MeowMiner v1.6.53 - LuckyPool pre-hash fix

MeowMiner v1.6.53 - BTX v0.33 + Pearl multi-coin

MeowMiner v1.6.53 combines the native BTX and Pearl NVIDIA miners behind one
--coin btx|pearl launcher on Windows, Linux, and HiveOS.

What changed

• BTX candidates now receive a final consensus pre-hash check against the exact
  submitted header after meeting the pool share target and before emission.
  This prevents LuckyPool code 23 (BTX pre-hash gate failed) rejects even if
  the earlier CUDA scan-stage CPU recheck is explicitly disabled.
• CUDA scan CPU recheck now defaults on as an earlier safety filter.
• LuckyPool sessions now say LuckyPool / luckypool job in user-facing logs;
  the shared native protocol identifier remains internal.
• BTX now defaults to LuckyPool US-East at
  btx-us-east.lproute.com:8660 on every packaged platform.
• Retained BTX v0.33 parentMtp validation and the Pearl v1.6.43
  architecture-specific engines for sm_86, sm_89, sm_90, and sm_120.
• BTX uses the pool-validated 0.33.0-opt37-luckypool-prehashfix CUDA solver. BTX has no dev fee;
  Pearl retains its 2% dev fee.

Validation

• Released Windows solver control: 2 accepted / 12 code-23 rejects in 219s.
• Patched Windows solver: 8 accepted / 0 rejects across three independent
  LuckyPool canaries totaling about 268s, including a clean parent change.
• Final extracted v1.6.53 Windows archive: 3 accepted / 0 rejected in a
  140-second LuckyPool canary; it crossed a clean parent change and discarded
  the stale old-job result.
• The decisive canary ran with scan-stage CPU recheck disabled, isolating the
  final exact-header guard as the effective fix.
• Logs showed LuckyPool and luckypool job; no ninjaraider label appeared.
• Targeted wrapper tests passed: 51 passed, 2 skipped.
• RTX 5070 model fixture selected batch 128 and four CUDA pool slots.
• Pearl accepted shares: HeroMiners, RTX 5070 Ti, zero invalid shares during canary.
• Windows PowerShell launcher parse/help smoke test passed.
• Linux and HiveOS shell syntax checks passed.
• Staged mining-binary SHA256 values match the validated source packages.
• Archive layout checks passed for all three targets.

MeowMiner v1.6.52 — LuckyPool + RTX 5070 Windows hotfix

MeowMiner v1.6.52 - BTX v0.33 + Pearl multi-coin

MeowMiner v1.6.52 combines the native BTX and Pearl NVIDIA miners behind one
--coin btx|pearl launcher on Windows, Linux, and HiveOS.

What changed

• LuckyPool regional endpoints now use their native wallet.worker / password
  login directly instead of probing unsupported Stratum methods first.
• Added a 30-second first-job watchdog so an authorized but idle LuckyPool
  session reconnects instead of hanging forever.
• Added a Windows RTX 5070 (12 GB) compatibility profile: threads 8,
  prepare-workers 8, batch 128, and four CUDA pool slots. v1.6.51 incorrectly
  left this non-Ti card on the generic batch-512 / eight-slot profile.
• Retained BTX v0.33 parentMtp validation and the Pearl v1.6.43
  architecture-specific engines for sm_86, sm_89, sm_90, and sm_120.
• BTX uses the pool-validated 0.33.0-opt36-luckypool-winfix CUDA solver. BTX has no dev fee;
  Pearl retains its 2% dev fee.

Validation

• Patched Windows BTX package: LuckyPool US-East accepted share, 1 accepted / 0 rejected.
• LuckyPool direct-login, initial-job watchdog, and host-detection regression tests passed.
• RTX 5070 model fixture selected batch 128 and four CUDA pool slots.
• Pearl accepted shares: HeroMiners, RTX 5070 Ti, zero invalid shares during canary.
• Windows PowerShell launcher parse/help smoke test passed.
• Linux and HiveOS shell syntax checks passed.
• Staged mining-binary SHA256 values match the validated source packages.
• Archive layout checks passed for all three targets.

MeowMiner v1.6.51 - BTX v0.33 + Pearl multi-coin

MeowMiner v1.6.51 combines the native BTX and Pearl NVIDIA miners behind one
--coin btx|pearl launcher on Windows, Linux, and HiveOS.

What changed

• Updated BTX pool work for v0.33 template context, including parentMtp seed
  handling and fail-closed validation when a post-upgrade job omits it.
• Added a common multi-coin launcher for BTX and Pearl.
• Added --devices GPU selection so separate instances can mine different
  coins concurrently on disjoint GPUs.
• Retained the Pearl v1.6.43 architecture-specific engines for sm_86,
  sm_89, sm_90, and sm_120.
• BTX uses the pool-validated 0.33.0-opt35-v033ctx CUDA solver. BTX has no dev fee;

MeowMiner Cereblix v1.6.50

MeowMiner Cereblix v1.6.50 is a static-difficulty hotfix for Cereblix pool miners.

What changed:

• Fixed -p / --pass handling in MeowMiner Cereblix. Previous builds accepted the option but always sent pass: x to Stratum.
• Fixed the Linux/HiveOS launcher so it forwards -p / --pass to the real miner instead of discarding it.
• -p diff=N now reaches the Cereblix Stratum server, which pins fixed share difficulty and disables vardiff for that connection.
• Windows start.bat now accepts a fourth argument for pass/difficulty, for example start.bat crb1youraddress worker1 28 diff=1000000.
• Linux and HiveOS package docs now call out static difficulty usage. Linux already supports PASS=diff=N; HiveOS uses the flight sheet pass field.
• Kept the 2.00% MeowMiner dev fee wallet/endpoint unchanged: crb1c41078c7d958b88042c22f0c3c4cbedc9e8d9dba at us.cereblix.com:3333.

Static difficulty guidance:

• The Cereblix Stratum code targets about one share every 12 seconds under vardiff.
• For an 80 kH/s mini rig, start around diff=1000000.
• If pool-side hashrate still looks jumpy, lower the value; if share traffic is too high, raise it.

MeowMiner Cereblix v1.6.48

MeowMiner Cereblix v1.6.48 is a Windows compatibility hotfix for users seeing immediate restarts with exit code 3221225501 / 0xC000001D.

What changed:

• Rebuilt the Windows binary with a portable x86-64-v2 + AES-NI baseline instead of -march=native.
• Kept AVX2, VAES, and AVX512 optimized paths runtime-dispatched only when the CPU supports them.
• Updated the packaged Windows build.ps1 to use the portable baseline so future Windows builds do not accidentally bake in the builder CPU's instruction set.
• Rebuilt Windows, Linux, and HiveOS assets as v1.6.48 so all packages report the same version.

Smoke checks:

• Windows: --cpu-threads=2 starts BENCH: 2 workers.
• Windows main disassembly check showed no ymm/zmm/AES instructions baked into startup/main.
• Linux v3 under WSL: --cpu-threads=2 starts BENCH: 2 workers.
• HiveOS archive preserves executable bits for h-run.sh, wrapper, and miner binaries.

MeowMiner Cereblix v1.6.47

MeowMiner Cereblix v1.6.47 adds manual CPU thread-count overrides for Cereblix autotune across Windows, Linux, and HiveOS.

Changes:

• Added Cereblix thread override aliases: -t N, -threads N, --threads=N, --cpu-threads=N, threads=N, and cpu_threads=N.
• Added env/config override support: CEREBLIX_THREADS, NM_THREADS, CUSTOM_THREADS, and CUSTOM_CPU_THREADS.
• Explicit thread overrides automatically skip Cereblix thread autotune with -noauto.
• Linux start.sh, Windows start.bat, and HiveOS h-config.sh now expose/validate positive integer thread overrides.
• Rebuilt Windows, Linux, and HiveOS release assets from MM_VERSION=1.6.47 source.

Smoke checks:

• Windows: --cpu-threads=2 starts BENCH: 2 workers.
• Linux v3 under WSL: --cpu-threads=2 starts BENCH: 2 workers.
• HiveOS archive preserves executable bits for h-run.sh, wrapper, and miner binaries.

MeowMiner Pearl v1.6.43 Full OS Parity

MeowMiner Pearl v1.6.43

Full OS parity release for Pearl. Windows, Linux, and HiveOS now all ship the architecture-specific engines and auto-select the correct kernel per GPU.

What changed

• Windows package now includes MeowMiner-pearl.sm86.exe and routes RTX 30-series / sm_86 GPUs to it.
• Linux package uses the same sm86 fixed-grid/no-forced-L2 default as HiveOS.
• HiveOS full package replaces the sm86-only detour; one HiveOS package now supports RTX 30, 40, and 50-series Pearl mining.
• All three launchers select by compute capability per GPU:
  • 8.6 -> MeowMiner-pearl.sm86 / MeowMiner-pearl.sm86.exe
  • 8.9 -> MeowMiner-pearl / MeowMiner-pearl.exe
  • 9.0 / 12.0 -> MeowMiner-pearl.legacy / MeowMiner-pearl.legacy.exe
• RTX 30-series sm86 defaults to fixed-grid from SM count, PEARL_SM86_AUTO_L2BLOCK=0, and no forced L2 block unless explicitly set with PEARL_SM86_* overrides.
• Keeps the Pearl pool client fee behavior at 2%.
• Keeps HeroMiners examples and default starter pool on us2.pearl.herominers.com:1200.
• Does not change clocks, power limits, fan settings, or OS tuning.
