Mikrotik devices come in a variety of architectures and form-factors. Fortunately the firmware versioning and built levels are the same across all platforms. The main variant is the architecture, which might be a different chip for each device model.
The firmware testing quality is fairly high, so there is little reason to wait to update after a firmware version comes out.
Below is a table of the latest firmwares for Mikrotik devices that are in the mesh:
Current Version: 6.42.7
- Login to your Mikrotik box Web UI ( CLI if you know how )
- Go to WebFig > Files section, upload the firmware file
- Reboot the router
- The firmware version is visible at the top of the Web UI, watch for the new version
