Only 2 hours of work this month.

Our patches to upstream Binaryen to enable unicode on windows are not going to be accepted as-is - the Binaryen authors have begun writing their own patches for this purpose.

We have received a request on the issue tracker to add support for in-memory operation. It's a feature that makes sense, but which is not supported by Binaryen's underlying file-oriented APIs, so implementing it requires more upstream work. I'm inclined to hack on it, and there's lots of budget since there's nothing else on the table for this project at the moment. If somebody disagrees, let me know.

No new Binaryen releases this month, but it's about time for a new one soon.

Internet Computer integrated the wasm-opt crate into one of their projects, and Holochain seems to have used it for some purpose. That's in addition to the 2 Polkadot projects and Stellar already using it. GitHub thinks 555 repos have wasm-opt-rs dependencies (mostly substrate forks). So this modest project has had a pretty nice impact.

Thanks for the delivery and the updates, @brson. It's great to hear the project being used in different places. And feel free to work on the in-memory support.

I have forwarded your invoice for processing.
