Changelog

August 12, 2026 · View on GitHub

All notable changes to ForeFire are recorded here.

The format follows Keep a Changelog. Version numbers are the tags in this repository and the values reported by forefire -v; they are also what pip install forefire==<version> resolves.

Entries below v2.5.0 were reconstructed from the release notes and the commit history, so they summarise each release rather than list every change. The Full Changelog link on each version gives the complete commit range.

Unreleased

Merged since v2.5.0, not yet released.

Changed

  • Linux wheels are built against a NetCDF without DAP and HDF4, roughly halving the wheel. (#154)
  • Free-threaded (cp314t) wheels are no longer published, because the core is not yet thread-safe; CPython 3.14 is declared supported. (#155)

v2.5.0 — 2026-08-11

Added

  • Pip-installable wheels for Linux (x86_64, aarch64) and macOS (Apple Silicon and Intel), CPython 3.9 and newer. pip install forefire gives both the forefire command-line interpreter and the pyforefire module, with NetCDF bundled inside the wheel. Wheels are built without MPI and without -march=native. (#151)

Changed

  • The Dockerfile is a multi-stage build, and only libforefireL is built in the builder stage. (#147)
  • The install-forefire.sh build is driven by an option-based CMakeLists.txt (FOREFIRE_ENABLE_MPI, FOREFIRE_NATIVE_ARCH, FOREFIRE_BUILD_PYTHON, FOREFIRE_STATIC_CORE, FOREFIRE_BUILD_TOOLS, FOREFIRE_CHECK_LFS).

Fixed

  • A double free in FireFront cleanup. (#145)
  • CMakeLists.txt was matched by .gitignore, so it was missing from the source distribution. (#152)
  • Bugs in tests/run.bash, including a runANN typo and an unreachable ./clean.bash. (#146)

v2.0 — 2025-06-05

The V2 release: the HTTP interface, and alignment with Meso-NH V4.7.2.

Added

  • The built-in HTTP command server and web UI (listenHTTP[], or forefire -l), serving a map view of the simulation.
  • The Read the Docs documentation site, built with Sphinx, Breathe and Doxygen.
  • install-forefire.sh, with -y to add forefire to PATH and set FOREFIREHOME.
  • A working Dockerfile, and GitHub Actions for Linux and macOS.
  • The RothermelAndrews2018 propagation model. (#34)

Changed

  • CMake replaces SCons throughout; references to SCons were removed.

Fixed

  • The -lnetcdf_c++4 link failure. (#26)
  • A division by zero in setArrivalTime/getArrivalTime. (#36)

v1.2 — 2024-01-16

v1.1.10 — 2022-10-25

Changed

v1.1.0 — 2022-09-28
