UniFi 3.2.1 is the official General Availability Release. For change logs for beta releases, see 3.1.10-RC Release Notes

NOTE:

Make sure you always do a backup before any updates, especially if you plan to upgrade your existing installation.

Release Note

Starting from V3, UniFi controller will honor "Automatic Firmware Upgrade" settings. APs with incompatible versions will show up as "Connected (needs upgrade)" where no provision will be performed.

A new wireless uplink is introduced, you would need to upgrade the isolated/downlink AP first.

See footnote 2 and 3 for voucher / portal customization.

See footnote 4 for API changes.

See v2->v3 Migration FAQ for more information.

New Features Introduced in V3

Multi-site management, read-only admin support

Instead of running multiple controllers, now you can use one controller to manage multiple sites.

Each site has its own configurations, maps, statistics, guest portals and is logically separated.

Moreover, you can delegate administrative rights (readonly/readwrite) to other people.

Seamless Roaming - Zero-Handoff(ZH) - Still in beta state.

Running radios on the same channel with the same BSSID. No controller is required for its operation.

UAP AC ZH is still in development.

WLAN Groups

Now you can create multiple WLAN groups and assign them to an AP's radio.

Other Features

Rogue AP detection

More descriptive email alerts

Basic SNMP support

Enhanced load balancing per radio

Voucher customization

Additional payment gateway support (Stripe, QuickPay, Authorized.Net, MerchantWarrior)

Ability to reset current statistic

CTRL - Fixed Rogue AP reports encrypted when AP is open security.

How to perform the upgrade

We're being more cautious in pushing releases to the world. Following Google's model, we'll have three release channels

stable (widely used, most stable)

rapid (soaked in beta for a while)

beta (cutting edge)

For Debian-based system, simply do

sudo apt-get update sudo apt-get install unifi-rapid

How to play safe?

UniFi stores everything under <UNIFI_BASE>/data/ . Keeping a copy will get your base covered. You can even install the new version, stop it, copy the data/ over it, and restart the controller.

How to downgrade?

The DB schema is drastically different and downgrade is not possible. Make sure you have a backup of prior version. After downgrading the controller, you can downgrade the AP firmware.

Known Limitations

UAP-AC - Rogue AP detection will only search for rogue AP on first power up. It will not continuously update rogue AP list during runtime.

UAP-AC - SNMPv1 not yet supported. Currently in development.

Zero Handoff not supported on UAP-AC yet. Currently in development.

Wireless Uplink not supported on UAP-AC yet. Will be release as an alpha and by invitation only in the next few weeks.
