🚨 Attention Flatcar users: We're deprecating cgroups v1 to enhance performance and security. Transition to cgroups v2 to stay updated. For more details, visit our release notes: www.flatcar.org/releases
A popular meme featuring Bernie Sanders outdoors in winter, wearing a beige parka and glasses, with a serious expression. The text at the top reads 'Flatcar maintainers:', and below, in bold white letters, it says, 'I am once again asking please note CGroups V1 deprecation.' The meme humorously references the frequent reminders about the deprecation of CGroups V1 in Flatcar Linux.

A meme featuring a scene from South Park, where a suited banker is sitting at a desk with a computer. The top text reads, 'OPENSSH CVE DISCLOSED,' and the bottom text says, 'AAAAAND ITS GONE.'

🚀 New Blog Post Alert! 🚀 We had an incredible time at #FOSDEM2025! From showcasing Gentoo on an Amiga to engaging with the OS community, it was an unforgettable experience. Read abbot our journey and 🐧 www.flatcar.org/blog/2025/02...
A four-panel *expanding brain* meme humorously escalating levels of involvement at FOSDEM (Free and Open Source Software Developers' European Meeting). 

1. **First panel**: A dimly lit brain, representing the basic level of engagement, with the text: *"ATTENDING FOSDEM AS PARTICIPANTS."*  
2. **Second panel**: A slightly more illuminated brain, symbolizing increased involvement, with the text: *"PRESENTING A TALK AT FOSDEM."*  
3. **Third panel**: A glowing brain, signifying an even greater level of dedication, with the text: *"HOSTING A SHARED FLATCAR AND GENTOO BOOTH AT FOSDEM 2025."*  
4. **Fourth panel**: A fully expanded, radiant brain, implying the ultimate level of mastery, with the text: *"DEMONSTRATING GENTOO RUNNING ON AN AMIGA AT THE BOOTH, ATTRACTING SIGNIFICANT ATTENTION."*  

Each stage suggests increasing levels of involvement, culminating in a niche but impressive technical feat that draws admiration from FOSDEM attendees.

Welcome back from Thanksgiving! We're all back at work and on our #MemeMonday game.
Painting of a 1950s scene. Husband looks up at wife, who is lighting his pipe. She says "Darling, I heard Flatcar is now a CNCF incubating project, enabling a fully community-driven cloud native stack for securely deploying containers.". He says "Well, that's nice, dear."
