v4.14.5.1

Argentum 4.14.5.1

A modernization release: Argentum now builds and runs on current toolchains and
ships multi-platform binaries (Linux and Windows), including the Qt5 wallet GUI.
No consensus rules were changed.

What's new in 4.14.5.1

Build & toolchain modernization

The tree previously required a ~2017 stack (OpenSSL 1.0.x, Boost ~1.58, GCC 5, C++11)
and would not compile on a modern system. It now builds cleanly on GCC 13 / Clang,
OpenSSL 3.0, Boost 1.83+, BerkeleyDB 5.x, C++14. Notable fixes:

• Rewrote CBigNum (bignum.h) to wrap a heap BIGNUM* — OpenSSL 1.1+ made BIGNUM
  opaque and removed BN_init(). Arithmetic is byte-for-byte unchanged (it feeds the
  multi-algo geometric-mean chainwork calc).
• Boost 1.74+: const-qualified multi_index comparators; boost::placeholders for
  _1/_2; boost::signals2 disconnect via saved connection objects; modern
  boost::filesystem (is_absolute, copy_options, path().filename()).
• Added missing <list>/<functional>/<array>/<deque>/<stdexcept> includes (libc++/mingw).
• Replaced C++17-removed std::random_shuffle; version-guarded the pre-1.1 OpenSSL
  threading callbacks; UPnP UPNP_GetValidIGD for miniupnpc API ≥ 18.

Qt5 wallet GUI

• Ported the GUI from Qt4 to Qt5 (argentum-qt).
• Added a CMake build for the GUI so it builds on MSYS2/Windows.

Multi-platform releases (CI)

• A GitHub Actions pipeline builds and publishes Linux and Windows argentumd,
  argentum-cli, argentum-tx, and the Qt5 GUI (self-contained, DLLs/plugins
  bundled). macOS is best-effort (subject to GitHub Intel-runner availability).

Networking

• Baked in three new fixed seed nodes: 51.83.11.113, 85.15.179.171, 91.206.16.214.

Localization

• Czech (cs) fully re-localized from Bitcoin to Argentum, with correct Latin
  neuter (-um) declension and apposition.

Security / hardening (non-consensus)

• Added LOCK(cs_main) to the chaindynamics and getblockspacing RPCs (they walked
  the block index unlocked — a data race / potential use-after-free vs a reorg).
• Removed leftover developer debug-logging.

Tests

• Restored the regtest genesis block (its creation was commented out upstream) and
  refreshed stale test vectors — 54 / 56 unit suites pass.

Credits

• Modernized build and multi-platform packaging by hclivess.

Known issues

• macOS binaries are best-effort (GitHub Intel-runner availability).
• Two unit suites (auxpow_tests, miner_tests) require a consensus change and are
  intentionally left failing (no hardfork).
