0.11.1

This release adds a new shape-run-cache feature that, when enabled, will cache the results of shaping operations to significantly improve performance, at the cost of increased memory usage. Make sure to trim the cache with the ShapeRunCache::trim function regularly. Also make sure to set keep_ages to a large enough value that entries are not removed too early, as minor changes in the source text can switch between active entries (such as adding or removing a space in the middle of a word).

Added

• Add shape-run-cache feature, that can significantly improve shaping performance

Removed

• Remove editor-libcosmic, see cosmic-edit instead

Links

• Crate on crates.io

Added

• Add function to set metrics and size simultaneously
• Cache rustybuzz shape plans
