Garlicoin Core 0.18.5 - GRLC.eu Maintenance Release

Garlicoin Core 0.18.5 release notes

Garlicoin Core 0.18.5 is the stable maintenance release for the maintained 0.18.x line.
It promotes the 0.18.5 release-candidate work after automated release validation and real Apple Silicon testing, and supersedes v0.18.4 as the current stable release.

Highlights

• Adds native macOS ARM64 release artifacts for Apple Silicon Macs.
• Keeps the existing native macOS x86_64 release for Intel Macs.
• Preserves the current Linux x86_64 and Windows x86_64 release targets.
• Keeps the existing Qt 5.15.19, OpenSSL 3.5.9 and Berkeley DB 4.8.30 maintenance baseline.
• Extends release validation with native ARM64 packaging, DMG checks, Allium regression vectors and Intel -> ARM64 -> Intel wallet compatibility checks.
• Includes targeted P2P and validation robustness fixes developed and validated during the 0.18.5 release-candidate cycle.
• Refreshes the Garlicoin Core / GRLC.eu maintenance presentation and points the About dialog at the maintained garlicoin/Garlicoin source repository.

P2P and validation maintenance

• Improves compact-block reconstruction state handling after a reconstruction attempt has completed.
• Ensures the getdata receive queue continues to make progress when it contains an inventory item that is not handled by the current path.
• Limits redundant getheaders responses while processing a single inv message.
• Fixes the lifetime of precomputed transaction data used by script checks during block connection.
• Makes orphan-transaction processing resumable instead of requiring all dependent work to complete in one pass.
• Preserves the peer ownership relationship for blocks that are already in flight.
• Adds per-peer rate limiting to addr processing to bound the amount of work performed for address announcements.
• Widens internal addrman entry identifiers to 64-bit values while keeping the existing serialized peers.dat format unchanged.

Build and release maintenance

• Fixes the native ARM64 release path so the ccache configuration directory exists before the parallel build starts.
• Makes build metadata recognize lightweight release tags so release binaries can be verified against the exact public tag.
• Finalizes the 0.18.5 user-visible maintenance text, including the Garlicoin Core 2011-2026 copyright range while preserving the historical Bitcoin Core 2009-2022 line.

Compatibility

This release does not intentionally change Garlicoin consensus, Allium proof of work, network identity, address formats, blockchain/datadir compatibility, RPC behavior, or the Berkeley DB wallet format.

It does include targeted maintenance changes to P2P state handling and resource management. Existing Garlicoin Core 0.18.x datadirs and wallets are intended to remain compatible.

macOS targets

This release provides two separate macOS builds:

• Intel x86_64, deployment target macOS 10.13;
• Apple Silicon ARM64, deployment target macOS 11.0.

The ARM64 build is a native thin ARM64 build. A Universal Binary is not part of 0.18.5.

Validation

The 0.18.5 release-candidate line passed the maintained release-validation pipeline across Linux x86_64, Windows x86_64, macOS Intel x86_64 and native macOS Apple Silicon ARM64, including packaging, DMG checks, focused tests, Allium regression vectors and Intel -> ARM64 -> Intel Berkeley DB wallet interchange.

A real Apple Silicon end-user test also confirmed that the ARM64 build launches and connects to peers successfully.

The final v0.18.5 tag is rebuilt and validated again by the exact-tag release pipeline before public release artifacts are published.

Signing and Gatekeeper

The current maintenance release pipeline does not add Apple Developer ID signing or notarization. macOS may therefore show the usual Gatekeeper warning for an unsigned application downloaded from the internet.

Release artifacts

The stable release includes:

• Linux x86_64 tarball;
• Windows x86_64 ZIP and installer;
• macOS Intel x86_64 TAR and DMG;
• macOS Apple Silicon ARM64 TAR and DMG;
• source archive;
• SHA256SUMS.

Verify downloaded artifacts against the published SHA256SUMS file before installation.

Garlicoin Core 0.18.5-rc2 - Release Candidate

Garlicoin Core 0.18.5 release candidate notes

Garlicoin Core 0.18.5-rc2 is a pre-release for the maintained 0.18.x line.
It supersedes 0.18.5-rc1 and combines the Apple Silicon release work with the maintenance and P2P robustness changes merged since rc1.

Highlights

• Adds native macOS ARM64 release artifacts for Apple Silicon Macs.
• Keeps the existing native macOS x86_64 release for Intel Macs.
• Preserves the current Linux x86_64 and Windows x86_64 release targets.
• Keeps the existing Qt 5.15.19, OpenSSL 3.5.9 and Berkeley DB 4.8.30 maintenance baseline.
• Extends release validation with native ARM64 packaging, DMG checks, Allium regression vectors and Intel -> ARM64 -> Intel wallet compatibility checks.
• Includes targeted P2P and validation maintenance merged after 0.18.5-rc1.

Changes since 0.18.5-rc1

• Improves compact-block reconstruction state handling after a reconstruction attempt has completed.
• Ensures the getdata receive queue continues to make progress when it contains an inventory item that is not handled by the current path.
• Limits redundant getheaders responses while processing a single inv message.
• Fixes the lifetime of precomputed transaction data used by script checks during block connection.
• Makes orphan-transaction processing resumable instead of requiring all dependent work to complete in one pass.
• Preserves the peer ownership relationship for blocks that are already in flight.
• Adds per-peer rate limiting to addr processing to bound the amount of work performed for address announcements.
• Widens internal addrman entry identifiers to 64-bit values while keeping the existing serialized peers.dat format unchanged.
• Refreshes maintained CI and release documentation used by the 0.18.x release process.

Compatibility

This release candidate does not intentionally change Garlicoin consensus, Allium proof of work, network identity, address formats, blockchain/datadir compatibility, RPC behavior, or the Berkeley DB wallet format.

It does include targeted maintenance changes to P2P state handling and resource management. Existing Garlicoin Core 0.18.x datadirs and wallets are intended to remain compatible.

macOS targets

The release candidate provides two separate macOS builds:

• Intel x86_64, deployment target macOS 10.13;
• Apple Silicon ARM64, deployment target macOS 11.0.

The ARM64 build is a native thin ARM64 build. A Universal Binary is not part of 0.18.5.

Release-candidate testing requested

The ARM64 build has passed the project release-validation pipeline on a native Apple Silicon GitHub Actions runner, but a final real-user check on an M1/M2/M3/M4 Mac is still requested before the stable 0.18.5 release.

For the ARM64 DMG, please verify:

• the DMG mounts normally;
• Garlicoin-Qt launches;
• a wallet can be created or opened;
• the application can be restarted and the wallet still opens;
• network synchronization starts normally;
• any Gatekeeper message is reported exactly as shown.

For all platforms, normal startup, synchronization, wallet use and peer connectivity are useful rc2 checks.

If possible, include the platform version and, for macOS, the Mac model/chip with the test result.

Signing and Gatekeeper

The current maintenance release pipeline does not add Apple Developer ID signing or notarization. macOS may therefore show the usual Gatekeeper warning for an unsigned application downloaded from the internet.

Release-candidate status

This is a GitHub pre-release and is not intended to replace v0.18.4 as the current stable release yet.
After successful rc2 validation and real-hardware testing, the project can publish the final v0.18.5 release.

Release artifacts

The pre-release is expected to include:

• Linux x86_64 tarball;
• Windows x86_64 ZIP and installer;
• macOS Intel x86_64 TAR and DMG;
• macOS Apple Silicon ARM64 TAR and DMG;
• source archive;
• SHA256SUMS.

Verify downloaded artifacts against the published SHA256SUMS file before installation.

Garlicoin Core 0.18.4 - GRLC.eu Maintenance Release

Garlicoin Core 0.18.4 is the corrected GRLC.eu maintenance release for the 0.18.x line.

This release supersedes v0.18.3 for normal downloads.

Highlights:

• restores the original Garlicoin wallet appearance;
• fixes Qt High-DPI initialization so Windows display scaling enlarges text and controls together without breaking the existing layout;
• keeps the Qt 5.15.19 and OpenSSL 3.5.9 maintenance baseline;
• preserves existing Garlicoin network, blockchain, datadir and wallet compatibility;
• includes validated x86_64 release packages for Windows, Linux and macOS.

Windows, Linux and macOS packages were built from commit 6efb07eb32e8dffd6b5a905eb3b35e322e3cfc1a and validated before publication.

SHA256 checksums are included in the SHA256SUMS asset.

Garlicoin Core 0.18.3 - GRLC.eu Maintenance Release

Garlicoin Core 0.18.3

Garlicoin Core 0.18.3 is a maintenance release focused on dependency modernization, build reliability, and current-platform compatibility while preserving the existing Garlicoin network, blockchain, wallet format, RPC interface, and Berkeley DB 4.8 wallet compatibility.

Highlights

• Refreshed the wallet GUI and Garlicoin / GRLC.eu presentation for the maintained 2026 edition.
• Fixed source-archive and Windows-installer packaging after documentation cleanup.
• Updated the Qt 5 line to Qt 5.15.19.
• Updated OpenSSL to 3.5.9.
• Preserved Berkeley DB 4.8.30 wallet compatibility.
• Added and validated current Linux, Windows x86_64, and native macOS x86_64 build paths.
• Improved Python 3.12+ compatibility in the P2P functional test framework.
• Removed obsolete BIP70 payment-protocol support while retaining ordinary garlicoin: URI handling.
• Added maintenance and release-validation CI coverage for current toolchains.

Compatibility

This release does not intentionally change consensus rules, proof of work, network parameters, address formats, the existing blockchain/datadir layout, the wallet format, or normal RPC behavior.

Existing wallet.dat files remain on Berkeley DB 4.8 compatibility.

Release platforms

The release workflow validates and publishes:

• Linux x86_64 archive
• Windows x86_64 archive
• Windows x86_64 installer (garlicoin-0.18.3-win64-setup.exe)
• macOS x86_64 archive
• macOS x86_64 DMG
• source archive
• SHA256 checksums

Dependency baseline

• Qt 5.15.19
• OpenSSL 3.5.9
• Berkeley DB 4.8.30

macOS

The supported release build is produced natively on an Intel macOS runner with Xcode 16 / macOS SDK 15.0 and a deployment target of macOS 10.13. Qt, OpenSSL, and Berkeley DB are linked from the repository depends build; non-system dynamic Qt/OpenSSL/BDB dependencies are not expected.

The deployment target is validated from the Mach-O load commands. Actual execution on every historical macOS point release is not implied by that metadata alone.

Windows

Windows release binaries are built for x86_64 with MinGW and packaged both as a ZIP archive and an NSIS installer. Qt and OpenSSL are linked statically in the validated release build.

Notes

This is a maintenance release in the Garlicoin Core 0.18.x line. The GUI refresh preserves the existing wallet operations. Migration to Qt 6 remains outside the scope of 0.18.3.

Garlicoin Core 0.18.2 - GRLC.eu Maintenance Release

Garlicoin Core 0.18.2

Garlicoin Core 0.18.2 is a maintenance release of the actively maintained GRLC.eu edition of Garlicoin Core.

This release continues the modernization and cleanup of the Garlicoin 0.18.x codebase while preserving compatibility with the existing Garlicoin network, blockchain, wallets, addresses and user datadirs.

Highlights

• improved compatibility with current Linux toolchains, including Ubuntu 22.04 and Ubuntu 24.04
• maintained deterministic builds for Linux, Windows and macOS
• Python 3.12+ compatible P2P functional test framework
• legacy BIP70 Payment Protocol implementation removed
• normal garlicoin: payment URIs remain supported
• additional build-system and dependency maintenance
• improved cross-platform CI and release validation
• Garlicoin branding and runtime message cleanup
• GRLC.eu maintained build identification

No consensus rules, proof-of-work parameters, address formats, wallet formats or network identity have been intentionally changed.

This release remains compatible with existing Garlicoin Core datadirs and wallets.
