# UP.Capture v1.12.0

**Published: 2026-08-25**

### BUG FIXES

* Resolved an issue where editing certain channels caused the application view to crash.
* Fixed an issue preventing recordings from including closed captions and causing audio/video synchronization drift.
* Resolved a performance bug that caused long recordings to fail after 24 hours of system uptime.
* Fixed slow recording speeds for AVC-Intra outputs to ensure real-time capture performance.
* Resolved memory and stream handling issues that caused system instability during active preview sessions.
* Fixed an interface bug where table headers within expanded rows stayed stuck on screen while scrolling.

### NEW FEATURES

* Added support for **redundant live sources** to ensure uninterrupted signal capture during stream failovers.
* Captures now include built-in file name validation to prevent errors and automatically hold channels in draft mode until valid file naming rules are met.
