Thanks to all the OpenWrt developers.

Six hours up
All appears to be fine on a Archer C2600 v1.1 with BanIP, Adblock and irqbalance.

There's a regression on TP-Link TL-WDR4900 v1 (mpc85xx/p1010). Wifi is down after upgrade. It looks like from the 21.02.3 -> 21.02.4 upgrade, but still in 21.02.5 - see for details. Workaround is to manually fixup /etc/config/wireless and then remove or edit /etc/hotplug.d/ieee80211/05-wifi-migrate

I keep getting this alot after switching to 21.02.5.


when installing packages.

pkg_hash_check_unresolved: cannot find dependency kernel (= 5.4.215-1-eef61aad9d9205d0f312846abba7ba7f)

Running fine and stable for 2 days on WT1900ACSv2

Modem-manager is not working well on 21.02, I backported a series of fixes: for it which I hope will be included in the next service release.

thank you for the development!

I had to reinstall relayd, other than that running good.

Is there a plan for a 21.02.6?

Probably a last maintenance release just before the end-of-life in April 2023.
