Ubuntu Phone engineer reunion over a decade-old bug closure

A decades-old bug on Ubuntu’s Launchpad marked as invalid at the weekend led to an impromptu reunion for many of Canonical’s former engineers. Bug #1589796 was filed in 2016 by a user who’d spent £700 on Ubuntu phone and tablet hardware but, on visiting the official website, found no documentation to tell him how to use them. Canonical axed the Ubuntu Phone project in 2017, leaving this bug unresolved. Until now. Adolfo Jayme Barrientos, on the Ubuntu bug triage team, marked the bug invalid this weekend, closing it with a comment to explain (nearly a decade late) that phone “efforts […]

Postcard is a new email client for GNOME, built with AI

Postcard is a new email client for GNOME sporting a modern design reminiscent of Geary. The app is the work of a solo developer, gxanshu on GitHub, who is upfront about using AI coding tools to bring this “modern mail client” to life. Postcard is written in Python with GTK4/libadwaita. It uses imaplib and smtplib for networking, a local SQLite index for searching, WebKitGTK for rendering HTML and libsecret for keeping passwords safe. It’s also open source, so the code is inspectable. Visually, Postcard should look familiar to fans of the Geary email client, as it uses a similar multi-column design: folders […]

Thunderbird 154 Released with System Tray Mode, Microsoft Graph Support, and Major Mail Fixes

Thunderbird 154 Released with System Tray Mode, Microsoft Graph Support, and Major Mail Fixes

The Thunderbird team has officially released Thunderbird 154, delivering several useful new features alongside a substantial collection of fixes for email, calendars, address books, authentication, and stability. Released on August 18, 2026, Thunderbird 154 is now the latest monthly release of the popular open-source email client.

For Linux users, one of the most interesting additions is a new optional system tray mode, while Microsoft 365 users gain Microsoft Graph support. The release also improves global search, attachment handling, IMAP reliability, Exchange authentication, and CalDAV synchronization.

New Optional System Tray Mode

One of Thunderbird 154’s most welcome additions is an optional system tray mode.

When enabled, closing Thunderbird’s last window no longer needs to completely terminate the application. Instead, Thunderbird can remain running in the background through the system tray.

This can be particularly useful for users who want Thunderbird available throughout the day without keeping its main window open.

For Linux desktop users, the feature could make Thunderbird feel more like a traditional background email client, especially on desktops where tray-based applications remain part of the normal workflow.

Microsoft Graph Enabled for Microsoft 365

Thunderbird 154 also enables Microsoft Graph for Microsoft 365.

Microsoft Graph is Microsoft’s API platform for accessing Microsoft 365 services and data. Its integration is particularly important as Thunderbird continues improving its support for Exchange and Microsoft-hosted email environments.

Thunderbird has been steadily expanding its Microsoft ecosystem compatibility, making the open-source client increasingly practical for users who need to access workplace Microsoft 365 accounts from Linux.

Global Search Gets a Useful New Option

Thunderbird’s global search functionality also receives an improvement.

Users can now configure global search results to open in list view by default, providing another option for people who prefer a more traditional message-list workflow when reviewing search results.

It’s a relatively small addition, but one that can make repeated searches more convenient for users managing large mailboxes.

Better Attachment Management

Thunderbird 154 introduces several improvements for handling email attachments.

A new “Copy To” folder context menu has been added for message/rfc822 attachments, and these attached messages can now be dragged directly into Thunderbird’s folder tree.

These changes should make it easier to organize attached email messages without having to use additional steps or workarounds.

GIMP is (finally) working on a new project file format

GIMP mascot Wilber on a paper documentA new project file format is in the works for GIMP, as the existing one can’t handle larger, complex projects. Since 1997, the famed FOSS image editor has used the binary .xcf format to save projects so layers, effects and anything else can be edited and adjusted again – which doesn’t happen in a flat file export to JPEG or PNG. But, writing in a recent development update, the team has said it’s finding “more and more limitations” in the current format. And with major new features, like animation and multi-page documents, on GIMP’s near-term roadmap, it’s begun working on a […]

Dynamic icons GNOME extension adds 2 new styles, Yaru fixes

Ubuntu Dock with dynamic clock, weather and calendar iconsYou can bring Ubuntu’s clock, calendar and weather app icons to life with the Dynamic Calendar, Clocks and Weather Icons [Reborn] GNOME Shell extension – which has been updated with new icon styles. The extension already has Yaru, Adwaita, Paprius, Big Sur and other icon styles built-in (the dynamic versions don’t depend on the icon sets themselves), so you see real-time clock, date and weather info on icons that look like their static equivalents. Two new icon choices land in latest update, v9, released this week (17 August 2026), Stylish and Pure: In the screenshot above, you can see how […]

Tuba 0.11.0 released with full Mastodon quote support

Tuba app icon on a background grid of Mastodon logosA big update to Tuba, the GTK4/libadwaita Fediverse client, has landed – along with an experimental version for Android. Tuba 0.11.0 is the first major update to the social app in a year and brings full support for Mastodon quotes. Quoting posts, whether others can quote your posts and revoking consent from those who have are all supported in the composer. While the app had offered it own approach to “quote tweet” sharing of other people’s posts, support for Mastodon’s “consent-based” version means you quote respecting the needs of other users of the decentralised social media site Mastodon Collections are […]
