Road Map for 2025 | 2025-01-22
##############################
| We dedicate the year 2025 to Genode's rigidity, clarity, and performance.
At the turn of each year, the Genode community and core developers reflect
on the past year's achievements and make up their minds about the year ahead.
The updated road map for 2025 condenses the recent brain-storming on our
public mailing list and presents a rough feature schedule for the releases
planned for 2025. Get a glimpse at Genode's foreseeable future by visiting our

Since we added
[https://genodians.org/atopia/2023-10-26-a-first-complex-rust-package - Rust support]
to the Goa tool mid of 2023, we have been looking for natural synergies
between Rust-based projects and Genode. During the road-map discussion, we
identified the use of Rust-based components as building blocks for a
multi-component e-mail client a tempting opportunity. Throughout the year, we
plan to take an (open-ended) e-mail scenario as motivator for combining our
interests in Sculpt usability, Goa-based development work flows, and Rust.
Device-wise, we will continue our engagement with the PinePhone, look forward
to the upcoming MNT PocketReform, and take on the latest Intel-based PC
platforms. We also want to explore the use of Sculpt OS on form factors like
the ZimaBlade single-board server (headless operation) or the StarLite tablet
(touch-based UI).
