+## Performance Notes
+
+### BLAS Support
+
+This package supports BLAS libraries for improved linear algebra performance:
+
+- **With OpenBLAS**: Significant performance improvements for matrix operations
+- **Without BLAS**: Uses Eigen's built-in implementations (still efficient, but slower for large matrices)
+
+The build system will automatically detect and use OpenBLAS if available. You can verify BLAS support by checking the build output for messages like:
+
+```
+BLAS support enabled
+Found OpenBLAS at: /opt/homebrew/opt/openblas
+```
+
+### Troubleshooting
+
+**Build fails with "Could NOT find BLAS":**
+```bash
+# Install OpenBLAS first
+brew install openblas  # macOS
+sudo apt install libopenblas-dev  # Ubuntu
+
+# Then force BLAS detection
+SPARSEIR_USE_BLAS=1 uv sync
+```
+
+**OpenBLAS not detected automatically:**
+```bash
+# Set CMake prefix path manually
+export CMAKE_PREFIX_PATH="/usr/local/opt/openblas"  # or your OpenBLAS path
+export SPARSEIR_USE_BLAS=1
+uv sync
+```
+
+**Verify BLAS support in built package:**
+```python
+import pylibsparseir
+# Check build logs or library dependencies to confirm BLAS linking
+```

Subject: [PATCH 11/19] Add macOS support to Python C API CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add macOS to test matrix alongside Ubuntu
- Install OpenBLAS and Eigen via Homebrew on macOS
- Comment out CMAKE_PREFIX_PATH and PKG_CONFIG_PATH for now
- Now tests run on 6 environments: Ubuntu + macOS × Python 3.10/3.11/3.12

Subject: [PATCH 13/19] Enable parallel builds using matrix strategy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Split builds by Python version (3.10, 3.11, 3.12, 3.13) for parallel execution
- Each OS + Python version combination runs as independent job (12 total jobs)
- Dynamic CIBW_BUILD configuration using matrix.python_version
- Unique artifact names for each build combination
- Significant build time reduction through parallelization

Build matrix:
- Linux: 4 parallel jobs (ubuntu-latest × cp310-313)
- macOS Intel: 4 parallel jobs (macos-13 × cp310-313)
- macOS Apple Silicon: 4 parallel jobs (macos-latest × cp310-313)

Subject: [PATCH 14/19] Fix artifact naming and simplify matrix configuration

- Replace invalid '*' character in artifact names with clean py_tag values
- Use py_tag field consistently for both CIBW_BUILD and artifact naming
- Remove redundant python_version field from matrix
- Simplify matrix entries by using py_tag for cleaner configuration
- Fix GitHub Actions compliance issues with artifact naming constraints

Artifact names now follow pattern: wheels-{os}-{arch}-{py_tag}
CIBW_BUILD now uses: {py_tag}-* format for consistent wheel building

Subject: [PATCH 15/19] Fix Linux build: Use micromamba to install OpenBLAS in
 manylinux containers

- Replace traditional package managers (yum/dnf/apt-get) with micromamba
- Install OpenBLAS from conda-forge channel to /opt/openblas
- Update CMAKE_PREFIX_PATH and PKG_CONFIG_PATH to include new installation path
- Fixes 'command not found' error for package managers in manylinux_2_28_x86_64 container
