 # Changelog
 
+## Quantum Mobile v26.03
+
+### Highlights
+
+✨ **ARM64 / Apple Silicon support.** Quantum Mobile now builds and runs natively on ARM64 hardware (Apple Silicon Macs, ARM64 Linux).
+NWChem, Quantum ESPRESSO, Yambo, Siesta, and Wannier90 are available on both `x86_64` and `aarch64`.
+ABINIT, BigDFT, CP2K, and Fleur remain `x86_64`-only for now (pending conda-forge feedstock support).
+
+📦 **Updated simulation codes.** All codes updated to their latest conda-forge versions, with explicit dependency pins for reproducible builds:
+
+| Code | Version | libxc | MPI |
+|------|---------|-------|-----|
+| ABINIT | 10.0.3 | 4.3.4 | mpich 4.3.2 |
+| BigDFT | 1.9.5 | 4.3.4 | mpich 4.3.2 |
+| CP2K | 2024.2 | 6.2.2 | openmpi 4.1.6 |
+| Fleur | 8.0 | — | openmpi 5.0.8 |
+| NWChem | 7.3.1 | 7.0.0 | openmpi 5.0.8 |
+| Quantum ESPRESSO | 7.5 | — | openmpi 5.0.8 |
+| Siesta | 5.4.2 | 7.0.0 | openmpi 5.0.8 |
+| Wannier90 | 3.1.0 | — | — |
+| Yambo | 5.3.0 | 6.2.2 | openmpi 4.1.6 |
+
+📦 **Updated AiiDA stack.** Upgraded to aiida-core 2.7 and Python 3.10.
+`aiida-nwchem` bumped to v3.
+
+📦 **Ubuntu 24.04 LTS.** The base OS has been upgraded from Ubuntu 20.04 to 24.04.
+Default VM memory has been increased from 1536 MB to 2048 MB.
+
+👌 **Cleaner PATH management.** Code binaries are now symlinked to `~/.local/bin` instead of adding full conda environment `bin/` directories to `PATH`.
+This prevents dependency binaries (Python, `pip`, `mpirun`, etc.) from leaking into the user's `PATH`.
+

+
+ 2. Install Virtual Box 7.2.6 or later (see <https://www.virtualbox.org>)
+ 3. Import virtual machine image into Virtualbox:
+    File => Import Appliance
+
+Login credentials: username: `max`, password: `moritz`.  
+The default configuration of `2` cores and `2048` MB RAM can be adjusted in the VM settings.
