Boa v0.18 is out after 7 months of development. It has improved conformance (from 79.36% to 85.03% in Test262), with 3,550 more tests passed and ignored tests decreased. The website was redesigned with a new logo. Highlights include being on test262.fyi, work on the Temporal API, improved RegExp, SharedArrayBuffer + Atomics, Intl updates, builtins updates, APIs updates, and optimizations.

• test262.fyi: Listed on a daily runner of Test262 with other engines.
• Temporal: Work on a new set of built-in objects for date and time, still experimental.
• RegExp: Improved implementation with support for various features.
• SharedArrayBuffer + Atomics: Allows orchestrating contexts on separate threads.
• Intl updates: Intl.PluralRules and a prototype of Intl.NumberFormat implemented.
• Builtins updates: Small changes and additions to existing builtins.
• APIs updates: Experimental features, HostDefined fields, Class redesign, runtime limits, synthetic modules, async eval, and JsErasedError.
• Optimizations: Inline Caching improves performance based on Object Shapes.
• Road to 1.0: Aiming for a 1.0 release with focus on API and performance.
• How to support: Donate to Open Collective or contribute by asking for issues, improving web presence, or documenting the engine.

Thank you to all contributors.
