MAINT: Release 0.21

[larsoner]

We should cut a release in a few weeks, tentatively scheduled for September 15th. Feel free to tag issues and PRs that realistically can and should make it if you have permissions, and if you don't, feel free to comment on ones that you think should be tagged for 0.21.

September 15 ? @larsoner

[larsoner]

Whoops, yes I meant Sept 15th :)

[hoechenberger]

We need to draft an announcement. Also with the last release we had this small video clip demonstrating the new Time Viewer. We should do a similar demo of some notable features in 0.21 as well. Which are the most notable new features?

[hoechenberger]

Maybe:

• muscle artifact detection ENH: muscle artifact detection #7407
• improved diploe plotting MRG, ENH: Add ori on MRI slices #8188
• allow renaming of montage channels MRG, ENH: Add DigMontage.rename_channels #7685
• volumetric atlas support MRG, ENH: Add volumetric atlas support #7639
• eSSS MRG, ENH: Add eSSS #7156
• STC flatmap MRG, ENH: Add flatmap #8082
• REST MRG, ENH: Add REST #8132
• cov.plot_topomap MRG, ENH: Add cov.plot_topomap #8197
• Persyst reading [MRG, IO] Persyst reader into Raw object #8176
• Nihon Kohden reading Nihon Kohden EEG file reader WIP #6017

[cbrnr]

Maybe mne.io.read_raw #7809 is also worth mentioning as a QoL improvement.

[hoechenberger]

From the chanelog:

• Add 'auto' option to mne.preprocessing.ICA.find_bads_ecg() to automatically determine the threshold for CTPS method by Yu-Han Luo
• Add a notebook 3d backend for visualization in jupyter notebook with mne.viz.set_3d_backend() by Guillaume Favelier
• Use PyVista as the default backend for 3D visualization instead of Mayavi by Guillaume Favelier

[larsoner]

• Volumetric 3D rendering (MRG, ENH: Volume rendering #8064)

BTW we are not ready to release, I'm still doing battle with CircleCI

[cbrnr]

@hoechenberger since we're already discussing the release, did you have time to work on an mne-base package in conda-forge by any chance? I think this would be pretty useful, because the standard package is really quite bloated if all you need is basic EEG analysis tools.

[hoechenberger]

@cbrnr Yes, in conda-forge/mne-feedstock#37
I stopped at some point, I believe there were some difficulties, but cannot remember any details! Would be happy to try picking this up again. But not before the weekend.

If possible I'd like us to start highlighting the contributions of new-to-mne developers in our release announcements. At a minimum, maybe "there were N contributions from M first-time contributors in this release cycle". Better would be to also give examples and call out their names.

[larsoner]

Maybe we should start this process by bolding the entries in the latest.inc?

[drammock]

That could work, although I wonder if folks read the whole changelog (i.e., would bolding actually increase visibility if it's not being read?)
