Pop!_OS 24.04 LTS released

Version 24.04 LTS of the Ubuntu-based Pop!_OS distribution has been released with the COSMIC Desktop Environment: Today is special not only in that it's the culmination of over three years of work, but even more so in that System76 has built a complete desktop environment for the open source community. We're proud of this contribution to the open source ecosystem. COSMIC is built on the ethos that the best open source projects enable people to not only use them, but to build with them. COSMIC is modular and composable. It's the flagship experience for Pop!_OS in its own way, and can be adapted by anyone that wants to build their own unique user experience for Linux. In addition to the COSMIC desktop environment, Pop!_OS is now available for Arm computers with the 24.04 LTS release, and the distribution has added hybrid graphics support for better battery life. LWN covered an alpha version of COSMIC in August 2024.

Pop!_OS 24.04 LTS Released with New COSMIC Desktop

Pop!_OS 24.04 LTS is available for download, the first version of the Ubuntu-based Linux distribution to use System76’s all-new Rust-based COSMIC desktop environment. It’s been a “long ride” to get here (building an entirely new Linux desktop, compositor, widget toolkit, and suite of first-party apps is no mean feat). System76 announced plans to build COSMIC in 2021, and a series of alpha and beta builds followed. Now, it’s out in orbit, joining the constellation of Linux distros (cheesy, eh). Carl Richell, Founder and CEO of System76, says the company is “proud of this contribution to the open source ecosystem”, and […]

Thunderbird 146 Update Migrates Logins to AES + More

MZLA Technologies Corporation has released Thunderbird 146, the latest monthly update for its famed open-source email client. Changes this month may sound less flashy compared to last month, which saw Thunderbird 145 add Microsoft Exchange support (albeit with some caveats, carveouts and a couple of capabilities still be added). Plus, work on readying Thunderbird Pro, the paid-for subscription-based webmail, appointment and file sending service excepted to cost upwards of $9/m, for a soft-launch continues. Those services are about to enter community testing. What’s New in Thunderbird 146? MZLA say logins are migrated to a more modern AES encryption standard in […]

[$] Toward a policy for machine-learning tools in kernel development

The first topic of discussion at the 2025 Maintainers Summit has been in the air for a while: what role — if any — should machine-learning-based tools have in the kernel development process? While there has been a fair amount of controversy around these tools, and concerns remain, it seems that the kernel community, or at least its high-level maintainership, is comfortable with these tools becoming a significant part of the development process.

Ubuntu’s New Telemetry Tool ‘Phones Home’ Monthly

Changes are afoot for Ubuntu’s opt-in, anonymous system telemetry gathering , including greater transparency with the open-sourcing of the server it’s sent to. Ubuntu 25.10 introduced Ubuntu Insights, a newer, more modern hardware metrics reporting service that is preinstalled alongside the distro’s existing Ubuntu Report tool. The former is used by those who upgrade to 25.10, the latter on new installs. With 26.04 LTS coming, Canonical would like to make Insights the default for all users, including those coming from versions with Ubuntu Report (i.e., Ubuntu 24.04 LTS), and re-seek consent. Telemetry makes folks twitchy so, lest anyone brandishes a […]
