What's new

v0.5.3

Features / Improvements

  • Change datatype of msgSender and signature fields to string everywhere (such as STF args and ActionParams interface).

Bug Fixes

  • Fix ordering of properties in Domain type returned from MicroRollupResponse.config.domain.
  • Fix a bug where the L1 listener would at times run into "filter not found" error.

v0.5.2 (and CLI v0.1.2)

Breaking Changes

Features / Improvements

  • Micro-rollups can now be ran in "Sandbox" mode, without registration. The new config changes removes dependencies on deployment.json and stackrApp fields.
  • Expose emit in block hooks as well (previously it was available only in STFs). Learn more.
  • Add ability to unsubscribe or inspect/list active listeners to MRU events.
  • Perform C2, C3A and C3B syncs for stale blocks on MRU start-up. This is useful to quickly sync latest states if you re-run the MRU after some downtime.
  • Add previousState, previousStateRoot and executionHooksLogs fields to ExecutorEvents.EXECUTE_BLOCK event payload (ExecuteBlockEventArgs).
  • The sequencer.tick() method exposed in MicroRollupResponse now returns a boolean value indicating whether a new block was sequenced or not.
  • [CLI] New verify command: Verify that the source state machine binary matches with the registered binary on AppInbox. Learn more.

Bug Fixes

  • Fixes a bug where it was possible to force create an empty block by returning an empty list of actions from sequencer strategy.
  • [CLI] Registering app subsequently won't fail if hash values match.
  • [Playground] Fix state rendering for non-JSON state.

v0.5.1 (and CLI v0.1.1)

  • [SDK] fix: get missing block.batchInfo from actions.query()
  • [CLI] feat: Add Windows support for stackr CLI commands and improve error handling.
  • [CLI] feat: add --envFile flag to all commands to load environment variables from a different file than .env

v0.5.0 (and CLI v0.1.0)

Upgrade guide: here.

Breaking Changes

  • Blocks are now rolled up into batches by Vulcan every some fixed interval. Therefore, C3A and above confirmation levels are now received on the batch level from Vulcan and L1. Learn more.
  • State Updates are now stored on the Block level and not Action level. In case of a chain revert, the state reverts to the last block having status equal to or higher than Sequenced.
  • Renamed batchSize and batchTime fields in StackrConfig to blockSize and blockTime respectively.

Features / Improvements

  • Pre and post Block execution hooks. Learn more.
  • Ability to create empty blocks by setting sequencer.enableEmptyBlocks to true in StackrConfig.
  • Add logs and errors fields to ActionExecutionStatusEventArgs interface.
  • Make syncer.slotTime an optional field (in StackrConfig) having a default value of max(1000, blockTime) ms. If provided value is less than 1000 ms, it defaults to max(1000, blockTime) ms too.
  • Add C1X as a new action confirmation level that represents failed execution.
  • [CLI] Use dynamic linking for reduced Wasm binary size.

Bug Fixes

  • Prevent concurrent sequencer ticks.
  • Prevent concurrent Vulcan block submission ticks.
  • Fix some types not being exported correctly from the build.

v0.4.3

  • [SDK] On MRU bootup, if SDK version does not meet Vulcan's minimum SDK supported version requirement then the latest state is dumped in a JSON file. This is useful to restore state in a new MRU deployment.

v0.4.2 (and CLI v0.0.20)

Features

  • [SDK] Expose emit method in STF that can be used to record custom logs. Learn more.
  • [SDK] Add fields logs and errors to SerializedAction.
  • [SDK] Expose waitFor method in the SerializedAcknowledgement object returned from submitAction.

Improvements

  • [CLI] Minified bundled JS file to optimize Wasm binary size.
  • [SDK] Removed redundant state computation to optimize Wasm execution.

v0.2.18-alpha to v0.4.1, CLI v0.0.19 and more

SDK

Breaking Changes

Features
