 ## v0.17.0 Characinae - 2021-10-09
 This is a minor version update. As mentioned in `0.5.0` logs, the new version system would merge the old major and minor version numbers into new minor version numbers, thus as the 17th minor version update since NOJ `0.1.0`, this version would be numbered as major version `0`, minor version `17`, build pack `0` and patch number `0`.
