v.1.4.0

• MAJOR performance gains in the .to_js_literal() method. Implementation seems to
  improve performance by 50 - 90%.

• SIGNIFICANT performance gains in the .to_json() method. Implementation seems to
  improve performance by 30 - 90%.

• ENHANCEMENT: Significantly simplified use of the .from_pandas() method to support:

  • creation of multiple series from one DataFrame in one method call
  • creation of series without needing to specify a full property map
  • support for creating series by DataFrame row, rather than just by DataFrame column

• ENHANCEMENT: Added the .from_pandas_in_rows() method to support creation of
  charts and series from simple two-dimensional DataFrames laid out in rows.

• ENHANCEMENT: Added one-shot chart creation and rendering from Series objects.

• ENHANCEMENT: Added one-shot chart creation using series and data/series_type keywords.

• ENHANCEMENT: Added .convert_to() convenience method to Series objects.

• ENHANCEMENT: Added CallbackFunction.from_python() method which converts a Python function
  to its JavaScript equivalent using generative AI, with support for both OpenAI and Anthropic.

• BUGFIX: Fixed instability issues in Jupyter Notebooks, both when operating as a Notebook (outside of
  Jupyter Lab) and when saved to a static HTML file.

v.1.3.0

• ENHANCEMENT: Modified the way that data points are serialized to JavaScript literal objects. Now, they are serialized to a JavaScript array if their configured properties are those that Highcharts (JS) supports in JavaScript array notation. Otherwise, the code falls back to serialize the data point as a JavaScript object literal. This change is intended to improve performance and reduce the size of the serialized data. (#32 )
• ENHANCEMENT: Added __repr__() method for Highcharts Core for Python classes.
• ENHANCEMENT: Added __str__() method with special handling for difficult-to-read classes.
• ENHANCEMENT: Added Chart.get_script_tags() to retrieve Javascript <script> tags.
• ENHANCEMENT: Added utility_functions.to_snake_case() function.
• BUGFIX: Fixed incorrect serialization of datetime and Pandas Timestamp objects in .to_dict() and .to_json().
• BUGFIX: Fixed incorrect serialization of EnforcedNull in .to_dict() and .to_json().

v.1.2.3

• BUGFIX: Fixed reference bug in serialization of GanttData instances with timezone-naive datetime instances in start and end.

v.1.2.2

• BUGFIX: Fixed support for serialization of GanttData instances with timezone-naive datetime instances in start and end``. Closes #29.
• DOCS: Fixed broken links in documentation to options.series.gantt.GanttSeries and options.series.data.gantt.GanttData. Closes #28.

v.1.2.1

• BUGFIX: Fixed incorrect datetime serialization to seconds from Unix epoch. Now serializing to JS-compatible milliseconds from Unix epoch.
