6.0.0

Added

• Add logging (#112)
  • You will not be able to see log messages by default, but you can turn them on for this library by setting the DEBUG environment variable to metamask:eth-block-tracker:* or metamask:*.
• Add destroy method to block tracker classes (#106)
• Update PollingBlockTracker to support new blockResetDuration option (#103)
• Expose types that represent options to PollingBlockTracker and SubscribeBlockTracker constructors (#103)

Changed

• BREAKING: Require Node >= 14 (#113)
• BREAKING: Make BaseBlockTracker abstract (#103)
  • If you are using this class directly, you must only use PollingBlockTracker or SubscribeBlockTracker.
• BREAKING: Make options for BaseBlockTracker required (#103)
  • Subclasses must pass a set of options to super in their constructors.
• Make argument to removeAllListeners in BaseBlockTracker optional (#103)
• BREAKING: Update signatures for _start and _end in BaseBlockTracker (#103)
  • Subclasses must provide an implementation for both of these methods; they are no longer no-ops.
  • Both methods must return a promise.
• Update SubscribeBlockTracker to not pass empty newHeads parameter to eth_subscribe call (#108)
  • This change was made because OpenEthereum does not support this parameter. While we've done our best to confirm that this will not be a breaking change for other Ethereum implementations, you will want to confirm no breakages for yours.

Security

• Add @lavamoat/allow-scripts to ensure that install scripts are opt-in for dependencies (#97)
