# Rust Engine Changelog

Engine changes also reach npm users through `@atlowchemi/webfont-generator`, whose version
is synchronized with the engine. See the [npm Adapter Changelog](./changelog) for Node.js
integration changes, or [engine GitHub releases](https://github.com/atlowChemi/vite-svg-2-webfont/releases?q=webfont-engine-v).

## [0.11.0](https://github.com/atlowChemi/vite-svg-2-webfont/compare/webfont-engine-v0.10.0...webfont-engine-v0.11.0) (2026-10-28)

### ⚠ BREAKING CHANGES

* **webfont-generator:** CLI inputs must be explicit paths. Bare names such as `icons`, `icons/` or `plus.svg` are rejected; write `./icons`, `./icons/` or `./plus.svg` instead. `clear-cache` and `help` are subcommands.

## \[0.7.0]

Changes to the Rust engine and CLI are recorded here starting with the workspace extraction.
Earlier releases are documented in the [shared generator changelog](https://github.com/atlowChemi/vite-svg-2-webfont/blob/main/packages/webfont-generator/CHANGELOG.md).

The engine has its own GitHub releases under `webfont-engine-v*`; its crates.io name remains
`webfont-generator`. Engine and npm adapter versions remain synchronized.
