Dear friends and followers,
For more than 3 years now, OPNsense is driving innovation through modularising and hardening the code base, quick and reliable firmware upgrades, multi-language support, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.
We are happy to announce the immediate availability of the renewed OPNsense 18.1 images based on version 18.1.6. Apart from the numerous improvements since the initial release, the images contain three relevant fixes:
- Fix Unbound DNS parameter underflow on systems with higher number of CPUs
- Disable RRD health reporting by default on Nano images to reduce write cycles
- Disable TRIM by default on Nano images to prevent corruptions of the file system
The full list of changes of the OPNsense 18.1 series can be reviewed using their original announcements:
