New blog post: a recap of our latest hackathon, naPLari in Krakow, Poland, this past July! Read why our hackathons are world famous! (With GloBIAS, we've had attendees from every continent except Antarctica!) And give us a follow to make sure you don't miss the next one! napari.org/island-dispa...

Surface layers can now be sliced in 2D, including with thick slicing! This makes it possible to navigate surface data in the 2D view, and supports thick slicing and async slicing, allowing support for large surface layers.

You can now take a guided tour of the viewer! This is a great way to get your colleagues started with using napari. Spread the word! 😉 Access the tour from the Help menu, or using the Command Palette (Ctrl/Cmd+Shift+P).

Another long-standing issue fixed: for all of napari's history, you could only change settings on a single layer. No more: common controls now show for any selection of layers, and you can then adjust them together! 🤯

napari @napari.org · 26/08/2026

Using the same infrastructure, you can now just add @xarray.bsky.social DataArrays as images to napari and napari will read the axis labels, scale and translate, and units metadata automagically! This was issue number 14 in the napari repo. We get to stuff eventually! 😅

napari @napari.org · 26/08/2026

First up: if you add axis_labels to your layers, they will automatically propagate to the viewer! This makes it easier to reason about high-dimensional data, as shown by our friendly FLIM ghost! (Source: www.ebi.ac.uk/biostudies/b...) Check it out yourself with: gist.github.com/jni/d188d977...

Sizzling Summer Series 2: Minneapolis -> Kraków ✈️ We talked, tutorialed and sprinted at EuroPython! The sprints WENT OFF -- 22 merged PRs don't lie 🤯 Then rinse repeat for EuroSciPy - our first conference as platinum sponsors! 💐THANK YOU💐 to those who joined us in Kraków!

July was a whirlwind 🌪️ Join us for a Sizzling Summer Series of posts highlighting the community's amazing work💪 First, @timmonko.bsky.social, @aganders3.bsky.social and @willingc.bsky.social took on Minneapolis for SciPy 2026 with a tutorial, talk and plenary update - bit.ly/napari-scipy26

And it's a wrap! The hackathon was a fantastic success! 🥳 You can look forward to a longer post about all we did, and one of our biggest releases yet in 0.9.0! Huge thanks to all the participants 🤩, and we hope to see you at the next one!

Speaking of annotation: if you've switched back and forth between annotating in 2D and checking your work in 3D, you know it can be disorienting! You can now sync the 2D and 3D cameras so that panning, zooming, and scrubbing around in 2D affects 3D view, and vice versa. Let us know if it helps you!

250

napari @napari.org · 12/07/2026

Annotating blobs just got easier with auto-fill of labels when right-clicking! Right click, draw your shape, and the whole shape gets auto-filled. This should give much faster annotations for many workflows!

napari @napari.org · 12/07/2026

*Finally*, napari gets a built-in histogram! It's still a work in progress but already *very* cool if we do say so ourselves, with live update based on the canvas and progressive, background update when computing on large full data.

napari @napari.org · 12/03/2026

We would especially like feedback on: 1. Using napari with python 3.14 and the new Qt6 default backends (included in napari[all]) 2. The behavior of the new layer buttons changing how metadata is inherited 3. And trying out the new unit-aware rendering

Longer wrap-up to come, but in the meantime: we had a fantastic and productive time at the napari hackathon at @globias.bsky.social 2025 conference! Thanks to all the participants and to the GloBIAS team for hosting us!

napari 0.6.5 is out! 🚀 Rapid-fire highlights are: colorbar overlay, custom startup script, and better and prettier documentation! Check out the full release notes here: napari.org/dev/release/...

Ok guys **nobody open any more issues** 😂

Contributing to open source can be scary, but don't worry! We ourselves often write code where the initial implementation is not the best, but we are here to help simplify life. Want to know more about contributing or have anything else napari you want to discuss come join our community meeting!

napari @napari.org · 06/05/2025

Like what you see? Our own Lorenzo Gaifas is working on multichannel grid mode which is to replace our current grid mode. If you want to come discuss this or other things, join us at the community meeting tomorrow May 7th, 5:30PM CET | 8:30AM PDT at lnkd.in/gDmtK2JQ. Agenda here: lnkd.in/gna9YF8u

As a final treat, here's a video of napari 0.6.0 browsing a gorgeous 88Mp image from @noirlabastro.bsky.social (noirlab.edu/public/image...)

@czaki-pl.bsky.social has made huge improvements to the Shapes layer, supported by a grant to the Spatial Data team by @cziscience.bsky.social. We've launched a *fast* triangulation library written in Rust (called bermuda 😉), making Shapes up to 200x faster! Read more: napari.org/stable/guide...

Axis praxis! You can now point the depth, vertical, and horizontal axes any which way! We've fixed the handedness of the 3D view — DNA helices are again right-handed 😅, and if you have map data you can make latitude point north. Check out our new guide! napari.org/stable/guide...

0.6.0 features @liu-hanjin.bsky.social's command palette. It exposes all commands registered with the napari app-model (app-model.readthedocs.io/en/latest/) — including plugin commands! We now go to an exciting new phase for napari plugins — see discussion at github.com/napari/napar... for a teaser!

120

napari @napari.org · 23/04/2025

BIG change since 0.6.0a1, the culmination of months of work: we've made major improvements to triangulation (splitting polygons into triangles for drawing on the GPU), resulting in up to 200x while improving accuracy. We can now accurately draw South Africa with its enclave Lesotho.

Hello all, Hopefully the last community meeting now before 0.6.0 lands 😅 This has been a lot of hard work the last weeks by multiple people! Want to discuss the release or have any napari questions for core devs or want to show a cool demo? Come join tomorrow! Details below

130

napari @napari.org · 11/04/2025

Did you notice that cool new camera parameters menu? That and other right-click menus are easier to discover thanks to new core dev (!) @timmonko.bsky.social — check the little indicators! *And*, check the cute new canvas dimensionality toggle! And did you notice view angle is preserved now? 😉😍

napari @napari.org · 11/04/2025

What do structural biologists and atmospheric scientists have in common? They care which way their axes point! In napari 0.6.0, we finally default to a right-handed reference frame in 3D. But don't panic, we also let you customise axes directions from the API, UI, or startup preferences!

Screenshot of the napari viewer displaying the structure of B-DNA. The helix is right-handed, correctly, and the axes form a right-handed reference frame. There is also a panel that can be used to change the direction of axes.

Thanks to @liu-hanjin.bsky.social, napari now has a command palette! 🎨 This thing is really nice to use — the core team can no longer live without it — and it even works with plugin commands! 🤩

121

napari @napari.org · 08/04/2025

Our Atlantic community meeting is tomorrow, April 9, 5:30PM CET / 11:30AM ET / 8:30AM PT. This time among others we will discuss bringing the web to napari (see the very rudimentary initial example below)!

101

napari @napari.org · 31/03/2025

Another community contribution! Taking screenshots of regions of interest has been made a lot easier with help of our community member Sesan Ajina! Here, a code example: napari.org/dev/gallery/... Soon, more on how we are making publication ready figures easier with help of our community members!

napari @napari.org · 25/03/2025

Hello all, We are now very close to landing 0.6.0. Here is your last chance to give feedback and report your issues at the community meeting at March 26, 8:30am SFO / 11:30am DC / ⚠️ 3:30pm London / 4:30pm Paris ⚠️ . Agenda: hackmd.io/BXWDZ3i8Q6OA... Zoom link: numfocus-org.zoom.us/j/8404893

napari @napari.org · 20/03/2025

Gearing up for our 0.6.0 release, it is time to look back on some of the awesome features implemented by contributors of the community since 0.5.0. First off an awesome contribution by GitHub user #beanli161514 to enable 3D picking with the perspective camera with a very nice example!

0133

napari @napari.org · 12/03/2025

Please hold while we ready the 0.6.0 release… 😅
