Bit-Block V3.1

V3.1 is a security and build-fix release on top of V3. Updating is recommended for everyone, and strongly for anyone who uses -walletnotify.

Security

-walletnotify command injection fixed. The %w placeholder was filled in by a function that treated the wallet name as a regex replacement pattern. A wallet name containing a sequence such as $' could pull extra text into the command line, which is then run by a shell. The replacement is now literal. Only people who use -walletnotify and open wallets with untrusted names were exposed.

New in V3 (carried forward)

  • Seven individually switchable anti-spam relay and mining rules, modelled on BIP-110, in Options -> Spam filtering. They are local policy only and do not change consensus. All are on by default.
  • Optional DATUM Gateway preset (-datum or "Mine with DATUM" in Options) and a rate-limited templatehint ZMQ notification.
  • Advisory, dismissible upgrade reminder instead of any shutdown behaviour.
  • Chainstate compaction changes that stop LevelDB from rewriting large parts of the UTXO database every hour.
  • Version shown as "Bit-Block V3.1" on the splash screen, About dialog and --version.

Fixes

  • macOS: builds with the newest Homebrew Boost (1.91) and packages correctly into Bit-Block.zip. The dependency-copy step now handles @rpath libraries.
  • Linux: release build now includes the GUI (bitcoin-qt), and the archive name carries the version.
  • Windows: installer shows "V3.1" in its version fields.

Notes

  • macOS builds are not code-signed or notarized; macOS may ask you to approve the app on first launch.
  • The network user agent and the bitcoin: payment-link scheme are intentionally unchanged for compatibility.
  • Berkeley DB (legacy wallet) support is not included in the macOS build, because Homebrew no longer ships the required version. Descriptor wallets are unaffected.

V3.1 replaces the V3.0 built.
