Summary

AI summary

Billing switched to Stripe‑direct while KillBill was removed from the platform.

Full changelog

A major platform and billing release.

Runtime upgraded to Java 17 on Tomcat 9, with config-ice updated and forked for JDK 21+ readiness, a modernized build toolchain, and CI/release moved to JDK 17. by @matusfaro in https://github.com/clearflask/clearflask/pull/197
Self-host fix: the newer JDK resolves the cgroup-v2 NullPointerException startup crash seen on Linux kernel 6.12+ (#163).

Billing now routes entirely through Stripe (or a no-op path for $0/grandfathered/comp accounts) — KillBill has been fully removed from the runtime and the stack.
Self-host & local no longer run KillBill/Kaui, simplifying the deployment considerably.
Orphaned/legacy accounts are migrated off KillBill to the no-op billing path.
Custom flat-yearly (per-customer yearly price) now works for non-Stripe accounts; variable Stripe plans display the actual per-account price.
Fixed the flat-yearly "add payment method" 500 and the landing/billing hero layout.

ACME DNS-01 challenges are now published reliably via Porkbun and verified against the domain's authoritative nameservers with a longer propagation wait, fixing intermittent wildcard-cert renewal failures.
