Hibernate ORM 5.3.18 Release?

I see https://nvd.nist.gov/vuln/detail/CVE-2019-14900 lists that it is fixed in release 5.3.18 and 5.4.18; 5.4.18 was released over a month ago, but I don’t see any corresponding 5.3.18 release?

Is a 5.3.18 release planned to occur soon, or should 5.3 be considered “end of life”?

I didn’t seem to get a clear answer to this question on zulipchat: https://hibernate.zulipchat.com/#narrow/stream/132096-hibernate-user/topic/Hibernate.205.2E3.2E18/near/204119842
