Firominer v1.6.0

Firominer v1.6.0 restyles the desktop launcher in the Firo Core wallet's identity and rebuilds its overview around the miner's state.

Changes

• The launcher uses the Firo Core wallet's colors, typefaces (Saira SemiCondensed and Source Sans Pro), icons and status badges in the Light and Dark themes. System and high-contrast settings keep your platform's colors. The sidebar collapses to icons in narrow windows.
• The overview leads with the miner's state. Until setup is complete it says what is missing and the start button reads Set up mining; a saved solo setup asks only for its RPC password, which is never saved. Once ready, it names the pool or node and the payout address, and shows the last session's runtime, accepted shares and average hashrate, which are kept across restarts.
• While mining, a summary banner shows total hashrate, accepted shares, the last share and GPU power with efficiency, the hashrate chart shows its average, and each GPU has a card with its recent hashrate, temperature, fan, power and shares. Connecting, paused, reconnecting and stopping read consistently across the page, and readings that are no longer current are shown as unavailable rather than stale.
• The bundled fonts are licensed under the SIL Open Font License 1.1; their license texts are installed in share/firominer-gui/licenses. Mining, pool and node code is unchanged from v1.5.3.

Downloads and compatibility

Package variant	Requirements
cuda12.9-opencl	NVIDIA driver 575.57.08 or newer on Linux, or 576.57 or newer on Windows. Includes CUDA, OpenCL, and CPU diagnostics.
opencl	A vendor OpenCL driver for GPU mining. Includes OpenCL and CPU diagnostics. Use this variant on machines without a suitable NVIDIA driver.

Packages target compatible Ubuntu 22.04 or newer x86-64 systems and Windows 10/11 x64. The Linux GUI requires X11 or XWayland; native Wayland plugins are not included. CUDA runtime/compiler libraries and the Windows Visual C++ runtime are bundled. GPU drivers must be installed separately; a full CUDA Toolkit installation is unnecessary.

Extract the entire archive and keep its directory layout intact. Start ./bin/firominer-gui on Linux or bin\firominer-gui.exe on Windows. The GUI supports Mainnet Stratum pool mining and direct solo mining against your own Firo node. Other networks and advanced options remain available through ./bin/firominer or .\bin\firominer.exe. Windows packages also include the editable bin\mine_firo.bat launcher.

See the included docs/GUI.md for launcher use and docs/TESTING.md for command-line examples and verification. SHA256SUMS-v1.6.0.txt covers all four downloadable archives, and each archive includes an internal manifest. Keep the bundled sources/ directory and license notices with redistributed packages.

Validation

Publication is gated on core tests, AddressSanitizer/UndefinedBehaviorSanitizer, ThreadSanitizer, Linux and Windows CUDA/OpenCL package builds, GUI and solo-node tests, relocated-package smoke tests, and checksum verification. Linux package checks load both the bundled offscreen and X11 Qt plugins. GUI tests run on Qt 6.2 and 6.4 on Linux and Qt 6.8 on Windows. The workflow also verifies that the tag matches the source version and is on main.

The release workflow does not exercise physical GPU mining or accepted live-pool or solo blocks. Keep host solution verification enabled, and use --cl-no-subgroup if needed for driver compatibility.

Full changes since v1.5.3. Includes #39.

Firominer v1.5.3

Firominer v1.5.3 reduces repeated GPU work and fixes mining telemetry and hashrate reporting.

Changes

• CUDA and OpenCL continue from the next unscheduled nonce when a pool resends unchanged work, including a new share target, or mining resumes after a pause. This avoids searching the same range again. Progress is kept within the running miner, not across process restarts.
• Resumed GPU launches stay within bounded nonce ranges. CUDA searches remaining whole blocks with smaller launches; OpenCL waits for new work when its assigned range is spent.
• Default spacing between GPUs increases from 2^32 to 2^40 nonces, delaying overlap on unchanged ordinary jobs to over five hours at 60 MH/s per device. Ordinary jobs still have no hard segment limit and can eventually overlap; pool extranonce jobs use bounded ranges.
• Miner stop/start cycles within the same process preserve device telemetry rows and cumulative share counters, and stopped hashrates clear to zero. JSON and HTTP statistics and pool submissions use 64-bit hashrate conversions to avoid truncating large rates.

Firominer v1.5.2

Firominer v1.5.2 adds optional solo coinbase messages to the desktop launcher and includes the version number in release download filenames.

Changes

• Set an optional Coinbase message in the launcher's Solo settings. The message is saved for your next launch and embeds public text in blocks you mine. Enter it directly, without wrapping it in quotes, up to 80 UTF-8 bytes. Explorer display depends on the explorer.
• Test node and the check before starting solo mining require the node to acknowledge the exact message. Use Firo Core 0.14.18.1 or another version with coinbase-message support, or leave the field empty for nodes without it. Invalid Unicode, null characters, and messages over the byte limit are rejected locally. Unicode coinbase messages on Windows require Windows 10 version 1903 or newer.
• Identify downloads by version: all four archives and both Linux checksum sidecars now contain -v1.5.2 in their names. The combined checksum file is SHA256SUMS-v1.5.2.txt. Internal package paths are unchanged.

Full changes since v1.5.1. Includes #33 and #34.

Firominer v1.5.1

Firominer v1.5.1 adds Mainnet solo mining to the desktop launcher and improves its layout on smaller and scaled displays.

Changes

• Choose Pool or Solo in the desktop launcher. Solo connects directly to your own synced Mainnet Firo node and uses a transparent Firo reward address. Pool and solo settings are saved separately; passwords stay in memory for the current session.
• Use the built-in node configuration guide and Test node action to check RPC access, network, sync status, reward address, and mining work before launching. Failed or cancelled checks do not start mining, and RPC credentials are kept out of logs.
• Monitor accepted blocks and node connection status in Solo mode. Setup and overview panels reflow for smaller windows, larger text, and display scaling.
• Expand GUI and controller tests for node failures, miner startup errors, responsive layouts, and Windows packaging.

Full changes since v1.5.0. Includes #31.

Firominer v1.5.0

Firominer v1.5.0 adds a Qt desktop launcher to the Linux and Windows packages and enables subgroup exchanges on supported AMD OpenCL GPUs.

Changes

• Configure mainnet pool mining in the desktop launcher, with saved pool and worker settings, live statistics and logs, and system tray support. Pool passwords stay in memory for the current session.
• Choose Light, Dark, or System appearance. The launcher starts the bundled miner and uses a password-protected local API connection to monitor and control it.
• Stop GUI-launched miners gracefully on Windows. The command-line miner and Windows batch launcher remain available.
• Use indexed subgroup shuffles for DAG-offset exchanges when the AMD OpenCL driver supports them. Subgroup exchanges are enabled by default on eligible AMD GPUs. Compilation failures fall back to subgroup broadcasts and then the portable kernel; --cl-no-subgroup explicitly selects the portable path. No measured hashrate improvement is claimed.
• Include the launcher, Qt libraries, matching GUI/library sources, and license notices in every release archive. No separate Qt or Python installation is needed.

Full changes since v1.4.0. Includes #28 and #29.

Firominer v1.4.0

Firominer v1.4.0 updates the supported dependency stack, improves GPU discovery across modern OpenCL runtimes, and reduces miner memory and verification overhead. It also fixes thermal pause handling, fatal Stratum response handling, and duplicate CUDA/OpenCL selection on NVIDIA systems.

Changes

• Updated managed packages to OpenSSL 3.5.8 LTS, Boost 1.92.0, JsonCpp 1.9.7, CLI11 2.6.2, and Khronos OpenCL components v2026.05.29. Release packages include resolved dependency versions and licenses.
• Replaced the old managed OpenCL loader so current Windows AMD and NVIDIA drivers can expose all installed platforms.
• Recognized AMD and NVIDIA GPUs by vendor ID on additional OpenCL runtimes, including Mesa Rusticl. PCI domains and functions are preserved when the runtime reports them.
• Prevented automatic mixed mode from starting separate CUDA and OpenCL miners for an NVIDIA GPU that cannot be matched safely. Use -G to select OpenCL explicitly in that case.
• Released temporary CUDA and OpenCL light caches after DAG generation, avoided duplicate simulation solution verification, and reduced CUDA digest-reduction operations. These changes do not establish an end-to-end hashrate gain.
• Kept thermal pauses unchanged when a temperature read fails, stopped buffered Stratum processing after fatal responses, and reaped completed asynchronous scripts on Linux.
• Added an editable bin/mine_firo.bat launcher to Windows packages and refreshed the miner artwork.
• Raised the minimum CMake version to 3.18 and removed obsolete OpenGL build prerequisites.
• Removed the redundant SHA256SUMS-windows.txt release asset. The combined SHA256SUMS.txt covers all four downloadable archives, and every package retains its internal manifest.

CUDA runtime/compiler libraries and the Windows Visual C++ runtime are bundled; GPU drivers are installed separately. A full CUDA Toolkit installation is unnecessary. Keep the extracted directory intact so the executable can find its companion libraries.

Maxwell, Pascal, and Volta NVIDIA GPUs remain supported with an appropriate R575 or R580 driver. R580 is the final driver branch supporting these architectures. CUDA packages require the driver versions above because FiroPoW kernels compile to PTX at runtime.

Launch ./bin/firominer on Linux or .\bin\firominer.exe in Windows PowerShell. Windows packages also include bin\mine_firo.bat, which can be edited with pool and wallet details. Select -U for CUDA or -G for OpenCL. See the included docs/TESTING.md for checksum verification, device selection, and pool or solo mining examples.

Validation

Publication is gated on core tests, AddressSanitizer/UndefinedBehaviorSanitizer, ThreadSanitizer, Linux CUDA/OpenCL package builds, Windows CUDA/OpenCL package builds, package smoke tests, and checksum verification. The release workflow also verifies that the tag matches the source version and is on main.

Development validation covered Windows discovery of an RTX 4090 and AMD gfx1036, CUDA/OpenCL PCI identity normalization, managed and system OpenCL builds, and CPU-verified CUDA kernel results. The exact release binaries have not been exercised on physical GPUs or a live pool, and no end-to-end hashrate improvement is claimed. Keep host solution verification enabled.

Full changes since v1.3.0. Includes #18, #19, #20, #21, #22, #23, #24, and #25.

Firominer v1.3.0

Firominer v1.3.0 updates CUDA packages to CUDA 12.9 Update 2, enables OpenCL helper inlining by default, and removes the desktop launcher. Start the miner from a terminal; Python and Tk are no longer required to run it.

Changes

• OpenCL automatically retries the legacy mix kernel if compilation fails. Use --cl-no-inline for driver compatibility. The existing --cl-experimental-inline flag remains accepted.
• Added experimental --cl-subgroup DAG-offset broadcasts for compatible AMD GPUs. This option remains off by default, with portable fallbacks for unsupported devices, incompatible subgroup layouts, and compilation failures.
• Linux packages now use C/C++ link-time optimization while retaining a generic x86-64 CPU baseline.
• Fixed Windows release archive downloads and OpenCL source embedding for MSVC builds.
• Added SHA256SUMS.txt covering all four Linux and Windows download archives. The existing Linux .sha256 files, Windows checksum manifest, and checksums inside each package remain available.

Known dependency limitation

These packages still bundle OpenSSL 1.1.1g. The OpenSSL 1.1.1 series is out of upstream support and no longer receives public security fixes. Updating this dependency remains outstanding.

Validation

Publication is gated on core tests, AddressSanitizer/UndefinedBehaviorSanitizer, ThreadSanitizer, Linux and Windows package builds, package smoke tests, and checksum verification. Offline OpenCL checks cover four kernel variants across three periods and three workgroup sizes.

Physical GPU execution, accepted pool shares, and hashrate improvements have not been validated for this release. Keep host solution verification enabled. Automatic kernel fallback handles compilation failures; it cannot detect a driver that compiles an incorrect kernel.

Full changes since v1.2.0. Includes #15, #16, and #17.

Firominer v1.2.0

Changelog

Added

• Desktop launcher for solo and pool mining, with live logs and OpenCL device detection.
• --firopow-network support for mainnet, testnet, devnet, and regtest epoch schedules.
• Optional UTF-8 solo coinbase messages, with a companion Firo daemon patch.
• Opt-in --cl-experimental-inline OpenCL kernel variant.
• Checksum-verified Linux and Windows CUDA/OpenCL release packages.

Changed

• Improved CUDA and OpenCL work scheduling, nonce-range handling, low-difficulty behavior, and device recovery.
• Hardened Stratum and Getwork parsing, timeouts, reconnection, and asynchronous shutdown. Solo Getwork now requires a reward address.
• Protected API status access when a password is configured and redacted pool credentials from the unauthenticated HTTP view.
• Made --cl-global-work control the OpenCL work multiplier instead of being ignored.
• Expanded FiroPoW, miner-state, protocol, API, GUI, sanitizer, and packaging tests.

Fixed

• Fixed mismatched FiroPoW epochs and invalid solo Getwork jobs.
• Fixed overlapping OpenCL scratch storage and generated-kernel paths containing spaces.
• Fixed Getwork socket lifetime, pool shutdown ordering, malformed coinbase UTF-8, and out-of-bounds unit formatting.
• Fixed current Linux and Windows toolchain compatibility and Windows CUDA runtime packaging.

Compatibility and validation

• Non-mainnet miners must select the matching --firopow-network; mainnet remains the default.
• Solo Getwork requires --reward-address.
• Coinbase messages are limited to 80 valid UTF-8 bytes, require the included patch for Firo 0.14.15.3 source, and are not supported by pools.
• When --api-password is set, HTTP monitoring returns 401. Authenticate through the plain TCP JSON-RPC API with api_authorize.
• --cl-experimental-inline remains off by default.
• Packages target compatible Ubuntu 22.04 or newer x86-64 systems and Windows 10/11 x64. They are unsigned and require host GPU drivers; CUDA packages require an NVIDIA driver.
• CI passed core tests, ASan/UBSan, ThreadSanitizer, package smoke tests, and checksum verification. No physical GPU execution, hashrate, or accepted-share testing was performed. The companion daemon patch's full rebuilt-daemon regression was not run in this workspace.
