The website says (http://hibernate.org/orm/releases/5.1/) version 5.1.17 is available.
I can't download through maven with this dependency:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.1.17.Final</version>
</dependency>

It's says that "Failure to find org.hibernate:hibernate-core:jar:5.1.17.Final in https://repo.maven.apache.org/maven2"

It's not mentioned at https://repo.maven.apache.org/maven2/org/hibernate/hibernate-core/ or at https://search.maven.org/artifact/org.hibernate/hibernate-core/5.1.17.Final/jar
