Next Mitsuba release / Building custom wheels

[LaVieEstDure]

Hello, I was just wondering when the next mitsuba release is planned to be made. I'm interested in distributing mitsuba into pip installable .whls that have some changes that have been made since the last official release in Feb.

I tried forking mitsuba and just running the Github actions already on the repo to try build wheel artifacts: I played with a few different commits between now and March including the current master but all of GH Actions runs have had compilation issues (e.g. this run here https://github.com/appearance-aware/mitsuba3/actions/runs/16540167502). If the release isn't soon, I'm wondering if there's a known recent commit that is known to pass the wheel build stage.

Hi @LaVieEstDure

We don't have fixed timeline, so I can't tell you exactly when we'll push out the next release. There have indeed been quite a few changes since the last release, and there still are a few more changes that we'd like to merge/do before we push out a release. If I had to say a date, maybe in a month? But don't hold me up to this.

I had a quick look at the logs you sent. Nothing came to mind when seeing those compilation errors. The build process for wheels is quite a bit different from how local builds are done, so maybe we forgot to update the former. We only really update the wheel building process right as we're about to push a release.

@njroussel Thanks for the reply! Is there a way to build the wheels with the local process? If so, is there any documentation for it?

Sorry if my answer was confusing, by "local build" I meant following these steps: https://mitsuba.readthedocs.io/en/stable/src/developer_guide/compiling.html. That process does not create a wheel.
