Current Release Versions
There are always two versions of OpenNMS available: the stable or “production” release and the unstable or “development” release. Note that the term “unstable” refers to the amount of code that has changed and not the robustness of the software.
The current stable release is 1.10.3 (release notes).
The current unstable release is 1.11.0 (release notes).
If you wish to install a development snapshot of future 1.10 or 1.11 releases, see the “Choosing a Release” section of the tutorial for details.
