+## [2.26.3] - 2026-03-13
+
+### Fixed
+- **SatDump AVX2 crash** — SatDump now compiles with `-march=x86-64` on x86_64 platforms (Docker and `setup.sh`), preventing "Illegal instruction" crashes on CPUs without AVX2. SIMD plugins still use runtime detection for acceleration on capable hardware. (#185)
+
+---
+
+## [2.26.2] - 2026-03-13
+
+### Fixed
+- **Docker startup crash** — `.dockerignore` excluded the entire `data/` directory, which is now a Python package (`data.oui`, `data.patterns`, `data.satellites`). Caused `ModuleNotFoundError: No module named 'data.oui'` on container startup. Fixed by only excluding non-code files from `data/`.

Smittix	8ef9dca6ee	fix(build): compile SatDump with baseline x86-64 to avoid AVX2 crashes (#185 ) On x86_64, explicitly pass -march=x86-64 so the compiler emits only baseline instructions. SatDump's SIMD plugins still compile with their own per-target flags and do runtime CPU detection, so AVX2 acceleration remains available on capable hardware. ARM builds are unaffected.

Smittix	4610804de6	v2.26.2: fix Docker startup crash — data/ package excluded by .dockerignore The data/ directory became a Python package (oui.py, patterns.py, satellites.py) in v2.26.0, but .dockerignore still blanket-excluded it as runtime data. This caused ModuleNotFoundError: No module named 'data.oui' on container startup. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-13 16:35:22 +00:00
