0.6

This pre-release enables support for HTTP in CCF

Changed

• Quote format in getQuotes changed from string to vector of bytes (#566)
• Improved error reporting and logging (#572, #577, #620)
• Node certificates endorsed by the network (#581)
• The keygenerator.sh scripts replaces the keygenerator CLI utility to generate member and user identities.

Added

• HTTP endpoint support when built with -DHTTP=ON, see https://microsoft.github.io/CCF/users/client.html for details.
• [Only when building with -DHTTP=ON] The new scurl.sh script can be used to issue signed HTTP requests to CCF (e.g. for member votes). The script takes the same arguments as curl.
• listMethods RPC for luageneric app (#570)
• getReceipt/verifyReceipt RPCs (#567)
• Support for app-defined ACLs (#590)

Binaries for cchost and libluagenericenc.so are attached to this release. Note that libluagenericenc.so should be signed before being deployed by CCF (see https://microsoft.github.io/CCF/developers/build_app.html#standalone-signing).

0.5

This pre-release fixes minor issues and clarifies some of cchost command line options.

Removed

• The new_user function in constitution scripts (e.g. gov.lua) should be deleted as it is now directly implemented inside CCF (#550).
• cmake -DTARGET=all replaced with cmake -DTARGET=sgx;virtual. See https://microsoft.github.io/CCF/quickstart/build.html#build-switches for new values (#513).

Improvements

• The members and users certificates can now be registered by the consortium using clients that are not the memberclient CLI (e.g. using the tests/infra/jsonrpc.py module) (#550).
• Fix for Raft consensus to truncate the ledger whenever a rollback occurs and use commit_idx instead of last_idx in many places because of signatures (#503).
• Join protocol over HTTP fix (#550).
• Clearer error messages for when untrusted users/members issue transactions to CCF (#530).
• devcontainer.json now points to right Dockerfile (#543).
• cchost --raft-election-timeout CLI option default now set to 5000 ms (#559).
• Better descriptions for cchost command line options (e.g. --raft-election-timeout) (#559).

The cchost, libluagenericenc.so, keygenerator and memberclient are also attached to this release to start a CCF network with lua application.
Note that libluagenericenc.so should be signed before being deployed by CCF (see https://microsoft.github.io/CCF/developers/build_app.html#standalone-signing).

0.4

In this preview release, it is possible to run CCF with the PBFT consensus algorithm, albeit with significant limitations.

The evercrypt submodule has been removed, the code is instead imported, to make release tarballs easier to use.

0.3

This pre-release implements the genesis model described in the TR, with a distinct service opening phase. See https://microsoft.github.io/CCF/start_network.html for details.

Some discrepancies with the TR remain, and are being tracked under https://github.com/microsoft/CCF/milestone/2
