Version compatibility¶
The correspondence between the Nebula Exchange release (the JAR version) and the Nebula Graph core release is as follows.
| Exchange client | Nebula Graph |
|---|---|
| 2.5-SNAPSHOT | nightly |
| 2.6.1 | 2.6.0, 2.6.1 |
| 2.5.1 | 2.5.0, 2.5.1 |
| 2.5.0 | 2.5.0, 2.5.1 |

| 2.0.1 | 2.0.0, 2.0.1 |
| 2.0.0 | 2.0.0, 2.0.1 |
JAR packages are available in two ways: compile them yourself or download them from the Maven repository.
If you are using Nebula Graph 1.x, use Nebula Exchange 1.x.
