- The 4.52.0-20261101 image release updated the base image to Ubuntu 26.04 and built FFmpeg natively per architecture. Release

Why it matters
This week brings a new Helm chart release and image release with an Ubuntu 26.04 base, plus a nightly that correctly lists its versions. Fixes for KEDA scaling and video port binding affect users of the chart and browser nodes, and outdated Edge test versions were removed.

Week of October 19, 2026
What shipped
- Published Helm chart selenium-grid-0.62.1, using image tag 4.51.0-20261010 and tested against several Kubernetes and Docker runtime versions. Release
- Moved the base image in Base/Dockerfile and.ffmpeg/Dockerfile from Ubuntu 24.04 to Ubuntu 26.04 LTS, dropping the deadsnakes PPA because python3.14 ships natively. Pull request #3272
- Changed build-ffmpeg.yml to build FFmpeg natively per architecture and then merge, instead of building amd64 and arm64 in one buildx call with QEMU emulation. Pull request #3273
- Updated stale default image tags to 4.51.0-20261010 across values.yaml, docker-compose files, kubernetes manifests and docs. Pull request #3275
- Hardened
update_tag_in_docs_and_files.shso a missed tag match no longer leaves files silently stale. Pull request #3276 - Shipped a nightly build including the base image bump to Ubuntu 26.04, native per-architecture FFmpeg builds and a chart 0.62.0 changelog update. Release
Why it matters
This week fixes a tag update script that had matched nothing in 51 files since the 4.49.0 release, so default image tags in the Helm chart, compose files, manifests and docs are current again. The base image also moves to Ubuntu 26.04 LTS, and FFmpeg builds are split per architecture instead of relying on emulation. Chart 0.62.1 carries image tag 4.51.0-20261010.
Changelog entry
- Release Helm chart selenium-grid-0.62.1 using image tag 4.51.0-20261010. Release

- Build FFmpeg natively per architecture and merge instead of one emulated multi-platform build. Pull request #3273
- Catch up stale default image tags to 4.51.0-20261010 across chart values, compose files, manifests and docs. Pull request #3275
- Harden
update_tag_in_docs_and_files.shagainst silent staleness when a tag match is missed. Pull request #3276 - Nightly build with the Ubuntu 26.04 base image and per-architecture FFmpeg builds. Release
This week: Helm chart 0.62.1 with image tag 4.51.0-20261010. Stale default image tags caught up across 51 files and the tag update script hardened so it can not silently miss again. Base image moved to Ubuntu 26.04 LTS, and FFmpeg now builds natively per architecture.
This week in docker-selenium: Helm chart selenium-grid-0.62.1 is out, using image tag 4.51.0-20261010. A tag update script had been matching nothing in 51 files since the 4.49.0 release; stale default image tags in values.yaml, the docker-compose files, kubernetes manifests and docs are now caught up to 4.51.0-20261010, and the script is hardened so a missed match no longer leaves files silently stale. The base image in Base/Dockerfile and.ffmpeg/Dockerfile moved from Ubuntu 24.04 to Ubuntu 26.04 LTS, dropping the deadsnakes PPA since python3.14 ships natively. FFmpeg builds now run natively per architecture and merge, instead of emulating arm64 with QEMU. A nightly build includes these changes.
Week of October 12, 2026
What shipped
- Released image tag 4.51.0-20261010 built against Selenium Grid 4.51.0, with node and standalone browser versions updated for backward compatibility. Release
- Published Helm chart selenium-grid-0.62.0 using image tag 4.51.0-20261010, tested on Kubernetes versions v1.31.14, v1.32.13, v1.33.13 and v1.35.8 and Docker versions 27.5.1, 28.5.2 and 29.1.1. Release
- Released image tag 4.50.0-20261010 built against Selenium Grid 4.50.0. Release
- Published Helm chart selenium-grid-0.61.0 using image tag 4.50.0-20261010, tested on Kubernetes versions v1.31.14, v1.32.13, v1.33.13 and v1.35.8 and Docker versions 27.5.1, 28.5.2 and 29.1.1. Release
- Published Helm chart selenium-grid-0.60.0 using image tag 4.49.0-20260909, tested on Kubernetes versions v1.31.14, v1.32.13, v1.33.13 and v1.35.8 and Docker versions 27.5.1, 28.5.2 and 29.1.1. Release
- Fixed the deploy workflow so a dispatched version now reaches the build-test job, which previously built and tested 4.51.0 while promoting and releasing those images under the 4.50.0 tag. Pull request #3264
- Fixed latest tag selection, which sorted tags lexically by build date suffix and could pick a stale tag, causing the chart bump to be skipped. Pull request #3254
- Dropped backward-compatibility Edge versions whose driver Microsoft has pruned, after builds failed on missing drivers. Pull request #3263
- Added an early check for a stale but non-blank build date, so the build fails before three retries instead of after. Pull request #3256
- Made the edge, chrome, firefox and chrome-for-testing release workflows fail fast when reuse-base is true but grid-version is blank. Pull request #3255
Why it matters
This week moves the images and Helm chart forward to Selenium Grid 4.51.0 and aligns chart releases with the matching image tags. Several CI fixes address release workflows that could publish images under the wrong version tag or skip a chart bump, which matters to anyone relying on tag names to know what they are pulling. Backward-compatibility Edge versions whose drivers are no longer available were removed from testing.
Changelog entry
- Image tag 4.51.0-20261010 released with Selenium Grid 4.51.0 and updated node and standalone browser versions. Release
- Helm chart selenium-grid-0.62.0 released using image tag 4.51.0-20261010. Release
- Image tag 4.50.0-20261010 released with Selenium Grid 4.50.0. Release
- Helm chart selenium-grid-0.61.0 released using image tag 4.50.0-20261010. Release
- Helm chart selenium-grid-0.60.0 released using image tag 4.49.0-20260909. Release
- Updated Selenium Grid to 4.51.0 with backward browser versions. Pull request #3267
- Updated Selenium Grid to 4.50.0 with backward browser versions. Pull request #3257
- Deploy version input now reaches build-test and build-images, so dispatched runs no longer build one version and release it under another tag. Pull request #3264
- Fixed latest tag selection that ranked tags lexically and could skip the chart bump. Pull request #3254
- Added an early check for a stale but non-blank build date before the build starts. Pull request #3256
- Made browser release workflows fail fast when reuse-base is true but grid-version is blank. Pull request #3255
- Dropped backward-compatibility Edge versions whose driver Microsoft has pruned. Pull request #3263
Released image tag 4.51.0-20261010 with Selenium Grid 4.51.0 and Helm chart 0.62.0. Also out: 4.50.0-20261010 with chart 0.61.0, and chart 0.60.0. CI fixes now pass the dispatched version through to build-test, pick the latest tag correctly, and fail fast on blank or stale inputs
Image tag 4.51.0-20261010 is out with Selenium Grid 4.51.0, along with Helm chart selenium-grid-0.62.0. Also released this week: image tag 4.50.0-20261010 with chart 0.61.0, and chart 0.60.0. Each chart is tested on Kubernetes versions v1.31.14, v1.32.13, v1.33.13 and v1.35.8 and Docker versions 27.5.1, 28.5.2 and 29.1.1. On the CI side, a dispatched version now reaches the build-test job, so images are no longer built at one version and released under another tag; latest tag selection sorts correctly so the chart bump is not skipped; builds fail fast on a blank grid-version or a stale build date instead of after retries. Backward-compatibility Edge versions whose driver Microsoft has pruned were dropped from testing.
