v0.4.1

Bugfixes

• Fix a crash in TimeseriesList#to_dataframe().

v0.4

Improve pandas integration with more utility methods.

Improvements

• Page objects are now immutable (for curve and place search responses).
• Add Series.set_name() to let users set a custom name for time series' and period-based series'.
• Add TimeseriesList with a to_dataframe() method for converting a list of time series to a pandas data frame. It subclasses Python's built-in list and overrides its methods with extra validations.
• Add PeriodseriesList. Similar to TimeseriesList, it subclasses Python's list. It has two methods: (1) to_timeseries() which converts this list to a TimeseriesList, and (2) to_dataframe(frequency) which converts this list to a data frame.
• Add Periodseries#to_dataframe(frequency). Previously, you would have to first convert the period-based series to a time series and then call to_dataframe.
• Update headers in pandas data frames.
• Add OHLCList#to_dataframe() for converting OHLC data to a data frame.
• Update documentation where applicable with a short description on how to convert time series, period-based series and OHLC data to data frames.
• Add own chapter on how to convert data to pandas.DataFrame.
• Add own chapter on packages and where to find the different classes and enumerators.

Breaking change

With better pandas integration, we changed column headers for data frames. As of v0.4, data frames have three column header levels for time series data:

1. Curve name
2. Instance or contract
3. Scenario (ensemble)

We did this to better describe the data when converted from time series' to pandas data frames. Refer to the chapter on pandas integration for more details.

v0.3

Introducing support for OHLC data (open, high, low, close).

Improvements

• Implement operations in the OHLC API: load(), latest(), load_delivery_as_timeseries(), and load_front_as_timeseries()
• Add data and metadata classes for OHLC: OHLCField, ContractPeriod, Product, OHLC, OHLCList, and Contract.
• Add member Series#contract, which is a reference to a set by the load_*_as_timeseries()-operations.
• Add documentation for OHLC.
• Add new curve data type: DataType.SCENARIO

Bugfixes

• Fix runtime error in Series#name() (Series is superclass of Timeseries and Periodseries).
• ValidationError exceptions occuring on the server-side didn't include which parameter that failed due to a bug in the JSON error message parser.

v0.2

A small release with two improvements.

Improvements

• Add Periodseries#print() method.
• Increase 1-10 days-ahead constraints for relative queries to 0-10000.

v0.1

The first public release of Energy Quantified's Python client. Woho!

Improvements

• Add utilities for working with date-times, frequencies, time-zones and
  resolutions.
• Add metadata classes for areas, curves, instances, places and more.
• Add classes for time series and period-based series.
• Add wrapper around requests with rate-limiting, auto-retry on failure
  and authentication.
• Implement APIs for metadata, timeseries, instances, periods and
  period-instances.
• Add support for timeseries-to-pandas conversion.
• Add meaningful exceptions.
• Add a few examples to the git repo.
• Write tons of documentation.

Dependencies

• Add pytz, tzlocal, python-dateutil, requests.
• Not adding pandas, as it is optional.

Bugfixes

• (None in this release, but probably introduced some!)
