🧑‍🚀 A new nightly version has been released! 🧑‍🚀

See the quickstart guide for installation instructions: [Quickstart | Modular](https://docs.modular.com/max/get-started/#set-up-your-project)

MAX changelog updates:

- Fixed slow `axis=None` reductions (`mean`, `sum`, `prod`, `max`, `min`) in  
`max.experimental.functional`. The previous implementation flattened the  
tensor before reducing, serializing the work onto a single GPU block.  
Reductions now iterate axis-by-axis to preserve parallelism.

- Added experimental `max.experimental.distributed` module with `DTensor`,  
`DeviceMesh`, and placement types (`Replicated`, `Sharded`, `Partial`) for  
expressing how tensors are distributed across multiple devices. Op dispatch  
is not yet supported.

- `max/python/max/benchmark/benchmark_throughput.py` has been deprecated and  
will be removed in a future MAX release.

- Added GPU kernel examples from the _Programming Massively Parallel Processors_  
(PMPP) textbook covering reductions, scans, histograms, sorting, sparse  
matrix operations, graph algorithms, convolutions, FlashAttention, and more.

Mojo changelog updates:

- [stdlib] Add `IterableOwned` trait.
- [Docs] Move rebased changelog entries from nightly to v0.26.2
- [stdlib] Relax `external_call` return type to `RegisterPassable` (#80375)
