I'm planning to dive into the adventure of writing articles for the community. What kind of topics would you be interested in learning about? #Android #Compose #KMP #Mobile #OpenSource

We're reworking how settings are organized in Thunderbird Desktop and would love your thoughts. Take our short survey, 10-15 minutes tops. No trick questions, no wrong answers, and your feedback goes straight to the designers. Take the survey 👇 sohub.io/wm2k #opensource #thunderbird #ux

If you've ever opened Thunderbird's settings and felt like you needed a computer science degree, you're not alone. We're rewriting 250+ settings in plain language, and the results from our user testing are in. Check out the full details on our blog: sohub.io/zxqf #opensource #thunderbird

Our July Mobile Progress Report is here! Check out our blog to see where we are with iOS development, as well as updates to the Android app. #android #ios #thunderbird #opensource blog.thunderbird.net/2026/07/mobil…

📅 Thunderbird's calendar is getting a redesign! Jesse from the design team walks through the journey so far, including modernizing the grid, navigation, and calendar sidebar. Read the full post: blog.thunderbird.net/2026/08/deskt… #thunderbird #calendar #design #opensource

I am very very excited that Gradle Isolated Projects feature is finally marked as incubating. It is time for folks to try it out and see what breaks :) docs.gradle.org/9.7.0-rc-1/r...

In case you missed it: Thundermail, our new email service, has started sending invites to Early Birds on the waitlist. Early subscribers get a real say in where our #opensource #email service goes next, and we want you along for the ride! Join the waitlist here: www.tb.pro/waitlist

One of the things we love most about our community is its passion for every detail. One of our design team recently sat down with ten of our users to learn how they use Thunderbird, and what would make using it even better! 📣 #Thunderbird #OpenSource blog.thunderbird.net/2026/07/deskt…

So, with the new tiny Maven Central limits, what are the real options for community open source projects? JitPack? Self-hosted Maven repository? Any other options? #AndroidDev #KMP #Gradle #MavenCentral

Our Thundermail Early Birds have spoken and we're listening: Webmail and two-factor authentication are on the way, as well as better support for custom domains and a smoother onboarding experience. Find out more and join the waitlist! blog.thunderbird.net/2026/06/thund…

We're adjusting our roadmaps and making better Android notifications our next stop. iOS development is on track, and we're grateful for our community contributors (and want you to know how to get involved). blog.thunderbird.net/2026/06/mobil…

How-To Geek wrote a great article about swapping Gmail's app for Thunderbird on Android: "It's a free, open-source, privacy-focused app, and it makes email feel like it used to." www.howtogeek.com/i-ditched-gma… Check out Thunderbird for Android! https://sohub.io/npmm #thunderbird #opensource

🔐 Starting with Kotlin 2.4, the standard library includes an 18-month security support policy. Security fixes will be backported to all active release lines within the support window. 👉 For more keynote highlights: https://kotl.in/rm6hir

I'll be giving a talk about Metro's internals tomorrow at @kotlinconf.com! This'll be an advanced talk that assumes familiarity with Metro, and is a sort of part 2 of my "Navigating Dependency Injection with Metro" talk last year. You can find it here: www.youtube.com/watch?v=jVfm...

Introducing Android Performance Analyzer : The Next Evolution in Profiling for Android android-developers.googleblog.com/2026/05/intr...

Last Friday, we announced a ✨ new default structure ✨ for Kotlin Multiplatform projects. (Nothing like a late Friday afternoon release!) In case you missed that, here’s a quick recap of what’s new! 🧵👇

🤖 I've just open-sourced a new set of skills, covering Kotlin, Compose and Android development. Very early days, but it covers a lot of things which crop up in code review regularly. github.com/chrisbanes/s...

scrcpy 4.0 is out 🚀 Try the new flex display feature (and more): github.com/Genymobile/s...

Our new episode of Office Hours is out! We're chatting with Thunderbird contributor Bogomil about how he got involved with the project, mentorship in the open source community and more. Check out the link to watch to the full episode! youtu.be/xSXJsPIVV60?... #Thunderbird #OpenSource

✨ New article! How to create Airbnb's beautiful month picker dial in Jetpack Compose www.sinasamaki.com/made-in-comp...

Compose Stability Analyzer 0.7.3 introduces the runtime Compoes state tracking. By adding the `TraceRecomposition` annotation to your composable function, you can trace all the parameters and in-body Compose states in the logcat. skydoves.github.io/compose-stab...

Someone just shared, out of the blue, my project on another social media! That is the first time it ever happened and I was so happy to see that! Sometimes I wonder if I should ever keep working on it, if ever people are using it or not. It felt heartwarming seeing that, tbh!

Metro is so good! If you haven't tried yet, I strongly suggest you to!! I wish IntelliJ allowed non-bundled K2 compiler plugins to contribute their FIR checkers to the IDE so we could see diagnostics in real-time. Perhaps a Metro IntelliJ plugin could bridge the gap until then

Why Compose HotSwan 🦢 It explains how Compose HotSwan brings true Hot Reload to Android, avoiding rebuilds and app restarts. It enables instant UI updates on a running app while preserving state, improving development speed. hotswan.dev/docs/how-it-...

Another tweak.

One of the biggest gems of Compose Hot Reload is the ability to simulate animation variations directly on real Android devices. hotswan.dev/docs/support...

We have a shiny new roadmap site, and an equally shiny new blog post to tell our community all about it: #Thunderbird #OpenSource blog.thunderbird.net/2026/03/intro…

Thundercast is back! Our hosts are steering us through the roadmaps for the desktop and mobile clients. Tune in for all the information on what's coming next, and minimal backseat driving. #Thunderbird #ThunderCast #OpenSource share.transistor.fm/s/4db3895e

I can't believe that I will attend KotlinConf this year 😱

I NEED THIS SO MUCH!

Today I’m open-sourcing Dejavu! Testing UI performance in Jetpack Compose is frustrating. We profile and watch tools, yet regressions still creep in. I built Dejavu to make recomposition behavior something you can actually test.

Everything's coming up roses in Pasadena for @socallinuxexpo.bsky.social! Come visit us in the Expo Hall at booth 221 to chat with our team, learn what we're up to, and grab some stickers from: 14:00-18:00 Today 10:00-18:00 Saturday 10:00-14:00 Sunday #Thunderbird #SCaLE23x

We're excited to shine a light on Michaela Martin, the design artist behind our appeal illustrations. We chat about her background, her process, and how Roc and his world went from first sketches to final drafts. 🎨 #Thunderbird #Illustration blog.thunderbird.net/2026/03/desi...

🎙️Check out the new @fragmentedpodcast.com episode on subagents! They can be a huge unlock once you understand how it all works and you can get real benefits without having to a swarm them. @kau.sh and I built an RTS mental model for how they work (yes, we did that). Check it out!

new episode is out! spot the easter 🥚? recent models have shown massive improvement owing to clever use of "modes" and subagent dispatch. it really clicked for me after chatting with @iurysouza.dev listen to improve your fundamentals! (not just tactics).

And our Mobile Progress Report provides an early look into how development on Android AND iOS (!) will take shape over the coming year. #Thunderbird #Android #iOS #OpenSource blog.thunderbird.net/2026/02/mobi...

Heads up it looks like Sonatype is starting to enforce stricter throttling on Maven Central. If you see 429/403 errors from your runneres, you're not alone. github.com/actions/runn... www.sonatype.com/blog/maven-c...
