Short answer: as of November 2, 2026, the current FortiOS release on each branch is 8.0.2, 7.6.8, 7.4.13, 7.2.14 and 7.0.19. The first four came out on October 22, 2026 and are the versions Fortinet named as fixed in its coordinated security update. If you run an older build on any of those branches, upgrading to the latest build of your branch is the first move.
Last checked: November 2, 2026. Every version number, build number and date below comes from Fortinet’s Document Library release notes or Fortinet’s own announcements. We recheck this page against those sources and change the date when we do.
Current FortiOS release for each branch
| Branch | Latest release | Build | Released | Source |
|---|---|---|---|---|
| 8.0 | 8.0.2 | 0251 | October 22, 2026 | 8.0.2 release notes |
| 7.6 | 7.6.8 | 3744 | October 22, 2026 | 7.6.8 release notes |
| 7.4 | 7.4.13 | 2933 (a few models use a special build, see below) | October 22, 2026 | 7.4.13 release notes |
| 7.2 | 7.2.14 | 1778 | October 22, 2026 | 7.2.14 release notes |
| 7.0 | 7.0.19 | 0696 | January 30, 2026 | 7.0.19 release notes |
Fortinet publishes release dates in the Change Log of each release notes document. The Document Library branch pages list these versions as the newest for each branch: FortiOS 8.0, FortiOS 7.6, FortiOS 7.4, FortiOS 7.2, FortiOS 7.0.
To confirm which build a device runs, log in to the CLI and run get system status. On 7.4.13, a few models (FGR-60G, FGR-60G-5G, FGR-60G-M12, FGR-70G-5G and some others) ship on a special branch with a different build number. Fortinet tells you to check the Branch point field in that output, and the 7.4.13 release notes list the models and their builds.
Why the October 22, 2026 releases matter
On October 21, 2026, Fortinet’s CISO announced a coordinated set of security updates for FortiOS, FortiManager and FortiAnalyzer, due the next day, and urged customers to prioritize internet-facing devices. The post lists these affected and fixed FortiOS versions:
| Branch | Affected versions | Fixed in |
|---|---|---|
| FortiOS 8.0 | 8.0.0 to 8.0.1 | 8.0.2 or above |
| FortiOS 7.6 | 7.6.0 to 7.6.7 | 7.6.8 or above |
| FortiOS 7.4 | 7.4.0 to 7.4.12 | 7.4.13 or above |
| FortiOS 7.2 | 7.2.0 to 7.2.13 | 7.2.14 or above |
Fortinet’s post does not list a fixed 7.0 release in that table. The 7.0 branch’s newest build is still 7.0.19 from January 2026, so a FortiGate on 7.0 has to move to a newer branch to get the October fixes. Fortinet also said the advisories describing these fixes would be published on its PSIRT page at the next Patch Tuesday, November 10, so the CVE details were not public when we last checked.
We covered the release when it landed: Fortinet ships critical FortiGate fixes today and won’t say what they fix until November 10. For flaws that are already being exploited, see our list of actively exploited Fortinet vulnerabilities in 2026.
FortiGate upgrade path: how to find yours
You cannot always jump straight from an old release to the newest one. Fortinet validates specific point-to-point upgrades and publishes them in its Upgrade Path Tool. The tool returns the shortest tested path between your current firmware and your target. Fortinet’s instructions are to take each hop in order, wait for services to settle between hops and not skip ahead.
- Run
get system statusand note your model, version and build. - Open the Fortinet Upgrade Path Tool, pick your model, your current version and the target version.
- Read the Special notices and Upgrade information sections of the release notes for every hop. They list removed features and one-off requirements.
- Back up the configuration before each hop. Fortinet notes that downgrading loses most configuration, so treat each hop as one-way.
- Upgrade in the order Fortinet gives for a Security Fabric: FortiAnalyzer, then FortiManager, then FortiGate devices, then managed FortiExtender, FortiSwitch and FortiAP units, then the rest.
Example paths from Fortinet’s tool
We ran the tool’s public lookup for a FortiGate-100F on November 2, 2026. A FortiGate-60F returned the same hops. Your model and exact build can change the result, so use these as an illustration and run the tool for your own device.
| Current version | Target | Path returned (build) |
|---|---|---|
| 7.6.7 | 7.6.8 | 7.6.7 (3704), 7.6.8 (3744) |
| 7.4.12 | 7.4.13 | 7.4.12 (2902), 7.4.13 (2933) |
| 7.4.13 | 7.6.8 | 7.4.13 (2933), 7.6.8 (3744) |
| 7.4.8 | 7.6.8 | 7.4.8 (2795), 7.6.6 (3652), 7.6.8 (3744) |
| 7.2.10 | 7.4.13 | 7.2.10 (1706), 7.2.13 (1762), 7.4.13 (2933) |
| 7.2.14 | 7.6.8 | 7.2.14 (1778), 7.4.13 (2933), 7.6.8 (3744) |
| 7.0.19 | 7.6.8 | 7.0.19 (0696), 7.2.14 (1778), 7.4.13 (2933), 7.6.8 (3744) |
| 6.4.15 | 7.6.8 | 6.4.15 (2095), 7.0.12 (0523), 7.0.14 (0601), 7.2.10 (1706), 7.4.8 (2795), 7.6.6 (3652), 7.6.8 (3744) |
| 7.6.7 | 8.0.2 | 7.6.7 (3704), 8.0.2 (0251) |
| 7.4.12 | 8.0.2 | 7.4.12 (2902), 7.6.8 (3744), 8.0.2 (0251) |
Two patterns show up. Staying inside a branch is usually one hop. Crossing branches usually means stepping through each branch in turn, and the tool picks the specific intermediate build for you.
Check these before you upgrade
- SSL VPN tunnel mode is gone from 7.6.3 onward. Fortinet’s release notes say tunnel mode was replaced by IPsec VPN that can use TCP port 443, that settings are not carried over, and that you must migrate before upgrading to 7.6.3 or later. See the 7.6.8 special notice.
- Older hardware may stop at 7.4. The 7.4.13 supported-model list includes FG-60E, FG-80E, FG-90E and FG-140E. The 7.6.8 list does not. Confirm your exact model in the release notes’ Introduction and supported models section before planning a jump to 7.6 or 8.0.
- 2 GB RAM models lose proxy features. The 7.6.8 release notes say FortiOS no longer supports most proxy-related features on FortiGate models with 2 GB of RAM or less, which covers the 40F, 60F and 50G series and their variants. Proxy-based inspection for SMTP, POP3, IMAP and NNTP came back in 7.6.5.
- Downgrades wipe most settings. Only operation mode, interface and management IPs, static routes, DNS, the admin account, session helpers and access profiles survive.
- Fabric members must match. The 7.6.8 notes say that when the Security Fabric is enabled, all FortiGate devices in it must run 7.6.8.
Support lifecycle for the branches
Fortinet extended the support dates for 7.4 and 7.6 by one year in March 2026, announced in customer support bulletin CSB-260330-1 and summarized in a Fortinet community technical tip.
| Branch | End of engineering support | End of support |
|---|---|---|
| 7.4 | May 11, 2027 | November 11, 2028 |
| 7.6 | July 25, 2028 | January 25, 2030 |
We did not find a Fortinet-hosted source for the 7.0, 7.2 and 8.0 dates that we could read today, so we are not listing them here. Check Fortinet’s product life cycle page in your support account for those branches.
How we keep this page current
- Version, build and date: the FortiGate / FortiOS branch pages and release notes in the Fortinet Document Library.
- Fixed-version guidance: Fortinet’s own announcements and, once published, its PSIRT advisories.
- Upgrade paths: Fortinet’s Upgrade Path Tool and the Upgrade information section of each release’s notes.
- We do not use third-party mirrors or forum posts for version numbers. If Fortinet publishes a newer build than the table shows, the Fortinet source wins.
FAQ
What is the latest FortiOS version?
As of November 2, 2026, the newest branch is FortiOS 8.0, whose latest release is 8.0.2. The latest 7.x releases are 7.6.8, 7.4.13, 7.2.14 and 7.0.19.
Which FortiOS version should I run?
Run the latest release on the branch your hardware and change process support. For 7.6, 7.4 and 7.2 that is 7.6.8, 7.4.13 or 7.2.14, which Fortinet lists as the fixed versions in its October 22, 2026 update. Use the release notes to check your model is supported before you change branches.
Can I upgrade straight from 7.2 to 7.6?
Not always. Fortinet only supports tested point-to-point upgrades. In the tool’s result for a FortiGate-100F, going from 7.2.14 to 7.6.8 passes through 7.4.13. Run the Upgrade Path Tool for your model and version.
Is there a fixed 7.0 release for the October 2026 update?
Fortinet’s October 21, 2026 post lists fixed versions for 8.0, 7.6, 7.4 and 7.2 only. The newest 7.0 release is 7.0.19, from January 2026, so move to a newer branch if your hardware allows it.
What does the build number mean?
The build number identifies the exact firmware image for a version, such as 7.6.8 build 3744. Run get system status to see yours. A few models run a special branch with a different build, and the release notes list them.
When will Fortinet publish details of the October 22 fixes?
Fortinet said the advisories would appear on its PSIRT page on November 10, 2026. Until then, the only public guidance is the list of fixed versions.
