ccf-0.14.2

Changed

• The start_test_network.sh script has been replaced by sandbox.sh. Users wishing to override the default network config (a single node on '127.0.0.1:8000') must now explictly specify if they should be started locally (eg. -n 'local://127.4.4.5:7000') or on remote machine via password-less ssh (eg. -n 'ssh://10.0.0.1:6000').
• node/quote endpoint now returns a single JSON object containing the node's quote (#1761).
• Calling foreach on a TxView now iterates over the entries which previously existed, ignoring any modifications made by the functor while iterating.

ccf-0.14.1

Added

• /node/memory endpoint exposing the maximum configured heap size, peak and current used sizes.

Changed

• Public tables in the KV must now indicate this in their name (with a public: prefix), and internal tables have been renamed. Any governance or auditing scripts which operate over internal tables must use the new names (eg - ccf.members is now public:ccf.gov.members).
• --member-info on cchost can now take a third, optional file path to a JSON file containing additional member data (#1712).

Removed

• /api/schema endpoints are removed, as the same information is now available in the OpenAPI document at /api.

Deprecated

• Passing the SecurityDomain when creating a KV map is deprecated, and will be removed in a future release. This should be encoded in the table's name, with a public: prefix for public tables.
