• pd.date_time now has experimental supported for time-related columns
• plots now support the official IPCC scenario color palatte
• native support for putting legends outside of plot axes
• dataframes can now be initialized with default values, making reading raw datasets easier

• #228 Update development environment creation instructions and make pandas requirement more specific
• #219 Add ability to query metadata from iiasa data sources
• #214 Tidy up requirements specifications a little
• #213 Add support for IPCC colors, see the new tutorial "Using IPCC Color Palattes"
• #212 Now natively support reading R-style data frames with year columns like "X2015"
• #207 Add a aggregate_region() function to sum a variable from subregions and add components that are only defined at the region level
• #202 Extend the df.rename() function with a check_duplicates (default True) validation option
• #201 Added native support for legends outside of plots with pyam.plotting.OUTSIDE_LEGEND with a tutorial
• #200 Bugfix when providing cmap and color arguments to plotting functions
• #199 Initializing an IamDataFrame accepts kwargs to fill or create from the data any missing required columns
• #198 Update stack plot functionality and add aggregation tutorial. Also adds a copy method to IamDataFrame.
• #197 Added a normalize function that normalizes all data in a data frame to a specific time period.
• #195 Fix filtering for time, day and hour to use generic pattern_match() (if such a column exists) in 'year'-formmatted IamDataFrames
• #192 Extend utils.find_depth() to optionally return depth (as list of ints) rather than assert level tests
• #190 Add concat() function
• #189 Fix over-zealous dropna() in scatter()
• #186 Fix over-zealous dropna() in line_plot(), rework as_pandas() to (optionally) discover meta columns to be joined
• #178 Add a kwarg append to the function rename(), change behaviour of mapping to only apply to data where all given columns are matched
• #177 Modified formatting of time column on init to allow subclasses to avoid pandas limitation (https://stackoverflow.com/a/37226672)
• #176 Corrected title setting operation in line_plot function
• #175 Update link to tutorial in readme.md
• #174 Add a function difference() to compare two IamDataFrames
• #171 Fix a bug when reading from an ixmp.TimeSeries object, refactor to mitigate circular dependency
• #162 Add a function to sum and append timeseries components to an aggregate variable
• #152 Fix bug where scatter plots did not work with property metadata when using two variables (#136, #152)
• #151 Fix bug where excel files were not being written on Windows and MacOSX (#149)
• #145 Support full semantic and VCS-style versioning with versioneer
• #132 support time columns using the datetime format and additional str columns in data
