*) ipsec - fixed dynamic L2TP peer and identity configuration missing after reboot (introduced in v6.44);

would be great to get this fix also to stable 6.44. Very annoying.

*) defconf - fixed IPv6 link-local address range in firewall rules;

a bit more details on this change? Those default rules are not upgraded automatically, so it would be good to see what exactly changed.
And in overall, it would be good to keep on wiki defconfs for each big releases.
