Pfsense-ce-2.8.0-release-amd64.iso.gz

If you are running pfSense 2.6.0 or 2.7.2, upgrading to 2.8.0 is more than cosmetic.

Warning: If you have a very old CPU (Intel Core 2 Duo or older, lacking POPCNT instruction), 2.8.0 will not boot. FreeBSD 14 requires LAHF/SAHF and POPCNT. Check your CPU before upgrading.

Do not upgrade blindly. Review these critical changes:

| Area | Change | Action Required | |------|--------|------------------| | CPU | Requires 64-bit with SSE2 | Pentium 4/Athlon 64 or newer. No 32-bit. | | Packages | Many legacy packages (e.g., squid 3.x, haproxy 1.8) removed | Switch to squid 4.x or haproxy 2.4+ from the package repo before upgrade. | | Captive Portal | RADIUS accounting formats updated | Update your RADIUS server dictionaries. | | RRD Graphs | Data format changed | Old historical data will be lost; backups of /var/db/rrd are not restorable. |

Recommendation: Take a full configuration backup (Diagnostics > Backup & Restore) and a ZFS snapshot (if using ZFS boot environments) before upgrading.

Why the .gz compression? The raw ISO is roughly 500 MB. The .gz compression shrinks it to approximately 300 MB, saving bandwidth and download time for the project's mirrors.

After years of steadfast service from the 2.7.x branch, the open-source firewall and routing community has been eagerly awaiting the next evolution of pfSense Community Edition (CE). With the release of pfSense CE 2.8.0, Netgate has delivered a significant update that bridges the gap between legacy stability and modern FreeBSD foundations.
