v1.0.19

Package renamed: slicot → ctrlsys

Changed

• PyPI package name changed from slicot to ctrlsys
• GitHub repo moved from jamestjsp/slicot to jamestjsp/ctrlsys
• pip install slicot now installs a shim that depends on ctrlsys and emits a deprecation warning
• All import slicot → import ctrlsys in user-facing code

Unchanged

• C internals (headers, guards, extension module name) unchanged
• All 600+ routines work identically

Migration

uv add ctrlsys

# Old
import slicot

# New
import ctrlsys

v1.0.18

Changed

• CI: consolidated 5 workflow files into 3 — eliminated redundant test runs on push
• CI: split publish pipeline into fast/slow phases — x86_64/macOS/Windows wheels on PyPI in ~12min, aarch64 follows ~90min later
• CI: CodeQL moved to weekly schedule only (was per-push)

Added

• Documentation badge and link in README and PyPI metadata

v1.0.17

• Fix Windows wheel build (scipy-openblas32 symbol prefix, pkgconfiglite checksums)
• Fix benchmark linker errors in cibuildwheel
• Fix ilaenv_ Fortran string length args (sporadic crash)
• Fix ab13hd bool-to-int for dtgsen LOGICAL parameter
• Remove unused variable warnings
• Restore PyPI README
• 11 completed C translations (+5.5k lines)
• Compiler warning cleanup (964 to 0)

v1.0.15

What's New

Added

• Complete 11 C translations from stubs: ab09iy, ab13dd, ab13hd, mb01uy, mb01vd, mb02pd, mb03bd, mb03xp, mb03yd, mb04pb, mb04rb, mb04tb (+5.5k lines)
• mb04pb test with expanded coverage
• LSP configs (.clangd, pyrightconfig.json)

Fixed

• Compiler warnings eliminated across 141 files (964 → 0)
• ab13hd workspace query in Python wrapper

Full Changelog: v1.0.14...v1.0.15

v1.0.14

Fixed

• sg03bx: E-standardization bugs — AS(2,2) typo and missing B rotation (upstream SLICOT-Reference#39)
• sg03bu/bv/bw: Lyapunov solver indexing and DSCAL pointer fixes
• mb04hd: restore (bool *) cast for GCC compatibility
• py_mb04: calloc→PyMem_Calloc for ASAN compatibility
• mb04rd: Linux OpenBLAS crash resolved — skip marker removed (#5)
• sb10kd: revert factor=1.0 to 1.1 for Linux/OpenBLAS compatibility

Added

• Expanded test coverage across 70 files (AB/AG/IB/MB/MC/MD/SB/SG/TB families)
• Residual verification tests for sg03bx
• User guide restructured around python-control workflows, added llms.txt

v1.0.13

Added

• sb02rd: condition estimation via SB02QD/SB02SD
• C11 vs Fortran77 benchmark infrastructure
• scripts/bump_version.py for atomic version updates with drift detection

Changed

• Migrated build system to uv
• Single source of truth for package version
• Python version requirement updated to 3.11+

Fixed

• Buffer overflows in 7 routines causing parallel test crashes
• Standalone meson setup build broken by absolute numpy include path
• CI gaps after build system migration to uv
• test_mb03rd: replaced scipy.linalg.solve with numpy
• Publish CI: scipy-openblas32 symbol prefix detection, OpenBLAS bundled LAPACK, sdist permissions

v1.0.12

Fixed

• ab13dd: L-infinity norm algorithm bugs causing 8.8% error for MIMO systems
  • Tolerance formula for imaginary-axis eigenvalue detection
  • Iteration loop count (off-by-one)
  • Algorithm structure: frequency collection, sorting, midpoint computation
  • MB03XD BALANC parameter ('B' not 'N')
  • Hamiltonian scaling (divide by gamma not gamma²)

See CHANGELOG.md for details.

v1.0.11

Fixed

• ab13dd: segfault for n=1 single-state systems (Fixes #9)
  • mb03xd requires T workspace even when JOB='E' (eigenvalues only)
  • Affects python-control's linfnorm() and system_norm() for first-order systems

v1.0.9

Changes

v1.0.8

Changes

• Add Python 3.14 wheel configuration
• Add scipy-openblas32 source build fallback for all platforms
