NanaZip 6.0 Final (6.0.1630.0)

I'm excited to announce that we've released the NanaZip 6.0 Final, now available for download.

Starting with NanaZip 6.0, the development team will adopt the new release-tag rule. Read NanaZip/Documents/Versioning.md at main · M2Team/NanaZip for more information.

I will submit 6.0 stable to the Microsoft Store and wait for Microsoft's verification on February 18, 2026, because I hope the NanaZip 6.0 stable build may be 1632. That number can play many puns: Hex is 0x660, decimal digits can express all factors for (6, a.k.a. 1, 2, 3, 6). (Beauty of mathematics.)

If this release has no big issues, it will be recompiled as the stable version.

This release also adjusts the main window UI layout.
