Raspberry Pi OS has undergone a significant desktop redesign, coinciding with rising memory costs that have reignited debates over firmware-enforced RAM upgrade restrictions.
Despite the company not prominently displaying version numbers in its official documentation, the updated operating system’s boot screen identifies the release as version 6.3, dated September 2026. Comprehensive release notes detailing the modifications are available on the project’s long-running documentation pages.
The graphical user interface receives a substantial update this time around. Replacing the classic Windows-style taskbar is a new dock positioned at the bottom of the screen alongside a full-screen application launcher. Users are presented with three configuration choices: a dock only, a taskbar only, or both simultaneously. When both are selected, the panel adopts a transparent design and fades from view, leaving only the status indicators visible on the right side.
Testing the available configurations revealed a missing feature: the inability to position the dock vertically. A vertical layout remains the preferred arrangement for many users. Those wishing to preserve vertical screen real estate can utilize the raspi-config command to switch from Wayland to X11. While this disables the Raspberry Pi Connect feature, it restores the traditional vertical LXDE taskbar.
The new interface appears visually appealing and likely aims to reduce intimidation for younger users more accustomed to smartphones than traditional desktop environments—a demographic that remains crucial for the Raspberry Pi’s target audience.
Beneath the surface, the Wayland desktop components have been updated to “labwc and wlroots version 0.20,” according to the release notes. This trails slightly behind labwc compositor version 0.20.2, a pre-1.0 release that continues to draw skepticism from FOSS analysts who expect Wayland to have already achieved enterprise maturity.
The underlying Linux kernel remains unchanged at version 6.18, which was introduced in the previous update covered in June.
Raspberry Pi OS remains lightweight and responsive, though it lacks the sleekness of its earlier iterations. Hardware pricing continues to be steep; an 8 GB Raspberry Pi 5 previously cost £168 in the UK or $175 in the US as noted in June. Unfortunately, prices have not improved. The 16 GB model currently costs £292.80 in the UK or $305 in the US.
RAM Upgrades Encounter Firmware Restrictions
Earlier this month, Mike Thompson, the original creator of Raspbian, took to social media to express his frustration. “When I created Raspbian for the Raspberry Pi, I was excited to help bring low-cost compute into the hands of a next generation of tinkerers and programmers,” he stated. He continued, “However, I now despair that a Raspberry Pi can cost upwards of $300 because AI shortages are making personal computing unaffordable. Furthermore, bright young people are being discouraged from learning programming because they are being told it is a commodity skill that AI will do.” He concluded, “I have to ask myself what it was all for. Is this the future we were promised? If so, I’m starting to regret my part in it.”
His frustration is understandable. Such high prices create a strong incentive to repair a faulty unit or upgrade a lower-specification model using RAM salvaged from another device. However, this requires significant skill and determination, as it involves desoldering the board’s ball-grid-array system-on-a-chip and the memory chips underneath before resoldering them—a highly non-trivial task.
With the release of Pi OS 6.3, attention shifted back to a forum post made in June by Raspberry Pi Senior Principal Software Engineer Phil Elwell. He confirmed that newer firmware locks devices to their original RAM capacity.
“We therefore remove the commercial incentive by locking devices to their original RAM size,” Elwell wrote. “And for improved compatibility with a variety of suppliers, we now also program in some other device attributes, meaning that switching parts of the same size may not work. I don’t see RAM being swapped between authorized devices of different sizes as a likely use case, but don’t waste your time trying – it won’t work.”
Several reports have covered the issue this week, but a particularly insightful analysis comes from the hardware-hacking site Hackaday. Writer Arya Voronova points out that anyone capable of physically replacing the RAM should also be capable of downgrading to an older bootloader that does not enforce the firmware check. Some unscrupulous resellers appear to be buying low-memory Pi boards, upgrading them, and reselling them as higher-capacity models. Voronova discovered 15 GitHub reports from affected individuals, highlighting one case where a board with 8 GB of functional RAM identifies itself as a 2 GB board, and another where the vendor denied the modification.
The firmware check was introduced two years ago. Voronova observed that the release notes for that specific bootloader omit the change entirely. One might assume that a new verification mechanism capable of preventing modified hardware from booting would be deemed worthy of mention.
Her summary is difficult to refute: “Don’t lament Raspberry Pi RAM upgrades, especially given they’re only slightly harder to perform now. Very few hackers ever performed them, the main audience for them turned out to be dodgy hardware resellers online, and in most cases, repair doesn’t seem to be impeded at all, either.” ®
