8B has been released in version v0.3.1 - shortly after version 0.3.0.
The Rust-based tool creates and edits controller profiles for 8BitDo devices directly over USB on Linux. We last covered version 0.2.1.
New in v0.3.0 is support for internationalization, including a Brazilian Portuguese (PT-BR) translation. The v0.3.1 update fixes that translation.
Changes in version 0.3.0:
- Support for internationalization
- PT-BR translation added
Changes in version 0.3.1:
Minor patch to fix the PT-BR translation
