Overview of changes leading to 2.7.4
Sunday, December 27, 2020
====================================
- Fix missing --enable-introspection configure option from previous release
tarball.
- Documentation updates.
Overview of changes leading to 2.7.3
Wednesday, December 23, 2020
====================================
- Update USE shaper to 2020-08-13 specification, and other improvements.
- Don’t disable liga feature in myanmar shaper, to match Uniscribe.
- Improvements to language and script tags handling.
- Update language system tag registry to OpenType 1.8.4
- Support for serializing and deserializing Unicode buffers. Serialized buffers
are now delimited with `<>` or `[]` based on whether it is a Unicode or
glyphs buffer.
- Increase buffer work limits to handle fonts with many complex lookups.
- Handle more shaping operations in trace output.
- Memory access fixes.
- More OOM fixes.
- Improved documentation.
- Build system improvements.
- New API:
+hb_buffer_has_positions()
+hb_buffer_serialize()
+hb_buffer_serialize_unicode()
+hb_buffer_deserialize_unicode()

* Data type for holding HarfBuzz's clustering behavior options. The cluster level
* dictates one aspect of how HarfBuzz will treat non-base characters
* during shaping.
*
* In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES, non-base
* characters are merged into the cluster of the base character that precedes them.
*
* In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS, non-base characters are initially
* assigned their own cluster values, which are not merged into preceding base
* clusters. This allows HarfBuzz to perform additional operations like reorder
* sequences of adjacent marks.
*
* @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES is the default, because it maintains
* backward compatibility with older versions of HarfBuzz. New client programs that
* do not need to maintain such backward compatibility are recommended to use
* @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS instead of the default.
