- The `include` block now supports `with context` and `without context`
modifiers but they are ignored. This is mostly helpful to render some
Jinja2 templates that depend on this functionality. (288)
- Added tests `true`, `false`, `filter`, `test` and filters
`pprint` and `unique`. (287)
- Added support for indexing into strings. (149)
- Added `Error::detail` which returns the detail help string. (289)
- Added `Error::template_source` and `Error::range` to better support
rendering of errors outside of the built-in debug printing. (286)
