Key Features & Fixes

Release Purpose

: Primary stability fix for the 5.4.x branch. It resolved a high-priority bug where upgrading to 5.4.9 could accidentally switch WPA Enterprise networks to an "Open" state, posing a security risk. Key Features & Fixes : unifi-installer.exe 5.4.11

Stabilization Phase (5.0 – 5.4) – Focus on solidifying the core platform, eliminating data‑corruption bugs, and providing enterprise‑grade deployment tools (silent install, service wrappers).
Feature Expansion Phase (5.5 – 6.x) – Introduce new capabilities such as Network‑wide AI‑driven RF optimization, Zero‑Touch provisioning for remote sites, and integrated security gateways.

Step 2 – Re‑adopting Devices

Use Windows Add/Remove Programs → “Ubiquiti UniFi”
Or run from command line:
```
msiexec /x UniFi-product-code /quiet
```
The installer leaves behind the MongoDB data directory by default. Manually delete %PROGRAMDATA%\Ubiquiti UniFi\data if no longer needed.
