This is the final delivery on this project.

This month had almost no billable activity, though there were two issue filed about solving build time problems by reusing static binaryen libraries during the build.

Although the contract is over I will make at least one more release when binaryen 117 is released, as that will contain a Unicode fix that I worked on throughout the year.

I will probably circle back to the project to update binaryen once a year or so, but am not likely to make major improvements.

This project went smoothly, and I think was pretty inexpensive - we spent significantly less than the grant was approved for.

I am happy to work with the w3f again in the future on infrastructural projects related to compilers, runtimes, etc. Feel free to contact me.
