Release Note: 3.7.0 (2026-01-06)​

Focus: Improved Compatibility with Older Machines​

Notable Changes Since v3.6.1​

Enhanced CPU Compatibility​

• Broader Hardware Support:
  Updated build configurations for Windows, Linux, and macOS to increase compatibility with older CPUs by removing architecture-specific compiler flags.
  
  • On Linux/macOS:
    Dropped the -march=x86-64-v3 flag from custom vcpkg triplets (x64-linux-obs.cmake, x64-linux-obs-asan.cmake, x64-osx-obs.cmake, x64-osx-obs-asan.cmake).
    Result: Builds will now run on CPUs older than x86-64-v3 baseline (e.g., pre-Haswell Intel & pre-Zen AMD processors).
  • On Windows:
    Removed /arch:AVX2 from Windows triplets (x64-windows-static-md-obs.cmake, x64-windows-static-md-obs-asan.cmake).
    Result: Compatibility is restored for CPUs lacking AVX2 instruction set support.
• Sanitizer Support Remains:
  Address Sanitizer (-fsanitize=address or /fsanitize=address) flags are still present in sanitizer-enabled builds, but no longer enforce a minimum CPU architecture.

Benefits​

• Portability:
  Users on legacy or older hardware can now build and run the application without encountering "illegal instruction" or similar errors due to unsupported CPU flags.
• Simplified Build Configuration:
  Easier for users to customize and cross-compile, as triplets now use more generic compiler options.

---

Upgrade Note:
No action required for existing users, but anyone previously unable to build or run on older machines is encouraged to try this release.

Live Background Removal Lite 3.6.0 Release Notes​

Happy New Year, everyone! We’re excited to announce version 3.6.0 of LiveBackgroundRemovalLite—your high-performance, crash-resistant OBS plugin for real-time background removal. This release brings important upgrades focused on lifecycle handling, error logging, licensing clarity, coroutine utilities, improved file name handling, and general polish across the codebase. Here’s what’s new since 3.5.5:

---

Major Features & Improvements​

OBS Filter Lifecycle Event Support​

• The plugin now responds to OBS filter lifecycle events, including activate, deactivate, show, and hide.
• These events are handled robustly, allowing for better resource management and instant frame refreshing whenever you toggle visibility or activation.
• New lifecycle events were introduced to make the plugin more stable, especially when a filter or source is switched to be active or shown. You should experience fewer glitches and more consistent plugin performance as you switch scenes or toggle sources.
• The rendering context forcibly processes frames on these events, improving filter responsiveness and reliability.

Improved File Name Handling​

• You can now use file and folder paths containing non-ASCII characters (such as Japanese, Chinese, emoji, or other "fancy" characters) without issues. This update ensures your backgrounds and sources load correctly, no matter how creative your path names are.

Improved Logging with Structured Error Codes​

• All logger error and warning messages have been standardized. Instead of verbose strings, you’ll now find concise error codes like "MainPluginContextIsNullError" or "MemoryBlockAcquisitionError" in the logs.
• This helps with diagnostics, parsing log files, and tracking down issues faster.

License and Attribution Updates​

• Source files now use SPDX license identifiers, improving clarity and compatibility with automated license checking tools.
• LiveBackgroundRemovalLite modules consistently reference GPL-3.0-or-later, and attribution wording has been updated.
• The SelfieSegmenter module has been relicensed from GPL to the more permissive MIT License.
• Module naming in license headers has been corrected and harmonized.

Coroutine & Async Utilities Expanded​

• The KaitoTokyo::Async library now includes a new MPSC Channel for high-performance, coroutine-friendly multi-threaded work, along with safe shutdown and exception handling.
• Added JoinTask and a join() function for synchronously waiting on coroutine completion.
• The core Task coroutine has been improved for robustness and documented for easier use.

Miscellaneous​

• Localization keys for the update checker were standardized—users across English, Japanese, and Korean locales benefit from clearer update messages.
• Project references, such as BridgeUtils → ObsBridgeUtils, are updated in build files and documentation for better consistency.

---

️ Developer Notes​

• Exception handling and robust logging wire into all new lifecycle event callbacks.
• Multiple internal refactors make the codebase easier to read, safer, and more maintainable.

---

Upgrade Guidance​

This version is a drop-in upgrade. The new lifecycle responsiveness means filters should behave better as you interact with OBS UI, especially when switching source visibility or reactivating filters rapidly. The improved file name handling will especially benefit users with non-English setups or personalized folder names.

We strongly recommend updating to 3.6.0 for improved reliability, Unicode path support, licensing transparency, and developer ergonomics!

Release Notes: 3.5.5​

What's New:

This release addresses an important compatibility issue for users with video sources that are not in the standard 16:9 aspect ratio.

Fixed​

• Improved Compatibility with Non-16:9 Video Inputs
  Previously, mask rendering and region of interest (ROI) alignment could appear incorrect or shifted when using video sources with an aspect ratio other than 16:9. With this update, the scaling and positioning for the ROI calculation have been overhauled to ensure proper centering and scaling regardless of your input video's aspect ratio or dimensions.
  The calculations now reference the segmenter’s own target dimensions and center the ROI more accurately, providing a more consistent and visually pleasing background removal effect across all video sources.

Upgrading​

Update as usual—no breaking changes or manual migration steps required.

Thanks for your feedback, and please let us know if you encounter any more edge cases or have suggestions!

Release diff: 3.5.4 → 3.5.5 (commit 5ab820d)
Contributed by @umireon

What's New in 3.5.4​

This release mainly tidies up the build configuration to make things simpler and smoother for both users and developers:

• Testing is now Opt-In:
  Tests will not be built by default. If you want to include tests, you’ll need to explicitly enable them. This helps reduce build times and keeps things clean for users who don’t need to run tests.
• Simpler CMake Presets:
  The configuration for enabling tests or sanitizers has been streamlined:
  • Only the BUILD_TESTING option is set in presets by default.
  • Redundant sanitizer options (ENABLE_ASAN, ENABLE_UBSAN) have been removed from most platforms. These are now only present where needed (like the macOS dev ASAN/UBSAN build).

These changes make it easier to build the plugin for everyday use, and clearer when and how development/testing features are enabled.
