we have released a firmware update for our internet appliance with
libreswan 3.9 patched with your first version in early august.
There is no problem since then.
I have done a short test with the patch from your new branch and it
seems ok, but unfortunately we have no scenario which uses the old
database format to test the upgrade process.
Maybe I find some time next week to setup some test scenarios.
