WhatsApp Desktop Faces Major Update: Users Warned of Forced Logout and Resource-Hungry Upgrade

WhatsApp is preparing to log users out of its PC applications with a sweeping update set to begin on December 9, 2025. This comes as part of Meta’s plan to replace the older native Windows WhatsApp with a Chromium-based version—a move that promises new features but significantly increases system resource usage. While this is not the first warning, it signals a major shift in…

I noticed the upcoming chatmail ‘relays’ feature in #deltachat. Changing the relay in the app (version 2.33) seems really easy, fantastic!

@delta I was wondering (for a friend) if there will be any publicly available relays published as a *#tor #onion service* as well? In combination with the app’s proxy support this would be awesome for any user’s #privacy.

for Tor there is nothing immediately planned but you may checkout and follow updates on github.com/chatmail/relay/issu…

the "IM2000" description is somewhat dense and trying to account for a lot of past efforts in modifying SMTP, but the im2000 issue is just background for a mechanism that will likely be quite straightforward and simple. 😅

Was just thinking realistically, are you going to pull out your DotPad, Monarch, other larger graphic Braille display at the airport to check your Uber ride status? Or look at a transit /navigation app at directions? Was looking at the dimensions for the DotPad, the smallest of them all, and it's still the size of an iPad 11-inch, slightly larger and thicker. Good to pull out at your gate or in-flight, bad when walking around as it's too large.
Some of you have asked if Cadence uses a membrane or film over dots, and the answer is no. I'm told this was a deliberate choice, to make the cells feel more crisp and sharp. Indeed, their rigidity reminds me of Orbit cells, but you can push down on them and when you lift your finger they spring back up. While you lose out on uninterrupted graphics (since Cadence uses Braille spacing, meaning there's a gap every 2 columns,) you get a pocketable reading device that's prioritized for that task. I was thinking to myself how most of these companies approached the multiline Braille concept purely from the graphic side, not so much making reading portable. For many of these companies Braille is another product alongside magnifiers or screen readers, or big-name medical groups sponsor them. (Dot Inc is an exception here.) So they didn't have the creativity to think, "what if we made smaller versions of this? 4 lines of 12 or 20?" Still find this a bit astounding and sad, until Cadence came along. They took a lost opportunity and made it real.

Informal Masto poll: What do y’all think of the name Nayshawn? Pronounced ‘Nay Shawn.’ For context, I was telling my s.o earlier that if we were to have a kid, I would want them to have a name that doesn’t get them picked on in school. And, he was like, if it’s a boy, we should name him Nayshawn. I think this name is ridiculous. He thinks it’s kick-ass. What do you think, fediverse folks?

#deltachat PSAs regarding the last 24 hours:

1) If you messaged someone about 20-30 hours ago, and did not get an expected response/receipt better "resend" (long-tap or right-click the message to resend). Unfortunately, not all queued messages at the crashing nine.testrun.org server made it to the new one.

2) 2.33+ app releases are rolling out, supporting using "multiple relays" so that failing relays (like happened above) will not cause lost messages anymore. See support.delta.chat/t/how-to-mi…

in reply to devSJR

there is a blog post coming. bear with us :)

but roughly the current first multi-relay release introduces the ability to have more than one relay associated to your chat profile. You can choose what is your primary device, but will receive messages also on all secondaries. This is just an intermediate step towards another release where the outcome will be: if any relay works, the message will get through. single relays failing don't matter.

@devSJR yes, that's the plan that you can exit from gmail or other big providers if you started with them. It's just that the last weeks were a lot of work for everyone involved, and we still need to stay attentive/co-ordinate about any issues in conjunction with rolling 2.33 releaeses (it's more complicated than you might think). Originally, we only wanted to publically talk/educate about it when the releases are fully available for people. Maybe just check back next week :)
in reply to Delta Chat (39c3)

You are certainly right when you say “it's more complicated than you might think”. I am fine with waiting.

BTW, I always like these non-noisy updates. The last one included "calls" which is a big deal. However, it seemed to have the same importance as “we fixed this one bug that affect one person in a hypothetical scenario”. In this release, there is yet another big feature.

Keep up the good work.

The first article in one of our national newspapers this morning about the launch of the European Digital Infrastructure Consortium (#EDIC) today 🍾🇪🇺

Title: "Europe takes first step towards digital independence. Four European countries are taking on the American tech giants, taking the lead in developing European software." 🇳🇱🇫🇷🇩🇪🇮🇹

Seufz, da ziehe ich vor einigen Monaten aus Gründen meine Podcasts endlich zu einem deutschen Podcast-Hoster um, bin aber mit der Oberfläche in vielen Belangen nicht wirklich glücklich. Außerdem ist das Modell so, dass ich den zweithöchsten Tarif buchen musste, ohne wirklich alle Features zu brauchen. Und dann spült mir heute Morgen bei einer Diskussion auf FB ein Bekannter den Tipp zu @letscastfm in meine persönliche Wissensdatenbank. So ein sympathischer erster Eindruck! CC @quentara
in reply to Marco Zehe

Ich bin tariflich jetzt auf jeden Fall bis September kommenden Jahres festgelegt bzw. habe das schon bezahlt, ich werde aber definitiv mal einen Testpodcast bei @letscastfm starten, um zu testen, wie mir die Oberfläche des Backends gefällt und diese mit Screen Readern zusammenarbeitet. Die Website selbst macht schon mal einen guten Eindruck. Und wenn's mir gefällt, ziehe ich die Podcasts eben nochmal um. ;-)
in reply to Marco Zehe

Danke Dir, lieber @marcozehe 😊 Wir freuen uns, dass Dir der erste Eindruck gefällt, und hoffen, dass Dein Test dem in nichts nachstehen wird.

Bislang haben wir positives Feedback von Menschen mit Sehbeeinträchtigungen zur Nutzung mit Screenreadern erhalten. Wir lernen aber gerne weiter dazu. Solltest Du also Feedback oder Fragen haben, lass uns das gerne zukommen.

in reply to Marco Zehe

Ich habe jetzt mal einen Account und einen ersten Podcast bei @letscastfm eingerichtet, aber noch keine Episode hochgeladen. Das kommt im nächsten Schritt. Die Tabs pro Podcast oder so sind zwar technisch noch nicht richtig ausgezeichnet, konzeptionell aber gut erreichbar, und vor allem ist das mit Überschriften alles schön aufgeteilt, sodass ich schnell zu den richtigen Bereichen der Seite komme. Bisher gefällt's mir gut.
in reply to Marco Zehe

So, und das ist meine Nullnummer. ;-) Noch habe ich sie bei keinen anderen Podcast-Diensten eingereicht, das kommt dann im nächsten Schritt. Bisher bin ich auf keine nennenswerten Barrieren gestoßen. marco-erzaehlt.letscast.fm/epi…
in reply to Marco Zehe

Und jetzt ist der Podcast zumindest schon mal bei Apple und Spotify angemeldet. Und natürlich gibt's auf der Seite auch den RSS-Feed zum Abonnieren. marco-erzaehlt.letscast.fm/
in reply to Marco Zehe

Nach viel Kopieren, Einfügen und anderem Jonglieren von Daten habe ich inzwischen diverse weitere Dienste hinzugefügt. Bei keinem Punkt bin ich auf Barrieren gestoßen, die Anleitungen für jeden unterstützten Dienst sind sehr eindeutig und geradlinig. Unten auf der Seite sind jetzt viel mehr Dienste zu finden: marco-erzaehlt.letscast.fm/
in reply to Marco Zehe

gefällt mir so gut, und die @auphonic Integration läuft so prima, dass ich jetzt vorzeitig meine beiden anderen Podcasts umgezogen habe. Ob ich das jetzt mache oder erst kurz vor Ablauf der Laufzeit beim alten Hoster, ist ja gehüpft wie gesprungen, wie man bei uns so sagt. Auch die Verdrahtung mit den Ausspielern scheint soweit gut zu laufen. Nur Spotify und YouTube Music brauchen wirklich Handarbeit, weil sie den 301 Redirect ignorieren. Aber auch das lief gut. Happy Podcaster. :-)

Two things I want for Christmas, but which probably don't exist. 1. A wireless keyboard as much as possible like the Logitech G613, all 104 keys, but it doesn't have the palm rest or the macro keys going down the left side. 2. Sennheiser Ambeo binaural ear/microphones, but rather than working with an iPhone with a Lightning port, they have two mini (3.5 millimeter) plugs, one for the earphones, the other for the microphones.

the g in gobject stands for glib, and the g in glib stands for gtk, and the g in gtk stands for gimp, however the g in gimp stands for gnu, so really the g in glib stands for gnu, but you shouldn't confuse it with gnulib, which is developed by the gnu project, who shouldn't be confused as the developers of glib, which is the gnome project, in which the g also stands for gnu
