The chocolatey installer for dmd is stuck on 2.100.2 as it's not been maintained in ages. There is a process for changing the maintainer of a package in this situation, documented here: https://docs.chocolatey.org/en-us/community-repository/users/package-triage-process/#the-triage-process

I asked the maintainer if they would transfer the repo over to dlang-community back in 2023: https://github.com/PxlBuzzard/ChocoPackages/issues/8#issuecomment-1786906856

It would be great if new dmd releases were made available via chocolatey as part of the release process so would someone within the core Dlang team reach out to chocolatey to take over maintenance of the package.

Well, I personally stopped using choco long ago. Instead, I use scoop, which has (git repo based) buckets with manifests, which have an autoupdate feature.
Once installed, you now and then run scoop update * and all your installed software is up2date...

To install dmd, just follow https://scoop.sh/#/apps?q=dmd :)
