Earthly's latest updates introduce several enhancements and fixes, focusing on improving the Docker build process. Key changes include the addition of new Bash autocompletion and experimental Docker operations that mitigate disk performance issues by using the new WITH DOCKER syntax. The release also provides support for building dockerfiles generated inside Earthly targets and includes the COPY --chown feature. Additionally, several bug fixes have been implemented, such as resolving issues with the EARTHLY_SECRETS environment variable and ensuring failure output is consistently printed. Users are encouraged to upgrade from version 0.3.x using the "earth prune --reset" command.
