See PRs #3413 <http://Updating EWAH from upstream lemire/EWAHBoolArray #3413> and c821824 <https://github.com/yt-project/yt/pull/3447/commits/c821824860595b4a969d9b89…> for EWAH support to fix windows builds and #3445 <https://github.com/yt-project/yt/pull/3445> for WarpX support. Binaries for yt 4.0.1 are available via pip and conda. If you installed via the install script or use conda to manage your python installation, you can update yt via: $ conda update -c conda-forge yt And via pip if you manage your python installation with pip: $ pip install -U yt As always, if you have any questions, concerns, or run into any trouble updating please don’t hesitate to send a message to the mailing list or stop by our Slack workspace. Thanks for being in the community! - the yt development team ** please note that the conda builds may be available slightly after this message.

YTEP-0040: a yt-baked colormap package
by Clément Robert 16 Jul '21

16 Jul '21

Hi yt-dev ! I wrote a small YTEP to propose that yt’s native colormaps be isolated into a lightweight independent package. See the motivation therein https://github.com/yt-project/ytep/pull/20 Although the priority for doing this is pretty low, I do think some form of change is required in this area, following the upstream change of behaviour introduced in matplotlib 3.4 Considering the task itself is also reasonably small and straightforward, I assume it is reasonable to submit it now so it may be considered for yt 4.0 (plus, I couldn’t resist submitting a 40th YTEP on Matt’s 40th birthday). A minimal goal here would be to improve our documentation to showcase the 7 (6 ?) original cmaps from the yt community. Namely: - algae - arbre - dusk - kamae - kelp - octarine - (spectral) -> this one seems to be currently broken actually, or was it just renamed ? See https://github.com/yt-project/yt/issues/3165#issuecomment-822241839 If we agree to bake a separate package out of them, I would also like to give credit to their respective creators. I know that Nathan came up with “arbre”, but I don’t know who created the other 6 (5). Please share your knowledge, I’m interested in knowing this whatever the fate of this YTEP :) Cheers Clément

ANN: yt 4.0.0 release
by Madicken Munk 07 Jul '21

07 Jul '21

Dear yt users and developers, The yt community is proud to announce the release of yt-4.0! yt (http://yt-project.org) is an open source, community-developed toolkit for analysis and visualization of volumetric data. This release features a complete reworking of a number of internal components, most importantly those related to particles and discrete points. In keeping with this, we expect that some scripts used for analysis will require modifications; information about "what's new" as well as instructions for how to update analysis scripts can be found at: https://yt-project.org/docs/4.0.0/yt4differences.html . A set of highlights of the pull requests that went into this release can be found here: https://gist.github.com/matthewturk/7a1f21d98aa5188de7645eda082ce4e6#file-h… A full listing of the pull requests that went into this release can be found here: https://gist.github.com/matthewturk/7a1f21d98aa5188de7645eda082ce4e6#file-y… This release has been years in the making, and features contributions from dozens of individuals, many of whom were new to the project. It marks the culmination of a set of wide-reaching infrastructure changes that result in much higher fidelity to the underlying data for particle datasets. At the end of this email you can find a non-exhaustive list of individuals who have contributed to this release; many of them made their first contribution during this release! Binaries for yt 4.0 are available via pip and conda. If you use conda to manage your Python installation, you can update yt via: $ conda update -c conda-forge yt If you manage your Python installation with pip, you can update yt via: $ python -m pip install -U yt For more information, including installation instructions, links to community resources, and information on contributing to yt’s development, please see the yt homepage at https://yt-project.org and the documentation for yt-4.0 at http://yt-project.org/docs/4.0.0 We especially thank Nathan Goldbaum for his many years of work and contributions to this release and to the yt community. yt is the product of a large community of developers and users and we are extraordinarily grateful for and proud of their contributions.
