Docassemble

Added
- Playground "Variables, etc." for the Word task pane.
Changed
- It is no longer necessary to remove curly quotes from .docx Jinja2
code. They will be converted to straight quotes before processing.
Fixed
- Google Maps JavaScript was loading synchronously, which slowed down
loading.
- A `choices` list could not contain a list of numeric, boolean,
or `NoneType` values.
- `DAStaticFile`s could not be inserted into .docx templates.

Added
- Integration between Microsoft OneDrive and the Playground.
- The `debug` directive inside `features`.
Changed
- Upgraded Font Awesome to 5.3.1.

Added
- The `update references` setting on `attachment`s.

Added
- The `redact()` function and `redact` option on `attachment`s.
Changed
- The `template` and `table` blocks now become `DALazyTemplate`
objects rather than `DATemplate` objects. Their contents are
evaluated at the time they are reduced to text, not at the time they
are created.
Fixed
- Problem with `currency()` and other functions when used from a `docx
template file` where undefined variables did not raise exceptions.
- The `create_new_interview()` function caused unnecessary 4 second delay.
- Users with `user` privileges could not access API key management.
- The `interview_url()` function was returning a URL based on how the
current request was made, rather than the actual URL for getting to
an interview.

Fixed
- Problem with `DATemplate` variables with string indices.

Added
- The `show progress bar percentage` feature.
Changed
- The `background_response()` function can be called using
`background_response('refresh')` to refresh the user's screen.
