Good, thanks for update, I was just checking we are aligned on this. ------------------------------ *From:* Anthony Roberts *Sent:* Thursday, June 25, 2026 3:11 AM *To:* Gleb Khmyznikov *Cc:* Omair Javaid ; CoreCollective Windows on Arm *Subject:* Re: [EXTERNAL] Re: [CoreCollective WoA] Public tracker updates Hi Gleb, I will attempt to drive sglang, I will try to speak to them next week - it's possible they may just not want to support Windows full stop (nginx was a case of this historically, they accepted PRs to build it, and allowed community builds, but wouldn't support it officially with builds). For temporalio, is cryptography shipping wheels now? As per Mayank's email, the work is already done, but it relies on cryptography to build. Therefore, I can't proceed until the upstream blocker is resolved. Thanks, Anthony On Wed, 24 Jun 2026 at 23:38, Gleb Khmyznikov wrote: follow up: NV works on cuda-python wheels and cuda-bindings.

Which is might be a good win for us if we can make the support happen. @Anthony Roberts do you see how we can reach them in DM? Can you drive this? - *tree-sitter-languages, pyiceberg* marked your findings in our tracker. - *cuda-bindings* I still didn't get the response from NV. They may be in a on fire situation, I see the signals about the potential delay of CUDA SDK public availability. - *temporalio* @Omair Javaid do you guys aligned on this with @Anthony Roberts ? - *clickhouse-connect* is available on clickhouse-connect · PyPI <https://pypi.org/project/clickhouse-connect/#files> Great push @Omair Javaid - *zopfli* is available as well: zopfli · PyPI <https://pypi.org/project/zopfli/#files> @Anthony Roberts please let me know if I missed something regardless the previous list of work you had, any other blockers you have? Feel free to nudge me more frequent. ------------------------------ *From:* 'Gleb Khmyznikov' via CoreCollective Windows on Arm *Sent:* Monday, June 15, 2026 2:38 PM *To:* Anthony Roberts ; Omair Javaid *Cc:* CoreCollective Windows on Arm *Subject:* Re: [EXTERNAL] Re: [CoreCollective WoA] Public tracker updates Thanks for investigation, I’ve sent the email to NV about cuda-bindings.

I suspect they don't want the maintenance overhead of Windows, too. If x64 Windows is also missing, I suspect this could be a decent candidate to argue doesn't need porting. tree-sitter-languages: As per their repo, the library is unmaintained (https://github.com/ grantjenks/py-tree-sitter-languages#status) - they offer an alternative there, which already has ARM64 wheels: https://pypi.org/project/tree- sitter-language-pack pyiceberg: Blocked on pyarrow cuda-bindings: We'll need to wait for the public CUDA SDK for this one, unless we're happy to use pre-release versions and not commit anything until public ones are out - are NV already working on this themselves, is it worth checking? temporalio: Worth an investigation into the build failures Omair is seeing, and what is causing them. I'll try to look into this one, assuming Omair hasn't yet. clickhouse-connect: Looks like Omair's issue spurred them into doing it, no action is required from us zopfli: Same thing, they have also done the work for the wheel to be released Thanks, Anthony On Tue, 9 Jun 2026 at 13:55, Omair Javaid wrote: HI Gleb, Thanks for this update. I created issues for some of the missing packages. See the links inline below. On Sun, 7 Jun 2026 at 04:19, 'Gleb Khmyznikov' via CoreCollective Windows on Arm wrote: Happy weekend everyone. I've updated our public <https://github.com/khmyznikov/PyEnv-WoA-State/issues/1> tracker to align with Tony tracker <https://tonybaloney.github.io/windows-arm64-wheels/>. We are at 95% completion. Missing packages added: - *sglang *- https://github.com/sgl-project/sglang/pull/19706 windows only, someone from the community initiated the support, but looks abandoned. - *tree-sitter-languages* - development looks stale. - *pyiceberg* https://github.com/apache/iceberg-python/issues/3473 - *cuda-bindings* - *temporalio* https://github.com/temporalio/sdk-python/issues/1592 - *clickhouse-connect* https://github.com/ClickHouse/clickhouse-connect/issues/785 - *zopfli* https://github.com/fonttools/py-zopfli/issues/32 Anthony, you might be interested in that since nobody took it yet for enablement. Let me know if you start something from this list. P.S. I've added crypto monitoring action <https://github.com/CoreCollective-dev/windows-on-arm-wg/actions/workflows/monitoring_cryptography.yml> to our core collective repo.
