Summary
The following information applies to the v18 release of Continuity Engine.
Continuity Engine 18
What's New
In-Product Notification
- Streamlined communication between customer's Engine Management Service and Neverfail's Notification Services.
- Easy-to-absorb messages fed directly to customers' EMS UI.
- Keep customers informed with product updates and company announcements.
Licensing Service Access only for Supported Versions - UX Improvements for Hardened Environments
EMS UI UX for Engine managed servers was improved in v18 in hardened scenarios, where EMS Web Console has no access to Licensing Services (i.e. internet):
- each managed server will show Product Version on grey background with tooltip message "Cannot validate support".
- offline licensing (only) is enabled for all the connected managed servers because version cannot be validated as supported.
Online Licensing Requirements (introduced with v17)
- Important: Engine Management Services (EMS) upgrade to v17 (or newer) is required for maintaining access to Licensing Services.
- Starting v17, license key issuance for a new or a renewed Software Subscription is viable only on currently supported versions of the software.
- EMS UI improved user-experience in displaying Engine version status: Supported, EoL soon or Unsupported.
Independent Identity Deployment Support
- Continuity Engine may be deployed in a Independent Identity (IID) cluster architecture via CLI Installer.
- ProServ driven deployments: additional requirements and post-deployment configuration may be needed, depending on the deployment scenario and protected application.
- Plugins will be changed to support IID application deployment (where applicable). In this release, System plugin was added to IID-supporting family.
EMS Alerting based on Managed Server Telemetry
- The first chapter in unlocking advanced monitoring and alerting is to enable our new telemetry service, which will seamlessly extract relevant information about events happening on the Engine nodes.
- v17 adds more to this feature by improving the telemetry data upload-via-EMS feature (unlocked in v16) for a deployment not managed via Engine Management Service.
- By enabling telemetry, you empower the EMS to deliver better monitoring and alerting for critical events that matter most to your business. This will translate into quicker response times, more accurate alerts, and ultimately, greater peace of mind knowing that your systems are running optimally.
- v18 enables In-Product Notification feature which may be used for announcing and alerting customers with relevant Engine information.
Better User Experience
Application Management - Automating Discovery and Protection via Dedicated Plugins (on-going)
- New plugins will be developed and added to Continuity Engine family, release by release. These plugins will replace the manual implementation of User Defined application protection.
- Application protection made simple. Homogeneous. Reliable.
Offline Licensing Management via EMS
- UX Improvements for hardened environments: managed server will show Product Version on grey background with tooltip message "Cannot validate support". Access to offline licensing is permitted.
- Self-service offline licensing based on telemetry data: customers may claim license keys directly from Engine Management Service for deployments which are not managed via EMS.
- Install Engine Management Service on any supported Windows machine with access to internet (i.e. Engine Licensing Server) then claim your license keys corresponding to your purchased software subscription from the Support section. Details in Self-Service Offline Licensing: How to Claim a License Key for a Deployment Not Managed via Engine Management Service.
New Version Availability and Download Published via EMS
- EMS UI alerts whenever a newer version is generally available, along with download link and release highlights.

More Secure
Latest Security Updates and Fixes for OpenJDK and Apache Tomcat
Continuity Engine's objective is to keep your systems up, running, protected, and safe. Having the latest security updates, fixes and patches for the used open-source software is critical. v18 is updated to:
New Supported Versions
VMware vCenter Server and VMware vCenter Converter Support

Licensing Updates
Licensing Service Access only for Supported Versions
- End-User License-Subscription Agrement changes are summarized in the below section extracted from Neverfail End-User Software Subscription License Agreement.
- License Key Issuance vs. Software lifecycle: License Key issuance for a new or a renewed Software Subscription is viable only on currently supported versions of the Software..
- Engine follows a software subscription term and rental licensing model. Engine Licensing Service (ELS) enables call-home features that power our software subscription based licensing. The new license service is free but is required for Term and Rental deployments. For more information on how the licensing works and upgrade notes please read Continuity Engine Licensing Model.
Backward Compatibility
Continuity Engine 18 Management Service is compatible with older supported versions of Engine (i.e. EMS 18.0 manages correctly, including licensing services, for all the supported CE versions 14/15/16/17).
- If I upgrade to Continuity Engine 18, will my perpetual license cease? Yes! You are accepting software subscription's requirements outlined in the new EULA for Term and Rental. Neverfail will generate new software subscriptions expiring the same day as the support was paid through. This means you will need to pay for support to continue software operations yearly or monthly depending on the type of subscription.
- Can I upgrade using the Upgrade Wizard from older/unsupported versions to Continuity Engine 18? Yes, the upgrade wizard is still supported. Keep in mind that Continuity Engine versions 6.7, 7.x, 8.x, 9.x, 10, 11, 12, 13 are currently End-of-Life (EOL). To ensure organization continued support and access to licensing services, you must upgrade to the latest Continuity Engine version.
When will Continuity Engine EOL? Check End of Life Policy for Neverfail Continuity Engine
Can I stay on previous versions of Continuity Engine? Yes, however, previous versions will eventually EOL and you will not be able to take full advantage of the new features of Continuity Engine v17. And evenly important, your systems will be more exposed to cyberattacks. For example:
