   * xdp-tools: update from 1.4.3 to 1.6.3


Upgrading to 25.12.3
=====================

Upgrading from 24.10 to 25.12 should be transparent on most devices, as 
most configuration data has either remained the same or will be 
translated correctly on first boot by the package init scripts.
For upgrades within the OpenWrt 25.12 stable series, [Attended 
Sysupgrade](https://openwrt.org/docs/guide-user/installation/attended.sysupgrade) 
is also supported, which allows preserving the installed packages.

  * Sysupgrade from 23.05 or earlier to 25.12 is not officially supported.

  * Cron log level was fixed in busybox. 
`system. at system[0].cronloglevel` should be set to `7` for normal 
logging. `7` is the default now. If this option is not set, the default 
is used and no manual action is needed. 
https://github.com/openwrt/openwrt/commit/fc0c518a88e68d3deef04bec73b33d35186d6546

  * Bananapi BPI-R4: Interface `eth1` was renamed to `sfp-lan` or 
`lan4`, and interface `eth2` was renamed to `sfp-wan` to match the 
labels. You have to upgrade without saving the configuration. 
https://github.com/openwrt/openwrt/commit/cd8dcfef378044a1687adfa3738f01f9a9622baf

  * **TP-Link RE355 v1, RE450 v1 and RE450 v2:** The partition layout 
and block size changed in this release to fix configuration loss on 
sysupgrade. Users upgrading from OpenWrt 25.12.0 or earlier must use 
`sysupgrade -F` to force the upgrade. The image must not exceed 5.875 MB 
(6016 KiB).

  * **Meraki MX60:** Direct sysupgrade to 25.12.3 is not possible 
without manual preparation ? `meraki_loadaddr` must be changed before 
upgrading, as the default value is insufficient to boot OpenWrt 25.12+. 
See the device wiki page for instructions.


Known issues
============

   * Zyxel EX5601-T0: the WAN interface was renamed from `eth1` to `wan` 
? check and update your network configuration after upgrading.
   * Pixel 10 phones have problems connecting to WPA3-protected WiFi 6 
APs. https://github.com/openwrt/openwrt/issues/21486
   * 802.11r Fast Transition (FT) causes connection problems with some 
WiFi clients when WPA3 is used. 
https://github.com/openwrt/openwrt/issues/22200
   * SQM CAKE MQ (`cake_mq`): throughput may be unexpectedly low on some 
configurations after the scheduler fixes in this release.
