An official roadmap for OpenWrt 25.x/26.x does not exist but these features are likely (hopefully) incorporated:
- LTS kernel 6.12 https://github.com/openwrt/openwrt/issues/16569
- Wi-Fi 7 improvements
- switch from opkg to Alpine Package Keeper (APK)
https://github.com/openwrt/packages/issues/23706
The future is now: opkg vs apk
