 ## Deployment
 
-- Built image is pushed to Gitea registry as `192.168.1.95:3000/timothy/ersatztv-ffmpeg:7.1.1`
+- Built image is pushed to Gitea registry as `192.168.1.95:3000/timothy/ersatztv-ffmpeg:8.1.2`
 - Referenced by ErsatzTV's `docker/Dockerfile` as the `runtime-base` stage
-- Only amd64 — jazz (192.168.1.99) is x86_64
+- Only amd64 — bumblebee (192.168.1.99) is x86_64
 
 ## Conventions
 
 - Keep all library versions pinned and explicit
-- Test FFmpeg binary works before pushing: `docker run --rm ersatztv-ffmpeg:7.1.1 -version`
+- Test FFmpeg binary works before pushing: `docker run --rm ersatztv-ffmpeg:8.1.2 -version`
 - When bumping FFmpeg or library versions, update RELEASE_VERSION in `.gitea/workflows/build.yml`
