What is up everyone,

For over 11 a half years now, OPNsense is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, fast adoption of upstream software updates, modern IPv6 support, as well as clear and stable 2-Clause BSD licensing.

26.7, nicknamed "Xenial Xenops", features interface assignments and gateway groups via MVC/API, firewall rules now defaulting to MVC/API, outbound NAT to source NAT migration assistant, captive portal IPv6 support, Kea DDNS/custom options/dynamic prefix delegation, FreeBSD 15.1, OpenVPN 2.7, PHP 8.5, Python 3.13, plus much more.

The upgrade path for 26.1 will likely be unlocked later today. We want to ensure the upgrade goes as smoothly as possible so please be patient! :)

Migration notes, known issues and limitations:

The privileges "page-system-groupmanager" and "page-system-usermanager-addprivs" were merged into "page-system-groupmanager" and are no longer available separately. This was done to avoid the misconception that access to a user management page gives constrained rights to each page, but that is not the case. User management is a process involving all 3 pages.
The static PHP pages for firewall rule management have been moved to the "os-firewall-legacy" plugin which can be manually installed before or after the upgrade. All rules will continue to work regardless of the plugin being installed or not and are easily migrated using the given assistant.
Hyper-V guests may be producing panics on certain hosts with more than one virtual processor assigned. Make sure to snapshot beforehand and stay on 26.1.x until the situation is clear.
Since this is a major OS upgrade and OpenSSL changes from 3.0 to 3.5 third party repositories may interfere with your upgrade experience. Removing offending repositories and plugins may help; or wait for affirmation from the respective repository owners.
