Release v2.3.1

on GitHub

[v2.3.1] – 2026-06-05

No user-visible feature changes. This release adds reproducible builds —
locks the build toolchain so that the same source commit always produces
byte-identical binaries, giving users an independent way to verify a release
binary against the published source code.

See Verifying Releases in README.md and
Reproducible Builds in CONTRIBUTING.md
for the verification workflow and the full technical details.

Added

• setup-build-environment-example.cmd — a one-shot script that sets up a
  complete build environment on a fresh Windows installation (VM,
  Windows Sandbox,
  or similar), downloads the source tree from GitHub, installs Visual
  Studio Build Tools and CMake, and runs build.cmd to produce the
  distributable ZIP. Every step is visible and documented inside the script.

Changed

• Build toolchain pinned for reproducible builds. The exact MSVC compiler
  version (19.51.36246), toolset (14.51) and Windows SDK (10.0.26100.0)
  are locked in build.cmd and the CI workflow. The build uses the NMake
  Makefiles generator with the compiler environment activated per architecture
  via VsDevCmd.bat -vcvars_ver=14.51 — no VS generator flag is needed and
  cmake's VS instance detection is bypassed entirely.
  The MSVC compiler flags /Brepro, /experimental:deterministic and linker
  flag /BREPRO eliminate per-build noise from object files and the PE
  timestamp. Source-file paths in debug info are normalised via /pathmap.
  File timestamps in the ZIP are set to release-date= from pluginst.inf.
• sha256sums.sha256 added to every release ZIP. The file lists the SHA-256
  of every other file in the archive. The CI build log and build.cmd both
  print the SHA-256 of the produced ZIP itself, providing an independent
  reference for cross-build comparison.
• Line endings in ZIP text files normalised to CRLF. Markdown, INI and
  INF files in the release ZIP are now guaranteed to use Windows line endings
  regardless of the platform or git configuration the build was run under.
