Important
Starting from v0.3.0, the transition from libjq Rust binding j9 to jq clone jaq was made.
This change eliminated the need to manage C-related dependencies that include external tools like autoconf, thus simplifying the build process. However, please note that some filters are not yet supported by jaq. For more details, refer to GitHub issue #24.
Please continue to provide feedback regarding this transition.
