- @pezkuwi/dev, dev-test, dev-ts ^0.86.3 - rethrown errors carry the original as `cause` (hw-ledger, address decode) - optional chain in isEthereumAddress, includes() in bip39 validation - logger calls the lazy formatter through a typed function - x-global: an assertion to the type the value already has removed, with the comment and directive that explained it - type-only re-exports of modules that emit no JavaScript - disable directives renamed for the new rule names, or removed where the rule no longer reports
