# [EPF-5] Week 21
## This Week
* Sync and polish [the PR for Grandine's Windows support](https://github.com/grandinetech/grandine/pull/42).
+ For syncing PR to develop branch easier, I do a squash on all commits. And finally CI passed again.
+ After contacting with upstream, the relevant Windows stats successfully rely on winsafe. This also greatly simplifies the implementation of the metric_sys mod.
+ Other changes are also made according to the review comments even with some of the changes which I not fully agree with.
* Extended investigation.
+ Cross-architecture support is an interesting extension for my proposal. I met the building prbolems for Grandine on RISC-V. I will see if I have more time in the near future to fix this.
* Prepare the presentation at Devcon.
+ Although my proposal is not too big, it is found that it can reveal some big problem in the existing ecosystem of Rust based consensus clients. I will share my thoughts about that in Devcon.
## Next Week
* Let's meet at the Devcon 7 SEA.
