Changes in version 141.0.7390.43.1:
- Enable support for the DrumBrake WebAssembly interpreter previously exclusive to Microsoft Edge to support WebAssembly when JIT compilation is disabled. JIT compilation is disabled by default in Vanadium with a per-site toggle to opt into it for improved performance that's rarely needed. Vanadium also blocks dynamic code generation via seccomp-bpf in processes other than the per-site renderer sandboxes for sites where the user has enabled JIT compilation. WebAssembly normally depends on JIT compilation and users previously had to enable the per-site JIT toggle for sites requiring it even if the improved performance of JIT compilation wasn't needed. It should no longer be necessary to enable the per-site JIT toggle for compatibility reasons, only if users want to improve the performance of a demanding web application. Certain optional WebAssembly features aren't yet supported by the DrumBrake interpreter but this shouldn't reduce compatibility in practice since dynamic detection with fallback code is already required for broad compatibility.
A full list of changes from the previous release (version 141.0.7390.43.1) is available through the Git commit log between the releases.
This update is available to GrapheneOS users via our app repository and will also be bundled into the next OS release. Vanadium isn't yet officially available for users outside GrapheneOS, although we plan to do that eventually. It won't be able to provide the WebView outside GrapheneOS and will have missing hardening and other features.
