We technically removed the last C++ code from the core project in January 2024 (~a year ago), the last C++ code altogether (a test helper) in June 2024 (six months ago). We only decided to push out a release now because we've added enough new features (not counting the rewrite as a feature) to warrant a release.

But at the same time, someone could argue that the current codebase is still far from being fully idiomatic rust, there are various C++-isms ranging from the use of UTF-32 (historical from the nature of std::wchar/std::wstring under *nix) to still passing around file descriptors rather than rust `File` objects (that will take a lot of rearchitecting to make mut-safe).

Ultimately, a project is never "done" and we're not being paid at all let alone contingent upon completion of the port, so there's no real use in saying it took precisely this long or that long. We're releasing now because we want to, but I wouldn't tie the release cadence with the port timespan.
