0.2.0 - 2026-08-12

Changed

• Requires juice ^1.6.0.
• Declared concurrency for every event. Initialization and refresh are droppable; fetched updates, failures, and override mutations are sequential. Overlapping refresh requests now share one remote fetch.

0.1.0 - 2026-05-28

Added

• Initial release.
• FlagsBloc — feature flags / remote config with per-flag selective rebuilds: a widget bound to FlagsGroups.flag('x') rebuilds only when that flag's value changes. A fetch diffs old vs new and emits only the changed flags' groups.
• FlagsSource — vendor seam (fetch() + optional changes() stream), so Firebase Remote Config / LaunchDarkly / an endpoint / a local map are all just implementations. Default StaticFlagsSource (in-memory).
• Layered resolution — defaults < fetched < overrides; reads always resolve via typed accessors boolFlag/stringFlag/intFlag/doubleFlag/ json<T>.
• Fail-loud, read-safe fetch — a failure surfaces in state.error (logged), while reads keep falling back to last-known/defaults.
• Local overrides — setFlagOverride/clearFlagOverride (dev toggles).
• Live updates — subscribes to source.changes() when provided.
• Rebuild groups — flags:flag:<key>, flags:any, flags:status.
