yt user/developer workshop in Edinburgh: 2nd announcement
by Britton Smith April 29, 2025

April 29, 2025

Registration is currently open for the yt user/developer workshop, to be held July 15-18, 2025 at University of Edinburgh in Edinburgh, UK. yt <https://yt-project.org/> is a community-driven Python package for analyzing and visualizing astrophysical simulation data, supporting output from nearly two dozen astro simulation codes and several more from other domains (see list of supported formats below). This interactive workshop welcomes researchers from all career stages to learn to use and modify yt for sophisticated analysis of simulation and general spatial data. The first two days will be devoted to tutorials starting from scratch and working toward advanced usage, including parallel computing. Participants are encouraged to bring ideas for challenging analyses they would like to undertake or samples of data not yet supported by yt. There will be opportunities to work with developers to add support for new data or develop new features. The workshop will then transition to showcasing packages extending or related to yt and learning how to modify the code and contribute to the project. We will end with a day of breakout groups working on coding projects of their choice. Participants will also have the opportunity to give short presentations on relevant research or related software packages. Registration is free and can be done here <https://higgs.ph.ed.ac.uk/workshops/spatial-analysis-across-scales-and-doma…> . All experience levels, career stages, and areas of interest are welcome. Registration will be limited to 35 people. The registration deadline is June 2, 2025. For more information, please contact Britton Smith at britton.smith(a)ed.ac.uk .

Releasing yt 4.4.0
by clement.robert＠protonmail.com Oct. 10, 2024

Oct. 10, 2024

Dear yt team I think yt is ripe for a new feature release (4.4.0), especially with the recent merge of https://github.com/yt-project/yt/pull/4939 (that will no doubt be the highlight of the release notes) Even though there are no strict blockers, there are still a couple items in the milestone that I'd like us to clear before the release; in particular: - Adding wheels for the upcoming Python 3.13 https://github.com/yt-project/yt/pull/4973 - Future proofing Cython build-time compatibility https://github.com/yt-project/yt/pull/4948 - Deciding if we want to drop support for Python 3.9 now or later https://github.com/yt-project/yt/issues/4977 See the full milestone https://github.com/yt-project/yt/milestone/30 [yt.png] [4.4.0 Milestone · yt-project/yt](https://github.com/yt-project/yt/milestone/30) [github.com](https://github.com/yt-project/yt/milestone/30) I’ve been managing the milestone as both a record and a Wishlist, not a set of hard requirements. If all goes well, I’d like to propose we publish v4.4.0 by the end of September (i.e., right before Python 3.13.0 final is out). Please let us know if there’s anything else that you’d really like to see merged before we cut the release. Thanks Clément

nominate Shin-Rong Tsai for membership
by Matthew Turk Dec. 4, 2023

Dec. 4, 2023

Hi folks, I'd like to nominate Shin-Rong Tsai as a member of the yt project. She's been working on the libyt project for in situ analysis, and has been working with me, Chris Havlin, and Corentin Cadiou on optimizing the indexing system. Just this last week she released a preliminary version of libyt jupyter, a mechanism for connecting running simulations to interactive jupyter kernels. I think she'd be a great member, and I would like to formally nominate her. -Matt

Status update & planning the next bugfix release
by clement.robert＠protonmail.com Nov. 4, 2023

Nov. 4, 2023

Hi team I wanted to keep you updated with the state of things, as this year is seeing an unusually large number of big changes in our core dependencies. - migration to Cython 3 appears to be complete, as we haven’t received reports of degraded performance since the launch of yt 4.3 - full support for CPython 3.12 is near complete, the only thing that’s missing is systematic testing with all optional dependencies, and we’re mostly just waiting for things to move upstream at this point. Here’s the tracking issue https://github.com/yt-project/yt/issues/4689 - unyt 3.0 was successfully released this week, causing *very* little breaking in yt (in fact, only a single test function still required adjustments). See my announcement on this mailing list for details. - numpy 2.0 is the next (last) big thing on the horizon now. I recommend checking https://github.com/numpy/numpy/issues/24300 for details, but the TL;DR for us is that, in order to help our users smoothly transition, we’ll need to publish a new set of binaries for yt when the first release candidate drops. Numpy 2.0.0rc1 is currently scheduled for “the end December” and should be followed by the final release about 6 weeks later. My takeaway is that, unless something critical comes up before that, or if the number of back ported bug fixes becomes too large (TBD), we should schedule our next bugfix release, yt 4.3.1, sometimes during this 6 week period, so about 2 months from now. Take care Clément

ANN: unyt 3.0.1 is now available
by Clément Robert Nov. 2, 2023

Nov. 2, 2023

We're happy to announce the release of unyt 3.0.1 ! This version (as compared with 2.9.5) brings a major improvement: the implementation of "array functions” (as defined by [NEP 18](https://numpy.org/neps/nep-0018-array-function-protocol.html)), bringing unyt more in line with astropy.units. In short, this means that a lot more of numpy functions are now unyt-aware and should behave more intuitively when passed unyt_array instances, including - np.dot - np.inner - np.histogram - np.concatenate - np.stack - functions from np.linalg and np.fft - np.isclose - and many more ! This also means that existing applications *may* break around these functions, as the return value suddendly have dimensionally accurate units they previously didn't, which is why the *major* version number was bumped from 2 to 3. Despite our efforts to make this release as stable as possible, some unintented breakage may still happen, so please report any supsicious behaviour you encounter. Another major feature in unyt 3.0 is first class support for unyt-aware dask arrays. See our documentation for details on how to use it https://unyt.readthedocs.io/en/latest/usage.html#working-with-dask-arrays Note that it isn't recommended to use unyt 3 with current yt (4.3.0), but the next yt release will be compatible with both unyt 2.9 and 3.0, so yt users will be allowed to switch back to the historical behaviour and transition more smoothly. For a more complete description of changes in this release, including bug fixes, see our changelog https://unyt.readthedocs.io/en/latest/history.html

Finalising and publishing yt 4.3
by Clément Robert Oct. 10, 2023

Oct. 10, 2023

Hi all, A few weeks back, I told you that yt 4.3 would be delayed until things got stabilised for Python 3.12, and it’s about to be the case ! Namely, the one blocking issue was a Cython bug (resolved thanks to Eric), solved in Cython 3.0.3, which should land on PyPI today. Thus, I propose we try and get this release out the door tomorrow, or maybe next week. Cheers, Clément
