Version 0.16.0

What's Changed

Breaking Changes

• Renamed functions to more clearly express what they do and make naming conflicts with local variables less likely:
  • computed() -> createComputed()
  • effect() -> createEffect()
  • state() -> createState()
  • store() -> createStore()
  • watch() -> createWatcher() and watcher.off() -> watcher.unwatch()
• Changed store events from CustomEvent to light-weight change notifications:
  • store.addEventListener('store-*', handler) -> store.on('*', handler)
  • store.removeEventListener('store-*', handler) -> cleanup function returned from .on() handler
  • Change notification callbacks receive the former details as the only parameter, no more event involved
• Changed parameters of createComputed() to allow for reducer-like capabilities:
  • Computed callback now receives old value as first parameter, pushing AbortSignal for async callback to second parameter
  • Optional second parameter for initial value

New Features

• Add reducer-like capabilities to createComputed for accumulative computed signals
• Basic input validation with more descriptive error messages for all signal types and effects

Tests

• Updated test cases to reflect API changes
• Tests covering accumulative computed signals, more edge cases and input validation

Documentation

• Updated README to document accumulative computed signals and reflect API changes
• New AI-targeted documentation files:
  • .ai-context.md
  • .cursorrules
  • CLAUDE.md
  • .github/copilot-instructions.md
