Release 4.1.0-rc2

This CDT release is required when compiling System Contracts for use with the Savanna Consensus algorithm used with release Spring 1.0. This release includes full support for BLS cryptography and managing BLS signatures.

In addition there are a number of usability features.

  • Export memory from wasm file for use with Vert
  • Supports MacOS with native linking
  • BLS cryptography as a host function

Note: Running full integration tests requires linking to Spring libraries. If no integration tests are needed, CDT may be build and installed independent from Spring.
Note: Changes from RC1 adding a test as described in PR #299
