# Revision history for Balkón
## 0.3.0.0 -- TBD
* Limited support for bidirectional text (LTR and RTL in the same paragraph).
* The paragraph direction is assumed to be LTR.
This will be configurable in a future interface.
* Only strong directional characters are used to determine text direction.
* The direction of weak directional characters and neutral characters is
determined by the nearest preceding strong directional character, or if
none is found, the nearest following strong directional character.
* Explicit bidirectional formatting characters are ignored.
* Exposed functions to allow verification of correct input text slicing:
`paragraphSpanBounds`, `paragraphSpanTexts`, and `paragraphText`.
## 0.2.1.0 -- 2023-04-04
* Added pagination.
## 0.2.0.0 -- 2023-03-28
* Added support for forced (hard) line breaks in the input text.
* Now also trimming white space at the beginning of lines.
* Internally, language tags will be cut at the first invalid character before
being passed to ICU.
* Tests will generate output in "shaped runs" format which can be passed to
a text rendering application.
## 0.1.0.0 -- 2023-03-13
* Text shaping using HarfBuzz.
* Breaking text on line and character boundaries using the International
Components for Unicode (ICU) library.
* Trimming white space at the end of lines.
* Calculation of containing block bounds and fragment bounds.
* Support for plain text (single font and line height) in one horizontal
direction (LTR or RTL).
* Input can be divided into spans. This division will be preserved in the
output.
* Each span can use a different language for text shaping and line breaking.
