Hot patched language packs are a new way of delivering language support in AutoCAD 2023. Unlike traditional language packs, which require a separate installation, hot patched language packs can be applied dynamically without restarting the software. This approach allows users to switch between languages instantly, without the need for administrative privileges. The hot patched language packs are essentially incremental updates that modify the existing software installation, making it possible to add or remove languages on the fly.
