#15609 1f070c8 Thanks @emily-shen! - Build Containers when emitting experimental Build Output
Wrangler and the Cloudflare Vite plugin now build Dockerfile-backed Container images when experimental Build Output is enabled. Container configs are emitted under .cloudflare/output/v0/containers with local image references, while existing registry references pass through unchanged.
#15329 c4c9b75 Thanks @akshitsinha! - Evaluate Flagship flags locally during development
Flagship bindings now use the local Miniflare store by default in Wrangler and the Vite plugin, keeping development offline and isolated from production flags. Set remote: true on a binding to continue using its remote app.
Use wrangler flagship flags pull <APP_ID> to seed the store from a remote app. Flag management commands also accept --local to read and update the local store directly.
#15701 643e5cc Thanks @WillTaylorDev! - Pass Preview intent to defineWorker and upload its resolved configuration
Preview builds now evaluate programmatic Worker configuration with ctx.isPreview set to true and record that intent in Build Output. The shared Preview uploader deploys the resolved bindings and settings while preserving configured Preview base values when it creates a Preview.
