This month we fixed last month's link-time regression related to DWARF passes by adding an optional "dwarf" crate feature. This is still not optimal: projects that are linking to both the wasm-opt crate and the LLVM source code cannot get DWARF passes in binaryen because of duplicate symbols. At this time I do not have a better fix planned.

This project continues to have problems with long build times, and an issue has been filed suggesting another fix: to download pre-built binaryen archives for common platforms. I have not looked at the issue yet, but it is a potentially viable solution, probably not doable within the remaining time of this contract.

November will be the final month of this contract. I would like to discuss with somebody whether we should do this maintenance contract again next year (there are pros and cons); or even whether there are other infrastructural projects the w3f needs help with.

The long-awaited bug fix for unicode on windows - the one big bug I promised to fix in this contract - is fixed upstream but has not made it into a binaryen release yet. Presumably it will be in the next release and I will commit to getting that release into the wasm-opt crate even if the contract expires and is not renewed.

Hi @brson. Thanks for the delivery. I am happy to report that it is already accepted. You can find the evaluation notes here.

As for a new agreement, I am going to check internally.
