Starting with the release of Fusion 5.5.1, this policy is updated to the Lucidworks Version Support Lifecycle. For the Fusion 5.5.0 and earlier policy, see Lucidworks Fusion Product Lifecycle.

​
Lucidworks Version Support Lifecycle

The Lucidworks Version Support Lifecycle describes the phases during which Lucidworks software is eligible for hotfixes and support. Lucidworks understands the importance of upgrade planning for our customers and partners. With the release of Fusion 5.5.1, Lucidworks simplified the release process to Rapid Release Support and Long-Term Release Support.

​
Policies

​
Long-Term Support Release Policy

Lucidworks understands that our customers need stability and predictability. Therefore, Lucidworks provides long-term support (LTS) releases for a two-year period, beginning at the time that the release is made Generally Available (GA). During this time, Lucidworks provides rapid and maintenance releases for bug fixes, security patches, and other updates to ensure the software remains stable and secure. Our long-term support releases are identified as such, and customers can choose to use these releases if they prefer a more stable and predictable experience. At the end of the support period, Lucidworks will notify customers and encourage them to upgrade to a newer version of the software to ensure continued security and stability. In addition to bug fixes and security patches, Lucidworks also provides customers with regular communications on the roadmap for the software, including new features and improvements that are planned for future releases. This will help our customers plan for future upgrades and take advantage of the latest improvements to the software. Overall, our support policy is designed to provide our customers with the flexibility they need to use our software in the way that works best for them. Whether customers need the latest features and bug fixes as quickly as possible or prefer a more stable and predictable experience, Lucidworks is committed to providing the support they need to be successful.

​
Rapid Release Support Policy

For rapid releases, Lucidworks understands that our customers need the latest features and bug fixes as quickly as possible. Therefore, Lucidworks provides support for the latest version of the software for a period of six months. During this time, Lucidworks will provide bug fixes, security patches, and other updates for the latest version of the software. Lucidworks will also provide customers with regular updates on the latest features and bug fixes included in each new software release. This will help our customers stay up-to-date and take advantage of the latest improvements to the software.

​
Maintenance Release Support Policy

For maintenance releases, Lucidworks provides customers with critical bug fixes and security patches for LTS releases outside of the scheduled release cycle, but it should be noted that those updates will not change the end support date for that specific release.

Reference tables

Extended support for Fusion 5.9 LTSWe are pleased to announce an extension to the support period for Fusion 5.9. This decision reflects our ongoing commitment to delivering exceptional service and ensuring the operational stability of your systems. The new end of support date for Fusion 5.9 is June 2026 (previously June 2025). Please be aware that during this extended period, maintenance updates will continue to be offered for Fusion 5.9. These updates may include bug fixes, improvements, and Kubernetes upgrades to maintain support with supported providers.

Kubernetes support

The end of support for a Fusion release may extend beyond the end of support for a related Kubernetes version. In these cases, maintenance releases are performed to add a newer Kubernetes version that ensures Fusion support continues for the full term. A Fusion upgrade is required for maintenance releases.
