The OBS Project released OBS Studio 33.0 late on 23 October 2026 (UTC), after three release candidates. It is now marked as the latest release on the project’s GitHub page; the download pages on obsproject.com were still offering 32.2.2 when we checked on the morning of 24 October. For anyone who streams or records events with OBS, the two changes to plan around are the ones flagged during testing: third-party plugins move to a new location, and browser sources run on a much newer engine. This report is based on the published release notes and knowledge base; we have not tested the release.
Plugins in legacy locations work until 34.0
First-party plugins now sit in a new core folder, and third-party plugins have a new installation location and folder structure. Plugins installed in the old locations still load in 33.0 but will stop loading from OBS Studio 34.0, according to the release notes and the OBS knowledge base. Third-party plugins are not loaded at all in Safe Mode.
The developer notes also list changes that can affect plugins: an update to libnsgif is described as a breaking change for plugins that use OBS’s image file graphics functions, and support for FFmpeg 6 and 7 and for Qt 6.4 to 6.9 has been removed. A plugin that works in 32.2.2 is worth re-testing in 33.0 rather than assuming it carries over.
Browser sources move to CEF 150
The Chromium Embedded Framework used by browser sources and docks moves from version 127 to 150, a jump the release notes describe as moving from a July 2024 base to September 2026. The OBS Project says the work should be invisible to users and asks people to report any new problems with browser sources. Lower thirds, countdown clocks, sponsor loops and live poll results are often browser sources, so they are the first things to rehearse.
Other changes for event productions
- Studio Mode groups. Moving sources inside a group no longer makes them glitch, or show up live, in the Program view.
- Audio monitoring hotkeys. Monitoring for an audio source can now be controlled with hotkeys.
- Missing encoder check. OBS checks for missing encoders when it loads a profile, which helps when a profile is moved to another machine.
- Safe Mode and remote control. Safe Mode no longer starts the WebSocket server, so remote-control tools will not connect while OBS is running in Safe Mode.
- Preview and settings. Source snapping in the preview has been reworked with a visual indicator, and number fields now update only after pressing Enter.
- Recording and streaming fixes. File splitting for Hybrid MP4/MOV is improved, and an AMF B-frame calculation that could cause streams to disconnect is fixed.
- Platforms. Support for Ubuntu 24.04 is removed, with the Linux package built for Ubuntu 26.04; NVENC is enabled on Arm64; and a crash on starting OBS Studio on macOS 27.2 is fixed.
What to do before an event
Keep a show machine on the version you have rehearsed until the event is over. Install 33.0 on a spare machine first, check the plugin manager for plugins flagged as Legacy, load your real scene collection and profile, and run the whole running order, including every browser source and any remote control. Keep the 32.2.2 installer in case you need to go back. These are suggested precautions, not results of our testing.
