OpenSSL 3.5 will be the next long term stable (LTS) release

We are pleased to announce that OpenSSL 3.5 will be the next long term stable (LTS) release. Per OpenSSL’s LTS policy, 3.5 will be supported until April 8, 2030.

The previous LTS (OpenSSL 3.0) will continue to be fully supported until September 7, 2025 and receive security fixes until September 7, 2026. Projects that currently depend on 3.0 are strongly encouraged to switch to OpenSSL 3.5 once it has been released.

In addition, the OpenSSL Corporation and Foundation have agreed to designate an LTS every two years. That means there will be an LTS release in April of 2027, another in 2029, and so on. As always, each LTS will be supported for 5 years with the final year’s support being security patches only. For more information, please see the OpenSSL Library Roadmap.

Predictable LTS releases should help projects that depend on them plan their own development schedules. There will always be at least two supported LTS releases of OpenSSL in addition to predictably timed regular releases. This conforms to the OpenSSL value of promoting trust and confidence.
