Lago is committed to providing reliable, transparent, and durable software for teams building and operating critical billing infrastructure. Our self-hosted offering is designed to support long-term production use while continuing to evolve alongside customer needs and modern technology stacks.
This End of Service Life (EOSL) Policy clearly defines the support lifecycle for Lago self-hosted releases. It outlines how long each release is supported, what level of support customers can expect at each stage, and when upgrades are required.
By following this policy, Lago demonstrates its commitment to being a dependable long-term partner. Customers can confidently plan upgrades, manage risk, and make informed infrastructure decisions, while minimizing operational disruption and avoiding unexpected end-of-support scenarios.
Major Release
A release that introduces breaking changes or requires explicit customer action to maintain compatibility or functionality, such as schema changes, configuration updates, or data migrations.
Minor Release
A backward-compatible release that introduces new features or improvements.
Maintenance Release
A backward-compatible release that includes bug fixes and security updates.
Long-Term Support (LTS) Release
A release designated by Lago for long-term production use and extended support. (Not all releases are designated as LTS releases.)
EOSL (End of Service Life)
The point at which a release is no longer supported.
Premium Support
The initial support phase during which Lago provides full maintenance, updates, and technical support.
Limited Support
The secondary support phase during which Lago provides reduced maintenance focused on security and critical issues only.

| Maintenance Release | A backward-compatible release that includes bug fixes and security updates. |
| Long-Term Support (LTS) Release | A release designated by Lago for long-term production use and extended support. (Not all releases are designated as LTS releases.) |
| EOSL (End of Service Life) | The point at which a release is no longer supported. |

| Limited Support | The secondary support phase during which Lago provides reduced maintenance focused on security and critical issues only. |
This policy applies to Lago self-hosted LTS releases only.
Non-LTS releases, including non-LTS Major Releases, do not follow the long-term support lifecycle defined in this policy.
Each Long-Term Support Release follows a four-year support lifecycle:
After this period, the release reaches End of Service Life (EOSL).
Minor and patch releases inherit the lifecycle of their associated LTS release.
During the Premium Support phase, Lago provides full support and maintenance for the release.
Includes:
Customer Expectations:
Customers are encouraged to stay current with the latest patch releases.
During the Limited Support phase, Lago reduces active maintenance while continuing to provide stability and security coverage.
Includes:
Does Not Include:
Customer Expectations:
Customers are expected to plan and execute an upgrade to a newer supported LTS release during this phase.
Once a release reaches EOSL, Lago no longer provides maintenance or support.
After EOSL:
Customers running EOSL versions do so at their own risk.
Lago announces major releases publicly at the time of availability.
The EOSL date is calculated as two (2) years from the LTS release date.
Lago will make reasonable efforts to remind customers as a release approaches Limited Support and EOSL milestones.
Upgrades are supported only between supported releases.
Lago strongly recommends upgrading to the latest major release within 6 months of release.
Direct upgrades from EOSL versions may not be supported and could require intermediate upgrade steps.
If a third-party dependency reaches its own end of life during the support window of a Lago LTS release, Lago may require customers to upgrade that dependency to continue receiving support, security fixes, or maintenance.
LTS designation is a company decision made after general availability, following a stabilization period.
Not all releases will be designated as LTS.
LTS designation does not imply a major product version or marketing milestone.
This policy is effective as of 1/1/2026.
The policy applies going forward. Existing releases will be assigned LTS or non-LTS status and corresponding support timelines will be communicated separately.
Lago may revise this policy as necessary to reflect product evolution, security requirements, or operational changes. Changes will not retroactively shorten the support period of already released versions.
