In the rapidly evolving database ecosystem, understanding the End-of-Support (EOS) and End-of-Life (EOL) schedules for each Tarantool version is crucial for maintaining stable operations. This comprehensive guide covers the support timeline for all Tarantool versions.
1. What is Tarantool? – High-Performance In-Memory Computing Platform
Tarantool is an open-source in-memory database and application server developed in Russia, distributed under the BSD 2-Clause license. This solution goes beyond a simple database to serve as a complete computing platform.
Key features include a high-performance scripting engine based on LuaJIT, cooperative multitasking, asynchronous I/O, persistent queues, sharding, and MySQL/PostgreSQL integration capabilities. Its ability to process data at ultra-high speeds in memory makes it widely used in web services handling large-scale traffic and real-time analytics systems.
2. New Release Policy – Clearer Version Management System
Since 2023, Tarantool has reformed its previously complex release policy to a SemVer-like format. The new policy uses MAJOR.MINOR.PATCH format and has been applied since version 2.10.0.
Key changes in the new policy:
- Third version number: Previously distinguished between pre-release/stable versions, now used for patch (bugfix-only) releases
- Pre-release notation: Changed to suffix format like
3.0.0-alpha1,3.0.0-beta2 - LTS series: Unlike before when only 1.10 was LTS, now 2.11 is also an LTS version with 4-year support
3. Currently Supported Tarantool Versions (September 2025)

Importance of LTS Version 2.11
Tarantool 2.11 is currently the only Long-Term Support (LTS) version, guaranteed maintenance for 4 years. Released in May 2023 and supported until May 2027, it’s recommended for enterprise customers seeking stable operating environments.
Considerations when choosing 2.11 LTS:
- ✅ 4-year long-term support: Stable maintenance until May 2027
- ✅ Production-proven: Sufficient operational experience accumulated
- ✅ Backward compatibility: Full compatibility from 1.10.x
- ✅ Enterprise foundation: Base version for TDG 2.12.x
- ⚠️ Limitation: Cannot use latest 3.x features
4. End-of-Life Versions
These Tarantool versions no longer receive security patches or bug fixes. If you’re using any of these versions, immediate upgrade to supported versions is required:
