think the biggest remaining is the agg PR).

Subject: [Pandas-dev] Deprecation of using a dict in groupby().agg({...}) to
 rename resulting columns
Message-ID: <CALQtMBbOZ0mZDCsVcfyXMwfuFEmCLGDKkB9_aqGsvhhPT9_csA@mail.gmail.com>

Hi all,

As a heads up, we are deprecating the use of a dictionary in the agg method
on groupby/resample/rolling objects.

Basic example:

In [1]: df = pd.DataFrame({'A': [1, 1, 1, 2, 2],
   ...:                    'B': range(5),
   ...:                    'C':range(5)})

In [3]: df.groupby('A').B.agg({'foo': 'count'})
Out[3]:
   foo
A
1    3
2    2

The above will be deprecated (and removed in a future version).

The documentation added in https://github.com/pandas-dev/pandas/pull/15931
gives a more detailed explanation of the reasoning, but basically it is to
clean up the API: now you can use dicts both to specify a aggregation
function for a specific column (for dataframes) as to rename the result
(series, or dataframes with nested dict), which is a confusing double use
of dicts.

The PR will be merged shortly, but the 0.20 release is still a few weeks
off, so certainly still time to give feedback. Which is certainly welcome!

Regards,
Joris

Hi,

I'm pleased to announce the availability of the first release candidate of
pandas 0.20.0. *Please try this RC and report any issues on the pandas
issue tracker <https://github.com/pandas-dev/pandas/issues/>. We will be
releasing officially in 1-2 weeks.*

RELEASE CANDIDATE 1

This is a major release from 0.19.2 and includes a small number of API
changes, several new features,
enhancements, and performance improvements along with a large number of bug
fixes.

Highlights include:

   - new .agg() API for Series/DataFrame similar to the
   groupby-rolling-resample API's, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-agg>
   - Integration with the feather-format, including a new top-level
   pd.read_feather() and DataFrame.to_feather() method, see here
   <http://pandas-docs.github.io/pandas-docs-travis/io.html#io-feather>
   - The .ix indexer has been deprecated, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-api-breaking-deprecate-ix>
   - Panel has been deprecated, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-api-breaking-deprecate-panel>
   - Addition of an IntervalIndex and Interval scalar type, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-intervalindex>
   - Improved user API when accessing levels in .groupby(), see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-groupby-access>
   - Improved support for UInt64 dtypes, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-uint64-support>
   - A new orient for JSON serialization, orient='table', that uses the
   Table Schema spec, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-table-schema>
   - Experimental support for exporting DataFrame.style formats to Excel,
   see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-enhancements-style-excel>
   - Window Binary Corr/Cov operations now return a MultiIndexed
DataFrame rather
   than a Panel, as Panel is now deprecated, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-api-breaking-rolling-pairwise>
   - Support for S3 handling now uses s3fs, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-api-breaking-s3>
   - Google BigQuery support now uses the pandas-gbq library, see here
   <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0200-api-breaking-gbq>
   - Switched the test framework to use pytest

See the Whatsnew
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html> file for
more information. Please report any issues here
<https://github.com/pydata/pandas/issues/>.

The release candidate can be installed with conda from our development
channel (builds for osx-64, linux-64 and win-64 for Python 2.7, Python 3.5,
and Python 3.6 are all available):

conda install -c pandas pandas=0.20.0rc1

Or via PyPI

pip install --upgrade pip setuptools
pip install --pre --upgrade --upgrade-strategy=only-if-needed pandas
