What is CP2K?

CP2K is rebuilding a legacy Fortran DFT code around GPUs, ML potentials, and k-points

CP2K ships twice a year and each release lands a wide slate of quantum-chemistry methods rather than a single headline feature. The last two years have been dominated by three parallel threads: pushing k-point support into methods that were previously gamma-point only, wiring in external machine-learning and GPU libraries, and modernizing the build. The 2026.2 release is the first where GPU work reaches the exact-exchange hot path and where grand-canonical SCF opens electrified-interface simulation.

What is OSRM?

A routing engine spending its release budget on the toolchain, not the router

OSRM ships frequently — nine releases in three months — but the changelogs are commit lists dominated by dependency bumps, CI plumbing, and a systematic C++20 concepts migration replacing legacy SFINAE patterns. Genuine routing changes are rare and small: an access=unknown reclassification in the car profile, a laterite surface type, a contractor self-loop correction. Several releases exist only to fix the Docker release workflow.

CP2K is rebuilding a legacy Fortran DFT code around GPUs, ML potentials, and k-points

◆ Current state

CP2K ships twice a year and each release lands a wide slate of quantum-chemistry methods rather than a single headline feature. The last two years have been dominated by three parallel threads: pushing k-point support into methods that were previously gamma-point only, wiring in external machine-learning and GPU libraries, and modernizing the build. The 2026.2 release is the first where GPU work reaches the exact-exchange hot path and where grand-canonical SCF opens electrified-interface simulation.

◆ Where it's heading

The code is converging on a plugin-heavy architecture: DeePMD-kit, NequIP, DFTD4, SIRIUS, greenX, GauXC and now libGint all arrive as external libraries CP2K orchestrates rather than reimplements. Build modernization finished on schedule — the Makefile was deprecated in 2025.2 and deleted in 2026.1 — and the same discipline is visible in the steady removal of superseded modules. Method coverage is being made uniform across periodic and molecular paths, with k-points the recurring gap being closed release after release.

◆ Prediction

Expect 2027.1 to continue the k-point sweep into the remaining gamma-point-only analyses and to broaden libGint's CUDA exchange beyond its initial path. The release notes flag FFTW3 as a likely hard dependency, so the next breaking change is probably build-side rather than scientific.

A routing engine spending its release budget on the toolchain, not the router

◆ Current state

OSRM ships frequently — nine releases in three months — but the changelogs are commit lists dominated by dependency bumps, CI plumbing, and a systematic C++20 concepts migration replacing legacy SFINAE patterns. Genuine routing changes are rare and small: an access=unknown reclassification in the car profile, a laterite surface type, a contractor self-loop correction. Several releases exist only to fix the Docker release workflow.

◆ Where it's heading

This is a codebase being modernized rather than extended. The SFINAE-to-concepts sweep across partitioner, extractor, and util, the Alpine-to-Debian Docker base swap, and the move to Ubuntu 26.04 with clang-format-22 all point at reducing maintenance drag on an engine whose routing semantics are already settled. New surface area is arriving at the edges — ARM Linux bindings, an --output option on the preprocessing tools.

◆ Prediction

The concepts migration looks close to complete, so expect the remaining refactor releases to taper and profile-level corrections to become the main visible change.
