v0.4.2 (2026-08-21)

Added

• Components that declare source messages can translate them without engine i18n settings, can name their message language with I18n.messages_locale, and can use another component's source key through the same engine catalog.
• Browser translations can bind reactive text, attributes, and custom destinations through checked $c-tr directives and i18n.bind() callbacks.

Performance

• Repeated equal instances of a component declared with pure = True can now reuse its side-effect-free body work within one root render.
• Large component trees render faster by batching Alpine analysis in Rust, canonicalizing client graphs in Rust, caching stable ownership metadata, and avoiding transient attribute and ownership records.
• Repeated large-tree renders avoid redundant attribute-name validation, Events dispatch, replacement selection, and ownership-tree traversals.

Changed

• Rendered ownership comments now use readable eight-character revision aliases while manifests and browser APIs retain complete graph revisions.

Fixed

• Source-free i18n link units retain the masked punctuation needed to validate formatter calls when package catalogs are linked into an application.
