Fulcrum 2.1.3

on GitHub

What's New:

Fulcrum 2.1.3 is a minor maintenance release of the 2.x series. It contains one important bugfix as well as a refresh of the jemalloc library that is compiled with the release binary.

Detailed Summary of Changes (vs v2.1.2)

• Bugfix - Fix a bug with the internal Merkle::Cache class whereby it sometimes had an off-by-1 error. On BCH mainnet can be triggered with specifying cp_height on a certain boundary. Thanks to Jonathan Silverblood for catching this one.
• Updated the jemalloc library we compile into the release binary to version 5.4.0 latest.
• Some other minor internal nits and fixups.

Pre-compiled Binaries for Linux

I have provided two pre-built binaries for Linux:

• Fulcrum-2.1.3-x86_64-linux.tar.gz, which is compiled on an Ubuntu 18.04 system using Docker.
• Fulcrum-2.1.3-arm64-linux.tar.gz, which is compiled on an Ubuntu 20.04 system (for ARM64 bit) using Docker.

All of the above binaries contain jemalloc, libzmq, libminiupnpc, Qt6Core, Qt6Network (from Qt 6.10.0), OpenSSL 1.1.1 and libstdc++ statically linked. They still require libz2, and the right libc version as dynamic libs on your system (but those are usually present if you are on a recent system).

Pre-compiled Binaries for Windows

• Fulcrum-2.1.3-win64.zip - Pre-built, statically linked Windows version.
  • It should "just work" on any Windows 10 or above 64-bit system.
  • Includes is a statically-linked Fulcrum.exe, built with jemalloc, libzmq, libminiupnpc, Qt 6.10.10, OpenSSL 3.3.0, and gcc 15.2.0.
  • Additionally, FulcrumAdmin.exe is included which is the python script, but made into a onefile .exe using PyInstaller.
    • NOTE Windows virus scanners have been known to erroneously identify FulcrumAdmin.exe as containing a virus. This is because many heuristic scanners dislike the use of PyInstaller onefile .exe's. See: #203. Please ignore this -- we contain no viruses! Also please complain to your virus software vendor about this.

See the .asc file for signatures; I signed the sha256 hashes of all the release binaries. My gpg public key can be obtained here: https://github.com/Electron-Cash/keys-n-hashes/blob/master/pubkeys/calinkey.txt

Binary builds for macOS coming soon -- Until then you can always build from source!
