Update to v26.08

The update to version v26.08 is performed according to the standard procedure, however, before starting MITIGATOR, additional steps are required.

In /srv/mitigator/.env, set the variable MITIGATOR_MASTER_SECRET. It contains master secret used to encrypt sensitive settings. Set it to an arbitrary string consistent across all cluster instances. It is recommended to generate the password using the following command:

openssl rand -hex 32
Info

The value of MITIGATOR_MASTER_SECRET must be preserved during MITIGATOR updates and after restores from backup. In case of its loss, sensitive settings have to be reconfigured. An example of such settings is two-factor authentication (2FA).
