Upon upgrade of 2.1.5 to 2.2, strongswan did not start and quit with the following message:

Jan 24 16:12:39 ipsec_starter⁷³⁰⁰⁵: unable to start strongSwan -- fatal errors in config
Jan 24 16:12:39 ipsec_starter⁷³⁰⁰⁵: invalid config file '/var/etc/ipsec/ipsec.conf'
Jan 24 16:12:39 ipsec_starter⁷³⁰⁰⁵: /var/etc/ipsec/ipsec.conf:19: syntax error, unexpected EQ [=]
Jan 24 16:12:39 ipsec_starter⁷³⁰⁰⁵: Starting strongSwan 5.2.1 IPsec [starter]...

Line 19 of ipsec.conf is:
leftid = C=CH/ST=Aargau/L=Baden/O=TechFreak/emailAddress=XXX/CN=vpn.example.com

After changing the ASN.1 DN in the GUI and adding double quotes (") to the value:
"C=CH/ST=Aargau/L=Baden/O=TechFreak/emailAddress=XXX/CN=vpn.example.com"

this started to work again, and strongswan bootet up.

This should be checked in the GUI and automatically added to the value saved in the config file.
