :func:`DataFrameGroupBy.agg` with a list of functions including ``ohlc`` as the non-initial element would raise a ``ValueError`` (:issue:`21716`)
    * Bug in ``roll_quantile`` caused a memory leak when calling ``.rolling(...).quantile(q)`` with ``q`` in (0,1) (:issue:`21965`)
    * Bug in :func:`Series.clip` and :func:`DataFrame.clip` cannot accept list-like threshold containing ``NaN`` (:issue:`19992`)
* Sat Jul 14 2018
  - update to version 0.23.3:
    * This release fixes a build issue with the sdist for Python 3.7
      (GH21785) There are no other changes.
* Sat Jul 07 2018
  - update to version 0.23.2:
    * Fixed Regressions
      + Fixed regression in to_csv() when handling file-like object
      incorrectly (GH21471)
      + Re-allowed duplicate level names of a MultiIndex. Accessing a
      level that has a duplicate name by name still raises an error
      + Bug in both DataFrame.first_valid_index() and
      Series.first_valid_index() raised for a row index having
      duplicate values (GH21441)
      + Fixed printing of DataFrames with hierarchical columns with long
      names (GH21180)
      + Fixed regression in reindex() and groupby() with a MultiIndex or
      multiple keys that contains categorical datetime-like values
      + Fixed regression in unary negative operations with object dtype
      + Bug in Timestamp.ceil() and Timestamp.floor() when timestamp is
      a multiple of the rounding frequency (GH21262)
      + Fixed regression in to_clipboard() that defaulted to copying
      dataframes with space delimited instead of tab delimited
    * Build Changes
      + The source and binary distributions no longer include test data
      files, resulting in smaller download sizes. Tests relying on
      these data files will be skipped when using
      pandas.test(). (GH19320)
    * Bug Fixes
    * Conversion
      + Bug in constructing Index with an iterator or generator
      + Bug in Series.nlargest() for signed and unsigned integer dtypes
      when the minimum value is present (GH21426)
    * Indexing
      + Bug in Index.get_indexer_non_unique() with categorical key
      + Bug in comparison operations for MultiIndex where error was
      raised on equality / inequality comparison involving a
      MultiIndex with nlevels == 1 (GH21149)
      + Bug in DataFrame.drop() behaviour is not consistent for unique
      and non-unique indexes (GH21494)
      + Bug in DataFrame.duplicated() with a large number of columns
      causing a ‘maximum recursion depth exceeded’ (GH21524).
    * I/O
      + Bug in read_csv() that caused it to incorrectly raise an error
      when nrows=0, low_memory=True, and index_col was not None
      + Bug in json_normalize() when formatting the record_prefix with
      integer columns (GH21536)
    * Categorical
      + Bug in rendering Series with Categorical dtype in rare
      conditions under Python 2.7 (GH21002)
    * Timezones
      + Bug in Timestamp and DatetimeIndex where passing a Timestamp
      localized after a DST transition would return a datetime before
      the DST transition (GH20854)
      + Bug in comparing DataFrame`s with tz-aware :class:`DatetimeIndex
      columns with a DST transition that raised a KeyError (GH19970)
    * Timedelta
      + Bug in Timedelta where non-zero timedeltas shorter than 1
      microsecond were considered False (GH21484)
* Wed Jun 13 2018
  - Update to 0.23.1
    + Fixed Regressions
    * Reverted change to comparing a Series holding datetimes and a object
    * Reverted the ability of to_sql() to perform multivalue inserts as this caused regression in certain cases (GH21103). In the future this will be made configurable.
    * Fixed regression in the and DatetimeIndex.time attributes in case of timezone-aware data: DatetimeIndex.time returned a tz-aware time instead of tz-naive (GH21267) and returned incorrect date when the input date has a non-UTC timezone (GH21230).
    * Fixed regression in when called with None values in nested levels in JSON, and to not drop keys with value as None (GH21158, GH21356).
    * Bug in to_csv() causes encoding error when compression and encoding are specified (GH21241, GH21118)
    * Bug preventing pandas from being importable with -OO optimization (GH21071)
    * Bug in Categorical.fillna() incorrectly raising a TypeError when value the individual categories are iterable and value is an iterable (GH21097, GH19788)
    * Fixed regression in constructors coercing NA values like None to strings when passing dtype=str (GH21083)
    * Regression in pivot_table() where an ordered Categorical with missing values for the pivot’s index would give a mis-aligned result (GH21133)
    * Fixed regression in merging on boolean index/columns (GH21119).
    + Performance Improvements

      > Bug in pandas.core.groupby.GroupBy.ffill() and pandas.core.groupby.GroupBy.bfill() where the fill within a grouping would not always be applied as intended due to the implementations’ use of a non-stable sort (GH21207)
      > Bug in pandas.core.groupby.GroupBy.rank() where results did not scale to 100% when specifying method='dense' and pct=True
      > Bug in pandas.DataFrame.rolling() and pandas.Series.rolling() which incorrectly accepted a 0 window size rather than raising (GH21286)
    * Data-type specific
      > Bug in Series.str.replace() where the method throws TypeError on Python 3.5.2 (:issue: 21078)
      > Bug in Timedelta: where passing a float with a unit would prematurely round the float precision (:issue: 14156)
      > Bug in pandas.testing.assert_index_equal() which raised AssertionError incorrectly, when comparing two CategoricalIndex objects with param check_categorical=False (GH19776)
    * Sparse
      > Bug in SparseArray.shape which previously only returned the shape SparseArray.sp_values (GH21126)
    * Indexing
      > Bug in Series.reset_index() where appropriate error was not raised with an invalid level name (GH20925)
      > Bug in interval_range() when start/periods or end/periods are specified with float start or end (GH21161)
      > Bug in MultiIndex.set_names() where error raised for a MultiIndex with nlevels == 1 (GH21149)
      > Bug in IntervalIndex constructors where creating an IntervalIndex from categorical data was not fully supported (GH21243, issue:21253)
      > Bug in MultiIndex.sort_index() which was not guaranteed to sort correctly with level=1; this was also causing data misalignment in particular DataFrame.stack() operations (GH20994, GH20945, GH21052)
    * Plotting
      > New keywords (sharex, sharey) to turn on/off sharing of x/y-axis by subplots generated with pandas.DataFrame().groupby().boxplot() (:issue: 20968)
    * I/O
      > Bug in IO methods specifying compression='zip' which produced uncompressed zip archives (GH17778, GH21144)
      > Bug in DataFrame.to_stata() which prevented exporting DataFrames to buffers and most file-like objects (GH21041)
      > Bug in read_stata() and StataReader which did not correctly decode utf-8 strings on Python 3 from Stata 14 files (dta version 118) (GH21244)
      > Bug in IO JSON read_json() reading empty JSON schema with orient='table' back to DataFrame caused an error (GH21287)
    * Reshaping
      > Bug in concat() where error was raised in concatenating Series with numpy scalar and tuple names (GH21015)
      > Bug in concat() warning message providing the wrong guidance for future behavior (GH21101)
    * Other
      > Tab completion on Index in IPython no longer outputs deprecation warnings (GH21125)
      > Bug preventing pandas being used on Windows without C++ redistributable installed (GH21106)

    html and pdf provided by upstream, just point to the URL
* Thu Jan 11 2018
  - Drop commented code to allow us py3 only build
* Wed Jan 03 2018
  - specfile:
    * update copyright year
  - update to version 0.22.0:
    * Pandas 0.22.0 changes the handling of empty and all-NA sums and
      products. The summary is that
      + The sum of an empty or all-NA Series is now 0
      + The product of an empty or all-NA Series is now 1
      + We’ve added a min_count parameter to .sum() and .prod()
      controlling the minimum number of valid values for the result to
      be valid. If fewer than min_count non-NA values are present, the
      result is NA. The default is 0. To return NaN, the 0.21
      behavior, use min_count=1.
* Sat Dec 16 2017

    * Support for a datetime64[ns] with timezones as a first-class
      dtype, see here
    * The default for to_datetime will now be to raise when presented
      with unparseable formats, previously this would return the
      original input.  Also, date parse functions now return consistent
      results. See here

      IPython itself (only for IPython v3.0 or greater). This
      eliminates the duplicate scroll bars that appeared in the
      notebook with large frames (GH10231).
      Note that the notebook has a toggle output scrolling feature to
      limit the display of very large frames (by clicking left of the
      output). You can also configure the way DataFrames are displayed
      using the pandas options, see here here.
      + axis parameter of DataFrame.quantile now accepts also index and
      column. (GH9543)
    * API Changes

* Tue May 19 2015
  - Update to version 0.16.1
    * Highlights
    - Support for a ``CategoricalIndex``, a category based index
    - New section on how-to-contribute to pandas
    - Revised "Merge, join, and concatenate" documentation,
      including graphical examples to make it easier to understand
      each operations
    - New method sample for drawing random samples from Series,
      DataFrames and Panels.
    - The default Index printing has changed to a more uniform
    - BusinessHour datetime-offset is now supported
    * Enhancements
    - BusinessHour`offset is now supported, which represents
      business hours starting from 09:00 - 17:00 on BusinessDay by
    - DataFrame.diff now takes an axis parameter that determines the
      direction of differencing
    - Allow clip, clip_lower, and clip_upper to accept array-like
      arguments as thresholds (This is a regression from 0.11.0).
      These methods now have an axis parameter which determines
      how the Series or DataFrame will be aligned with the
    - DataFrame.mask() and Series.mask() now support same keywords
      as where
    - drop function can now accept errors keyword to suppress
      ValueError raised when any of label does not exist in the
      target data.
    - Allow conversion of values with dtype datetime64 or timedelta64
      to strings using astype(str)
    - get_dummies function now accepts sparse keyword.  If set to
      True, the return DataFrame is sparse, e.g. SparseDataFrame.
    - Period now accepts datetime64 as value input.
    - Allow timedelta string conversion when leading zero is
      missing from time definition, ie 0:00:00 vs 00:00:00.
    - Allow Panel.shift with axis='items'
    - Trying to write an excel file now raises NotImplementedError
      if the DataFrame has a MultiIndex instead of writing a broken
      Excel file.
    - Allow Categorical.add_categories to accept Series or np.array.
    - Add/delete str/dt/cat accessors dynamically from __dir__.
    - Add normalize as a dt accessor method.
    - DataFrame and Series now have _constructor_expanddim property
      as overridable constructor for one higher dimensionality
      data. This should be used only when it is really needed
    - pd.lib.infer_dtype now returns 'bytes' in Python 3 where
    - We introduce a CategoricalIndex, a new type of index object
      that is useful for supporting indexing with duplicates. This
      is a container around a Categorical (introduced in v0.15.0)
      and allows efficient indexing and storage of an index with a
      large number of duplicated elements. Prior to 0.16.1,
      setting the index of a DataFrame/Series with a category
      dtype would convert this to regular object-based Index.
    - Series, DataFrames, and Panels now have a new method:
      pandas.DataFrame.sample. The method accepts a specific number
      of rows or columns to return, or a fraction of the total
      number or rows or columns. It also has options for sampling
      with or without replacement, for passing in a column for
      weights for non-uniform sampling, and for setting seed values
      to facilitate replication.
    - The following new methods are accesible via .str accessor to
      apply the function to each values.
      + capitalize()
      + swapcase()
      + normalize()
      + partition()
      + rpartition()
      + index()
      + rindex()
      + translate()
    - Added StringMethods (.str accessor) to Index
    - split now takes expand keyword to specify whether to expand
      dimensionality. return_type is deprecated.
    * API changes
    - When passing in an ax to df.plot( ..., ax=ax), the sharex
      kwarg will now default to False.
    - Add support for separating years and quarters using dashes,
      for example 2014-Q1.
    - pandas.DataFrame.assign now inserts new columns in
      alphabetical order. Previously the order was arbitrary.
    - By default, read_csv and read_table will now try to infer
      the compression type based on the file extension. Set
      compression=None to restore the previous behavior
      (no decompression).
    - The string representation of Index and its sub-classes have
      now been unified. These will show a single-line display if
      there are few values; a wrapped multi-line display for a lot
      of values (but less than display.max_seq_items; if lots of
      items > display.max_seq_items) will show a truncated display
      (the head and tail of the data). The formatting for
      MultiIndex is unchanges (a multi-line wrapped display). The
      display width responds to the option display.max_seq_items,
      which is defaulted to 100.
    * Deprecations
    - Series.str.split's return_type keyword was removed in favor
      of expand

    - Improved csv write performance with mixed dtypes, including
      datetimes by up to 5x

      scalar, which was not in the categories (e.g.
      Series(Categorical(list("abc"), ordered=True)) > "d". This
      returned False for all elements, but now raises a TypeError.
      Equality comparisons also now return False for == and True
      for !=.
    - Bug in DataFrame __setitem__ when right hand side is a
    - Bug in where when dtype is datetime64/timedelta64, but dtype
      of other is not

    - Bug in transform and filter when grouping on a categorical
    - Bug in transform when groups are equal in number and dtype to
      the input index
    - Google BigQuery connector now imports dependencies on a
      per-method basis.
    - Updated BigQuery connector to no longer use deprecated
    - Bug in subclassed DataFrame. It may not return the correct
      class, when slicing or subsetting it.
    - Bug in .median() where non-float null values are not handled

      convertible string is given
* Tue Mar 24 2015
  - update to version 0.16.0:
    * Highlights:
    - DataFrame.assign method
    - Series.to_coo/from_coo methods to interact with scipy.sparse
    - Backwards incompatible change to Timedelta to conform the .seconds
      attribute with datetime.timedelta
    - Changes to the .loc slicing API to conform with the behavior of .ix
    - Changes to the default for ordering in the Categorical constructor
    - Enhancement to the .str accessor to make string operations easier
    - The, pandas.sandbox.qtpandas and pandas.rpy
      modules are deprecated.  We refer users to external packages like
      seaborn, pandas-qt and rpy2 for similar or equivalent functionality
    * New features
    - Inspired by dplyr's mutate verb, DataFrame has a new assign method.
    - Added SparseSeries.to_coo and SparseSeries.from_coo methods for
      converting to and from scipy.sparse.coo_matrix instances.
    - Following new methods are accesible via .str accessor to apply the
      function to each values. This is intended to make it more consistent with
      standard methods on strings: isalnum(), isalpha(), isdigit(), isdigit(),
      isspace(), islower(), isupper(), istitle(), isnumeric(), isdecimal(),
      find(), rfind(), ljust(), rjust(), zfill()
    - Reindex now supports method='nearest' for frames or series with a
      monotonic increasing or decreasing index.
    - The read_excel() function's sheetname argument now accepts a list and
      None, to get multiple or all sheets respectively. If more than one sheet
      is specified, a dictionary is returned.
    - Allow Stata files to be read incrementally with an iterator; support for
      long strings in Stata files.
    - Paths beginning with ~ will now be expanded to begin with the user's home
    - Added time interval selection in get_data_yahoo.
    - Added Timestamp.to_datetime64() to complement Timedelta.to_timedelta64().
    - tseries.frequencies.to_offset() now accepts Timedelta as input.
    - Lag parameter was added to the autocorrelation method of Series, defaults
      to lag-1 autocorrelation.
    - Timedelta will now accept nanoseconds keyword in constructor.
    - SQL code now safely escapes table and column names.
    - Added auto-complete for Series.str.<tab>, Series.dt.<tab> and<tab>.
    - Index.get_indexer now supports method='pad' and method='backfill' even
      for any target array, not just monotonic targets.
    - Index.asof now works on all index types.
    - A verbose argument has been augmented in io.read_excel(), defaults to
      False. Set to True to print sheet names as they are parsed.
    - Added days_in_month (compatibility alias daysinmonth) property to
      Timestamp, DatetimeIndex, Period, PeriodIndex, and Series.dt.
    - Added decimal option in to_csv to provide formatting for non-'.' decimal
    - Added normalize option for Timestamp to normalized to midnight
    - Added example for DataFrame import to R using HDF5 file and rhdf5
    * Backwards incompatible API changes
    - In v0.16.0, we are restoring the API to match that of datetime.timedelta.
      Further, the component values are still available through the .components
      accessor. This affects the .seconds and .microseconds accessors, and
      removes the .hours, .minutes, .milliseconds accessors. These changes
      affect TimedeltaIndex and the Series .dt accessor as well.
    - The behavior of a small sub-set of edge cases for using .loc have
      changed. Furthermore we have improved the content of the error messages
      that are raised:
      + Slicing with .loc where the start and/or stop bound is not found in
      the index is now allowed; this previously would raise a KeyError. This
      makes the behavior the same as .ix in this case. This change is only
      for slicing, not when indexing with a single label.
      + Allow slicing with float-like values on an integer index for .ix.
      Previously this was only enabled for .loc:
      + Provide a useful exception for indexing with an invalid type for that
      index when using .loc. For example trying to use .loc on an index of
      type DatetimeIndex or PeriodIndex or TimedeltaIndex, with an integer
      (or a float).
    - In prior versions, Categoricals that had an unspecified ordering
      (meaning no ordered keyword was passed) were defaulted as ordered
      Categoricals. Going forward, the ordered keyword in the Categorical
      constructor will default to False. Ordering must now be explicit.
      Furthermore, previously you *could* change the ordered attribute of a
      Categorical by just setting the attribute, e.g. cat.ordered=True; This is
      now deprecated and you should use cat.as_ordered() or cat.as_unordered().
      These will by default return a **new** object and not modify the
      existing object.
    - Index.duplicated now returns np.array(dtype=bool) rather than
      Index(dtype=object) containing bool values.
    - DataFrame.to_json now returns accurate type serialisation for each column
      for frames of mixed dtype
    - DatetimeIndex, PeriodIndex and TimedeltaIndex.summary now output the same
    - TimedeltaIndex.freqstr now output the same string format as
    - Bar and horizontal bar plots no longer add a dashed line along the info
      axis. The prior style can be achieved with matplotlib's axhline or
      axvline methods.
    - Series accessors .dt, .cat and .str now raise AttributeError instead of
      TypeError if the series does not contain the appropriate type of data.
      This  follows Python's built-in exception hierarchy more closely and
      ensures that  tests like hasattr(s, 'cat') are consistent on both Python
      2 and 3.
    - Series now supports bitwise operation for integral types. Previously even
      if the input dtypes were integral, the output dtype was coerced to bool.
    - During division involving a Series or DataFrame, 0/0 and 0//0 now give
      np.nan instead of np.inf.
    - Series.values_counts and Series.describe for categorical data will now
      put NaN entries at the end.
    - Series.describe for categorical data will now give counts and frequencies
      of 0, not NaN, for unused categories
    - Due to a bug fix, looking up a partial string label with
      DatetimeIndex.asof now includes values that match the string, even if
      they are after the start of the partial string label. Old behavior:
    * Deprecations
    - The rplot trellis plotting interface is deprecated and will be removed
      in a future version. We refer to external packages like
      seaborn for similar but more refined functionality.
    - The pandas.sandbox.qtpandas interface is deprecated and will be removed
      in a future version.
      We refer users to the external package pandas-qt.
    - The pandas.rpy interface is deprecated and will be removed in a future
      Similar functionaility can be accessed thru the rpy2 project
    - Adding DatetimeIndex/PeriodIndex to another DatetimeIndex/PeriodIndex is
      being deprecated as a set-operation. This will be changed to a TypeError
      in a future version. .union() should be used for the union set operation.
    - Subtracting DatetimeIndex/PeriodIndex from another
      DatetimeIndex/PeriodIndex is being deprecated as a set-operation. This
      will be  changed to an actual numeric subtraction yielding a
      TimeDeltaIndex in a future  version. .difference() should be used for
      the differencing set operation.
    * Removal of prior version deprecations/changes
    - DataFrame.pivot_table and crosstab's rows and cols keyword arguments were
      removed in favor
      of index and columns
    - DataFrame.to_excel and DataFrame.to_csv cols keyword argument was removed
      in favor of columns
    - Removed convert_dummies in favor of get_dummies

      order. This is now consistent with the behavior for other dtypes in pandas.
    - Fixed bug on big endian platforms which produced incorrect results in
    - Bug in MultiIndex.has_duplicates when having many levels causes an

* Mon Jan 12 2015
  - update to version 0.15.2:
    * API changes:
    - Indexing in MultiIndex beyond lex-sort depth is now supported,
      though a lexically sorted index will have a better
      performance. (GH2646)
    - Bug in unique of Series with category dtype, which returned all
      categories regardless whether they were "used" or not (see
      GH8559 for the discussion). Previous behaviour was to return all
    - Series.all and Series.any now support the level and skipna
      parameters. Series.all, Series.any, Index.all, and Index.any no
      longer support the out and keepdims parameters, which existed
      for compatibility with ndarray. Various index types no longer
      support the all and any aggregation functions and will now raise
      TypeError. (GH8302).
    - Allow equality comparisons of Series with a categorical dtype
      and object dtype; previously these would raise TypeError
    - Bug in NDFrame: conflicting attribute/column names now behave
      consistently between getting and setting. Previously, when both
      a column and attribute named y existed, data.y would return the
      attribute, while data.y = z would update the column (GH8994)
    - Timestamp('now') is now equivalent to in that it
      returns the local time rather than UTC. Also, Timestamp('today')
      is now equivalent to and both have tz as a
      possible argument. (GH9000)
    - Fix negative step support for label-based slices (GH8753)
    * Enhancements:
    - Added ability to export Categorical data to Stata (GH8633). See
      here for limitations of categorical variables exported to Stata
      data files.
    - Added flag order_categoricals to StataReader and read_stata to
      select whether to order imported categorical data (GH8836). See
      here for more information on importing categorical variables
      from Stata data files.
    - Added ability to export Categorical data to to/from HDF5
      (GH7621). Queries work the same as if it was an object
      array. However, the category dtyped data is stored in a more
      efficient manner. See here for an example and caveats
      w.r.t. prior versions of pandas.
    - Added support for searchsorted() on Categorical class (GH8420).
    - Added the ability to specify the SQL type of columns when
      writing a DataFrame to a database (GH8778). For example,
      specifying to use the sqlalchemy String type instead of the
      default Text type for string columns.
    - Series.all and Series.any now support the level and skipna
      parameters (GH8302).
    - Panel now supports the all and any aggregation
      functions. (GH8302).
    - Added support for utcfromtimestamp(), fromtimestamp(), and
      combine() on Timestamp class (GH5351).
    - Added Google Analytics ( basic documentation
    - Timedelta arithmetic returns NotImplemented in unknown cases,
      allowing extensions by custom classes (GH8813).
    - Timedelta now supports arithemtic with numpy.ndarray objects of
      the appropriate dtype (numpy 1.8 or newer only) (GH8884).
    - Added Timedelta.to_timedelta64() method to the public API
    - Added gbq.generate_bq_schema() function to the gbq module
    - Series now works with map objects the same way as generators
    - Added context manager to HDFStore for automatic closing
    - to_datetime gains an exact keyword to allow for a format to not
      require an exact match for a provided format string (if its
      False). exact defaults to True (meaning that exact matching is
      still the default) (GH8904)
    - Added axvlines boolean option to parallel_coordinates plot
      function, determines whether vertical lines will be printed,
      default is True
    - Added ability to read table footers to read_html (GH8552).
    - to_sql now infers datatypes of non-NA values for columns that
      contain NA values and have dtype object (GH8778).
    * Performance:
    - Reduce memory usage when skiprows is an integer in read_csv
    - Performance boost for to_datetime conversions with a passed
      format=, and the exact=False (GH8904)
    * Bug fixes:
    - Bug in concat of Series with category dtype which were coercing
      to object. (GH8641)
    - Bug in Timestamp-Timestamp not returning a Timedelta type and
      datelike-datelike ops with timezones (GH8865)
    - Made consistent a timezone mismatch exception (either tz
      operated with None or incompatible timezone), will now return
      TypeError rather than ValueError (a couple of edge cases only),
    - Bug in using a pd.Grouper(key=...) with no level/axis or level
      only (GH8795, GH8866)
    - Report a TypeError when invalid/no paramaters are passed in a
      groupby (GH8015)
    - Bug in packaging pandas with py2app/cx_Freeze (GH8602, GH8831)
    - Bug in groupby signatures that didn’t include *args or **kwargs
    - now raises RemoteDataError when no expiry dates
      are available from Yahoo and when it receives no data from Yahoo
      (GH8761), (GH8783).
    - Unclear error message in csv parsing when passing dtype and
      names and the parsed data is a different data type (GH8833)
    - Bug in slicing a multi-index with an empty list and at least one
      boolean indexer (GH8781)
    - now raises RemoteDataError when no expiry dates
      are available from Yahoo (GH8761).
    - Timedelta kwargs may now be numpy ints and floats (GH8757).
    - Fixed several outstanding bugs for Timedelta arithmetic and
      comparisons (GH8813, GH5963, GH5436).
    - sql_schema now generates dialect appropriate CREATE TABLE
      statements (GH8697)
    - slice string method now takes step into account (GH8754)
    - Bug in BlockManager where setting values with different type
      would break block integrity (GH8850)
    - Bug in DatetimeIndex when using time object as key (GH8667)
    - Bug in merge where how='left' and sort=False would not preserve
      left frame order (GH7331)
    - Bug in MultiIndex.reindex where reindexing at level would not
      reorder labels (GH4088)
    - Bug in certain operations with dateutil timezones, manifesting
      with dateutil 2.3 (GH8639)
    - Regression in DatetimeIndex iteration with a Fixed/Local offset
      timezone (GH8890)
    - Bug in to_datetime when parsing a nanoseconds using the %f
      format (GH8989)
    - now raises RemoteDataError when no expiry dates
      are available from Yahoo and when it receives no data from Yahoo
      (GH8761), (GH8783).
    - Fix: The font size was only set on x axis if vertical or the y
      axis if horizontal. (GH8765)
    - Fixed division by 0 when reading big csv files in python 3
    - Bug in outputing a Multindex with to_html,index=False which
      would add an extra column (GH8452)
    - Imported categorical variables from Stata files retain the
      ordinal information in the underlying data (GH8836).
    - Defined .size attribute across NDFrame objects to provide compat
      with numpy >= 1.9.1; buggy with np.array_split (GH8846)
    - Skip testing of histogram plots for matplotlib <= 1.2 (GH8648).
    - Bug where get_data_google returned object dtypes (GH3995)
    - Bug in DataFrame.stack(..., dropna=False) when the DataFrame’s
      columns is a MultiIndex whose labels do not reference all its
      levels. (GH8844)
    - Bug in that Option context applied on __enter__ (GH8514)
    - Bug in resample that causes a ValueError when resampling across
      multiple days and the last offset is not calculated from the
      start of the range (GH8683)
    - Bug where DataFrame.plot(kind='scatter') fails when checking if
      an np.array is in the DataFrame (GH8852)
    - Bug in pd.infer_freq/DataFrame.inferred_freq that prevented
      proper sub-daily frequency inference when the index contained
      DST days (GH8772).
    - Bug where index name was still used when plotting a series with
      use_index=False (GH8558).
    - Bugs when trying to stack multiple columns, when some (or all)
      of the level names are numbers (GH8584).
    - Bug in MultiIndex where __contains__ returns wrong result if
      index is not lexically sorted or unique (GH7724)
    - BUG CSV: fix problem with trailing whitespace in skipped rows,
      (GH8679), (GH8661), (GH8983)

      argument was a numpy array scalar (e.g. np.int64) (:issue:`8658`)
    - Bug in Panel indexing with a list-like (:issue:`8710`)
    - Compat issue is ``DataFrame.dtypes`` when
      ``options.mode.use_inf_as_null`` is True (:issue:`8722`)
    - Bug in ``read_csv``, ``dialect`` parameter would not take a string
      (:issue: `8703`)
    - Bug in slicing a multi-index level with an empty-list (:issue:`8737`)
    - Bug in numeric index operations of add/sub with Float/Index Index with
      numpy arrays (:issue:`8608`)
    - Bug in setitem with empty indexer and unwanted coercion of dtypes
    - Bug in ix/loc block splitting on setitem (manifests with integer-like
      dtypes, e.g. datetime64) (:issue:`8607`)
    - Bug when doing label based indexing with integers not found in the index
      for non-unique but monotonic indexes (:issue:`8680`).
    - Bug when indexing a Float64Index with ``np.nan`` on numpy 1.7
    - Fix ``shape`` attribute for ``MultiIndex`` (:issue:`8609`)
    - Bug in ``GroupBy`` where a name conflict between the grouper and columns
      would break ``groupby`` operations (:issue:`7115`, :issue:`8112`)
    - Fixed a bug where plotting a column ``y`` and specifying a label would
      mutate the index name of the original DataFrame (:issue:`8494`)
    - Fix regression in plotting of a DatetimeIndex directly with matplotlib
    - Bug in ``date_range`` where partially-specified dates would incorporate
      current date (:issue:`6961`)
    - Bug in Setting by indexer to a scalar value with a mixed-dtype `Panel4d`
      was failing (:issue:`8702`)
    - Bug where ``DataReader``'s would fail if one of the symbols passed was
      invalid.  Now returns data for valid symbols and np.nan for invalid
    - Bug in ``get_quote_yahoo`` that wouldn't allow non-float return values

  - Update to 0.15.0, highlights:
    - Drop support for numpy < 1.7.0
    - The Categorical type was integrated as a first-class
      pandas type
    - New scalar type Timedelta, and a new index type TimedeltaIndex
    - New DataFrame default display for to
      include memory usage
    - New datetimelike properties accessor .dt for Series
    - Split indexing documentation into Indexing and Selecting Data and
      MultiIndex / Advanced Indexing
    - Split out string methods documentation into Working with Text Data
    - read_csv will now by default ignore blank lines when parsing
    - API change in using Indexes in set operations
    - Internal refactoring of the Index class to no longer
      sub-class ndarray
    - dropping support for PyTables less than version 3.0.0,
      and numexpr less than version 2.1
  - Update minimum dependency versions of
    python-numpy, python-tables, and python-numexpr
