libchewing 0.7.0 Released: 2024-04-07

What’s New in libchewing 0.7.0

This is the first beta release of the Rust rewrite. The library has been tested with the AFL++ fuzzer and most of the obvious bugs have been fixed so it should not crash for normal use. Now we invite power users to daily drive the beta release in order to find more subtle bugs.

The Rust rewrite is ABI compatible with previous releases. The most notable difference with the C version includes a new portable dictionary format that can be used both as system dictionary and user dictionary. Users with existing user phrase dictionary will be automatically migrated. Old files will be backed up automatically. With these change we will be able to support dictionary sharing and loading multiple dictionaries in future releases.
