The light scanner (used when project rules are disabled) is now faster by only scanning the parts of the project relevant to the files you specify, rather than always scanning from the root. Type inference for the noFloatingPromises rule has improved from ~75% to ~85% coverage, with added support for getters, call signatures, and comma operators. Seven new lint rules have been added including noAlert, noImplicitCoercion, noMagicNumbers, noMisusedPromises, noUnassignedVariables, useReadonlyClassProperties, and useUnifiedTypeSignature. Notable bug fixes address nested configuration file ignoring and root configuration inheritance. The roadmap ahead includes stabilizing HTML support, expanding to Vue, Svelte, Astro, and Angular, and beginning Markdown support. ## Full article daily.dev links to this article rather than hosting it.
