v1.4.15

Changed

• Modified JSON-RPCs chain_get_era_info_by_switch_block and chain_get_era_summary to use either Key::EraInfo or Key::EraSummary as appropriate in order to provide useful responses.

v1.4.14

Added

• Node executes new prune process after executing each block, whereby entries under Key::EraInfo are removed in batches of size defined by the new chainspec option [core.prune_batch_size].
• After executing a switch block, information about that era is stored to global state under a new static key Key::EraSummary.
• Add a new JSON-RPC endpoint chain_get_era_summary to retrieve the information stored under Key::EraSummary.

Changed

• Rather than storing an ever-increasing collection of era information after executing a switch block under Key::EraInfo, the node now stores only the information relevant to that era under Key::EraSummary.
• Update openssl and openssl-sys to latest versions.

Removed

• Remove TimeDiff, Timestamp and asymmetric key functionality (moved to casper-types crate).

Fixed

• Fix issue in BlockValidator inhibiting the use of fallback peers to fetch missing deploys.

v1.4.13

Better instrumentation of branching WASM Op Codes to allow reduction of gas costs while still providing attack protection.

private-1.4.8

Integrating the 1.4.8 security fixes into private-chain.

v1.4.8

Changed:

• Update to fix security issue

private-1.4.6

Support for Private Chain configuration of 1.4.6.

v1.4.6

Changed

• Update dependencies to make use of scratch global state in the contract runtime.

v1.4.5

1.4.5

Added

• Add a temporary chainspec setting max_stored_value_size to limit the size of individual values stored in global state.
• Add a chainspec setting minimum_delegation_amount to limit the minimal amount of motes that can be delegated by a first time delegator.
• Add a chainspec setting block_max_approval_count to limit the maximum number of approvals across all deploys in a single block.
• Add a finalized_approvals field to the GetDeploy RPC, which if true causes the response to include finalized approvals substituted for the originally-received ones.

Fixed

• Include deploy approvals in block payloads upon which consensus operates.
• Fixes a bug where historical auction data was unavailable via get-auction-info RPC.

v1.4.4

Added immediate metric for commit step.
Rolled back mixed case checksum formatting for output hex.

v1.4.3

Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.

[2.0.1] - 2021-11-4

Test Support (casper-node/execution_engine_testing/test_support)

Changed

• Change the path detection logic for compiled Wasm as used by the casper-node monorepo.

Deprecated

• Deprecate the test-support feature. It had and continues to have no effect when enabled.

[2.0.0] - 2021-11-01

Test Support (casper-node/execution_engine_testing/test_support)

Added

• Provide fine-grained support for testing all aspects of smart contract execution, including:
• WasmTestBuilder for building and running a test to exercise a smart contract
• DeployItemBuilder for building a DeployItem from a smart contract
• ExecuteRequestBuilder for building an ExecuteRequest to execute a given smart contract
• AdditiveMapDiff to allow easy comparison of two AdditiveMaps
• StepRequestBuilder for building a StepRequest (generally only used by the execution engine itself)
• UpgradeRequestBuilder for building an UpgradeRequest (generally only used by the execution engine itself)
• Provide InMemoryWasmTestBuilder which will be suitable in most cases for testing a smart contract
• Provide LmdbWasmTestBuilder can be used where global state needs to be persisted after execution of a smart contract
• Provide several helper functions in utils module
• Provide several default consts and statics useful across many test scenarios

Removed

• Remove coarse-grained support and newtypes for testing smart contracts, including removal of:
• Account
• AccountHash
• Error
• Session
• SessionBuilder
• SessionTransferInfo
• TestContext
• TestContextBuilder
• Value

[1.4.4] - 2021-11-18

Casper Types (casper-node/types/)

Fixed

• Revert the accidental change to the std feature causing a broken build when this feature is enabled.

1.4.3 - 2021-11-17

1.4.2 - 2021-11-11

Casper Node (casper-node/node/)

Changed

• There are now less false warnings/errors regarding dropped responders or closed channels during a shutdown, where they are expected and harmless.
• Execution transforms are ordered by insertion order.

Removed

• The config option consensus.highway.unit_hashes_folder has been removed.

Fixed

• The block proposer component now retains pending deploys and transfers across a restart.

Execution Engine (casper-node/execution_engine/)

Changed

• Execution transforms are returned in their insertion order.

Removed

• Removed SystemContractCache as it was not being used anymore

Casper Types (casper-node/types/)

Added

• Add checksummed hex encoding following a scheme similar to EIP-55.
