v2.3.4

What's Changed

• Update necpp_src to v2.3.4 — see upstream changelog
  • Breaking: get_impedance_real/imag now accept feed_index parameter (imp.back() → imp[0])
  • New: nec_impedance_real_indexed/imag_indexed C API for specific feeds
  • Doxygen documentation for multi-feed access patterns
  • v2.3.3: Fix GX solve and three-plane symmetry reflection
• Update PyNEC SWIG interface to match new impedance API

v2.3.2

What's Changed

• Update necpp_src to v2.3.2 — see upstream changelog
  • v2.3.2: NE/NH near-field blank count defaults to 1 (NEC-2 Part 3 compliance)
  • v2.3.2: Memory safety fixes — prevent duplicate close and invalid pattern reads
  • v2.3.2: Fix uninitialized read for average-only radiation-pattern rows
  • v2.3.1: Upgrade segment/patch counts to int64_t for large simulations
  • v2.3.0: Fix flat-spiral helix (GH HL=0) degenerating to straight wire

Full Changelog: v2.2.6...v2.3.2

v2.2.6

What's Changed

• Add Python 3.14 wheel builds (cp314 on Linux + macOS ARM)
• Drop Python 3.10 wheels — minimum supported version is now 3.11
• Bump requires-python from >=3.9 to >=3.11
• Add Programming Language :: Python :: 3.14 classifier

Full Changelog: v2.2.5...v2.2.6

v2.2.5

What's Changed

• Fix: Include Eigen headers in source distribution. graft necpp_src/src/eigen added to MANIFEST.in so pip install from sdist no longer fails with fatal error: Eigen/Dense: No such file or directory.
• Use recursive-include for necpp_src/src to ensure all headers and sources are packaged.

v2.2.4

• Auto-generate config.h in setup.py — no longer requires CMake before pip install

Full Changelog: v2.2.4...v2.2.5

v2.2.4

What's Changed

• Fix: pip install pynec and pip install necpp now work from source distribution without requiring CMake to be pre-run. config.h is auto-generated by setup.py at build time.
• Clean up docs: remove Python 2 references, outdated NEWS, stale install instructions
• Fix necpp README Python 3 syntax in example code

v2.2.3 — SC-card geometry fix + re-enabled patch test

Changes

• Bump necpp_src submodule to include:
  • fix(geometry): stop SC API cards from expanding into patch grids (#120) — resolves the hang in nec_rp_card on surface-patch geometries
  • fix(safe_array): use eigen_segment where callers mean a length (#121)
• Re-enable test_multiple_sc_cards::test_patch (no longer hangs)
• Update expected impedance/gain values to match corrected geometry

v2.2.2 — SC-card geometry fix + re-enabled patch test

Changes

• Bump necpp_src submodule to include:
  • fix(geometry): stop SC API cards from expanding into patch grids (#120) — resolves the hang in nec_rp_card on surface-patch geometries
  • fix(safe_array): use eigen_segment where callers mean a length (#121)
• Re-enable test_multiple_sc_cards::test_patch (no longer hangs)
• Update expected impedance/gain values to match corrected geometry

v2.2.1 — CMake-based necpp v2.2.0 engine, build fixes

v2.2.1

Changes

• Build fixes for the CMake-based necpp (v2.2.0) submodule:
  • Exclude nec_wasm.cpp from the Python extension source glob (Emscripten-only; broke native builds).
  • necpp/build.sh: fix submodule init (--init), document the necpp_src symlink required by setup.py.
  • PyNEC/setup.py: remove dead necpp_src/win32/ include dir (gone in CMake necpp; config.h is now CMake-generated in build/).
  • MANIFEST.in: point config.h include at src/config.h.in (generated, not committed).
  • Fix stale config.h comments in both setup.py files.
• Version bump to 2.2.1.
