I'm excited to announce that we've released NanaZip 6.5, now available for download.

I think we should have a new baseline and a new version tag rule because there are too many update numbers (something like Update 8) in 6.0, which looks more like a baka (the romaji of バカ, or idiot in English). Read https://github.com/M2Team/NanaZip/blob/main/Documents/Versioning.md#release-tags for more information about the adjusted version tag rule.

Note: Read [NanaZip Technical Focus from Kenji Mouri](https://github.com/M2Team/NanaZip/issues/913) to clarify some future directions of NanaZip.
