We recently received some inquiries about how long we will support 1.x and 2.x with security fixes.

1.x will be supported for another 12 months up until August 2024 2.x will be supported for another 24 months up until August 2025

We also released https://github.com/NodeBB/NodeBB/releases/tag/v2.8.16 and https://github.com/NodeBB/NodeBB/releases/tag/v1.19.12 containing some of the fixes from the 3.x line. If you are not able to upgrade to 3.x we encourage you to upgrade to these releases.
