The application and Edge components stay on 2026 R2.1. **Fixes** - The kernel installation step (./install.sh --plan kernel) no longer stops on Ubuntu 24.04 servers whose Python 3.12 packages differ from the bundled ones. Offline servers were the most likely to see this. - The face recognition similarity threshold is set to 0.7 for on-premises deployments, so people on watchlists are recognized again. **Known limitations:** A lower threshold can also increase false matches. ### 2026 R2.1 Core Update *Available 10-November 2026* Adds face recognition match thresholds. You can now set the match threshold per camera or rule, which lets you reduce false matches. Existing installations keep their current threshold until you change it. **Known limitations:** Requires 2026 R2.1 Core; threshold changes apply to new events only, not past ones. To install the update, read the instructions in the document below and follow the steps. ::File{src="https://api.archbee.com/api/presign/JzHznijrWxPLJLDUaV5A1/xAnUKOUV7FyNeon0MrPc-_iris-ai-guarding-core-2026-r2-1-runbook-adjusting-the-facial-recognition-similarity-threshold.pdf" label="IRIS+ AI Guarding Core 2026 R2_1 Runbook - Adjusting the Facial Recognition Similarity Threshold .pdf" isUploading="false"} ### 2026 R2.1. Core Hot-Fix *Available 13-October 2026* Fixes *./install.sh --plan* kernel failing with a *libpython3.12 *dependency error on Ubuntu hosts. Removes the optional *perf *diagnostic tools from the kernel package list, with no impact on the kernel, drivers or IRIS+ functionality. Verified on Ubuntu 24.04 only. A permanent fix will follow in the next installer build.
