OpenDNSSEC 是一个实现了 DNSSEC 的开源解决方案，用来在发布到认证的域名服务器之前保护 zone 数据。
1. A new signer engine, written in C, was added.
2. Zones are maintained in memory, instead of in files on disk.
3. The python and python-4suite-xml dependencies were removed.
4. libhsm will... skip processing (and not create) any public keys if the per repository option <SkipPublicKey/> is set.
5. Keysharing was improved, so keys can now exist in different states on each zone for which the key is in use
