v1.0.6

Notable changes in this release:

• Fix SV2 reserved weight handling by honoring Bitcoin Core’s minimum reserved weight and fixing a floor/cap regression so values below 2000 are treated correctly. (#79 and #82 by @Sjors)
• Use CoinbaseTemplate when available to avoid reconstructing coinbase fields from dummy transactions, with fallback behavior for older interfaces. (#59 by @Sjors)
• Change default ports to x8442 for the Stratum V2 endpoints. (#72 by @Sjors)
• Refresh key dependencies: depends now pins Boost 1.90.0 and native Cap’n Proto 1.3.0, and CMake/docs now require Boost 1.74.0 minimum. (#87 by @Sjors)
• Update bundled subtrees for libmultiprocess (v8 line) and secp256k1 (includes 0.7.1 prep and upstream fixes). (by @Sjors)
• Update docs to reflect minimum supported Bitcoin Core version v30.2. (#80 by @xyephy)

See README for instructions. TL;DR:

• install or compile Bitcoin Core v30.2
• bitcoin -m -ipcbind=unix
• bin/sv2-tp -debug=sv2 -loglevel=sv2:trace
• tail sv2-debug.log for runtime diagnostics

v1.0.5

Notable changes in this release:

• Fix the regression in v1.0.4 that accidentally disabled PruneBlockTemplateCache when -sv2interval ≤ 10s. The pruning timer now advances only when the best tip really changes. (#66 by @Sjors)
• Emit (trace) logs when pruning stale templates so operators can correlate template lifecycle events. (#64 by @Sjors)
• Restore PID management: -pid works again, sv2-tp now creates/removes its PID file, update sv2-tp.service systemd unit. (#68 by @Sjors)
• Switch the default -debuglogfile to sv2-debug.log to prevent writing into the same debug.log as Bitcoin Core. (#69 and follow-ups by @Sjors)
• Update documentation to reflect the move to the stratum-mining GitHub organization. (by @Sjors)

See README for instructions. TL;DR:

• install or compile Bitcoin Core v30
• bitcoin -m -ipcbind=unix
• bin/sv2-tp -debug=sv2 -loglevel=sv2:trace
• tail sv2-debug.log for runtime diagnostics

• improved logging during startup (#52 by @xyephy)
• reduce delay in sending NewTemplate (#56 by @Sjors)
• speed up ctrl + c (with future Bitcoin Core versions, #57 by @Sjors)
• show -logtimemicros in default help
• support multiple coinbase outputs (#55 by @xyephy)
• reduce getBlockHeader() IPC call (#58 by @Sjors)
• allow RequestTransactionData for stale templates for 10s (#61 by @Sjors)

See README for instructions. TL&DR:

• install or compile Bitcoin Core v30
• bitcoin -m -ipcbind=unix

v1.0.1

New in this release:

• macOS binaries are now code-signed and notarised, so you no longer have to manually code-sign them

See README for instructions. TL&DR:

• install or compile Bitcoin Core v30 or newer (not released yet)
  • download (release candidate) https://bitcoincore.org/bin/bitcoin-core-30.0/test.rc1/
• bitcoin -m -ipcbind=unix
• bin/sv2-tp -debug=sv2 -loglevel=sv2:trace

v1.0

The Template Provider is now a standalone program. It should behave the same as the last IPC release https://github.com/Sjors/bitcoin/releases/tag/sv2-tp-0.1.19-ipc, but no longer contains a bitcoin-node binary.

The bitcoin-mine command has been renamed to sv2-tp.

You need to self-sign the macOS binaries:

codesign -s - bin/*

See README for instructions. TL&DR:

• install or compile Bitcoin Core v30 or newer (not released yet)
  • download unofficial preview: https://github.com/Sjors/bitcoin/releases/tag/v30.0-alpha-1
• bitcoin -m -ipcbind=unix
• bin/sv2-tp -debug=sv2 -loglevel=sv2:trace
