This release introduces the Staking UI with a duration selector, switches macOS distribution to fully static linking, upgrades core dependencies (Boost, OpenSSL, Qt) with ARM64 support, fixes icon theming on macOS and Windows, and ships extensive build system improvements.

Major Changes

Staking UI

  • “Start staking” panel added to the Overview page with duration selector (1h / 6h / 24h / 7d / 30d)
  • Live countdown timer showing remaining staking time with progress bar
  • “Stop staking” button with confirmation dialog
  • Passphrase prompt via existing wallet unlock dialog (new UnlockStaking mode)
  • Auto-relock via QTimer when staking duration expires
  • Staking panel hidden for unencrypted wallets (staking is always-on without encryption)
  • Panel appears automatically after encrypting the wallet (no restart needed)
  • Non-persistent: staking state resets on app restart (wallet starts locked)
  • Full translations for all 34 supported languages

Icon Theme Fix

  • All icons now render in theme-adaptive color on both light and dark themes
  • Enabled icon colorization on macOS and Windows (previously only Linux)
  • Icons use WindowText palette color, matching the rest of the UI text

Static Linking for macOS Distribution

  • Switched macOS release builds from Homebrew dynamic libraries to a fully static depends/ system
  • Release binaries no longer require Homebrew packages on user machines
  • Eliminates “dyld: Library not loaded” crashes for boost@1.85 and other libraries

Dependency Upgrades (depends/ system)

  • Boost: 1.64.0 → 1.88.0 (ARM64 macOS support, C++17)
  • OpenSSL: 1.0.1k → 3.4.1 (ARM64 macOS support, security fixes, modern TLS)
  • Qt: 5.9.6 → 5.15.16 (ARM64 macOS support, last Qt5 LTS)
  • libevent: 2.1.8 → 2.1.12
  • ZeroMQ: 4.3.1 → 4.3.5
  • protobuf: 2.6.1 → 3.21.12
  • qrencode: 3.4.4 → 4.1.1
  • zlib: 1.2.11 → 1.3.1
  • miniupnpc: 2.0.20180203 → 2.2.8
  • macOS minimum version: 10.10 → 11.0 (required for Apple Silicon)

Build System Enhancements

  • macOS CI workflow rewritten to use the depends/ static build (matches Windows CI)
  • build_macos.sh rewritten to use the identical depends/ flow as CI
  • Only build tools (automake, libtool, pkg-config) needed from Homebrew
  • otool -L verification step in CI to catch dynamic linking regressions
  • Fixed dead Boost download URL (dl.bintray.com → archives.boost.io)
  • Replaced deprecated SSL_library_init() with OPENSSL_init_ssl() for OpenSSL 3.x
  • Added -isysroot to build_darwin_CC/CXX for macOS 15/26 SDKs
  • Updated Qt 5.15 patches for the new source layout; disabled OpenGL and Vulkan for macOS (AGL removed in macOS 26 SDK)
  • Updated miniupnpc build/stage paths for 2.2.8 layout and UPNP_GetValidIGD call for miniupnpc API 18
  • Linux x64/ARM64 CI runners bumped from ubuntu-22.04 to ubuntu-24.04
  • Linux CI and build_linux.sh now statically link Boost so binaries run on any Ubuntu regardless of installed libboost version
  • All build workflows now trigger on pull_request against main for compile-only verification
  • Bumped actions/checkout from v4 to v5 across all workflows
  • build_linux.sh pre-checks system libs via pkg-config and points to --install-deps if missing
  • Added build_windows.sh for cross-compile from Ubuntu via MinGW-w64, matching the Windows CI step-for-step
  • Windows cross-compile: WINDRES set per host for OpenSSL 3.4.1 MinGW; Qt patched with -no-feature-schannel and OpenSSL 3.x link-test for MinGW
  • Qt: replaced -dbus-runtime with -no-dbus globally (D-Bus unused by taler-qt)
  • Added retry-once to the depends/ build step to work around an intermittent Qt 5.15 moc/plugin parallel-build race
  • macOS: link CoreVideo, IOSurface, Carbon, QuartzCore and Metal frameworks so Qt’s static libqcocoa.a resolves on macOS 26 SDK
  • Windows: link wtsapi32, userenv, netapi32 and Qt5WindowsUIAutomationSupport static library so libqwindows.a links correctly
  • Fixed plugin link-test ordering so platform library additions run before the QMinimalIntegrationPlugin test
  • Dropped obsolete __MINGW32__ Boost 1.85+ copy_option branch in wallet db code
  • build_macos.sh gained clean and clean-all subcommands and auto-runs autogen.sh when configure.ac / M4 / Makefile.am files are newer than configure (build_windows.sh gains the same behavior)
  • Rewrote README.md as a modern open-source project landing page with CI/metadata badges, SEO description, Docker quick-start, and cross-platform self-compile pointers
