0.6.19 (2021-05-17)¶
- Add shapes.add_ole_object(), allowing arbitrary Excel or other binary file to be embedded as a shape on a slide. The OLE object is represented as an icon.
0.6.18 (2019-05-02)¶
.text property getters encode line-break as a vertical-tab (VT, ‘v’, ASCII 11/x0B). This is consistent with PowerPoint’s copy/paste behavior and allows like-breaks (soft carriage-return) to be distinguished from paragraph boundary. Previously, a line-break was encoded as a newline (‘n’) and was not distinguishable from a paragraph boundary.
.text properties include Shape.text, _Cell.text, TextFrame.text, _Paragraph.text and _Run.text.
.text property setters accept vertical-tab character and place a line-break element in that location. All other control characters other than horizontal-tab (‘t’) and newline (‘n’) in range x00-x1F are accepted and escaped with plain-text like “_x001B” for ESC (ASCII 27).
Previously a control character other than tab or newline in an assigned string would trigger an exception related to invalid XML character.

BACKWARD INCOMPATIBILITIES:
Some changes were made to the boilerplate XML used to create new charts. This was done to more closely adhere to the settings PowerPoint uses when creating a chart using the UI. This may result in some appearance changes in charts after upgrading. In particular:
- Chart.has_legend now defaults to True for Line charts.
- Plot.vary_by_categories now defaults to False for Line charts.

0.5.0 (2014-09-13)¶
- Add support for creating and manipulating bar, column, line, and pie charts
- Major refactoring of XML layer (oxml)
- Rationalized graphical object shape access Note backward incompatibilities below
BACKWARD INCOMPATIBILITIES:
A table is no longer treated as a shape. Rather it is a graphical object contained in a GraphicFrame shape, as are Chart and SmartArt objects.
Example:
table = shapes.add_table(...)
# becomes
graphic_frame = shapes.add_table(...)
table = graphic_frame.table
# or
table = shapes.add_table(...).table
As the enclosing shape, the id, name, shape type, position, and size are attributes of the enclosing GraphicFrame object.
The contents of a GraphicFrame shape can be identified using three available properties on a shape: has_table, has_chart, and has_smart_art. The enclosed graphical object is obtained using the properties GraphicFrame.table and GraphicFrame.chart. SmartArt is not yet supported. Accessing one of these properties on a GraphicFrame not containing the corresponding object raises an exception.
