Version 0.11.0

Version 0.11.0

Breaking Changes

• Async computed signals no longer return undefined while not resolved, but a Symbol UNSET typed as the type of the signal.
• Computed signals no longer return the last cached value if an error occurred but instead re-throw the error.

New Features

• Case matching syntax for effect():
  • Instead of a single callback, first parameter can be an object with ok (happy path, required), err (error handling, optional) and nil (unset value, optional) keys and callbacks to handle each case.
  • Rest parameters can be signal variables, for which Cause & Effect will catch errors or unset values and pass their values as parameters to the ok callback if all is well.

Bugfixes

• Memoized computed signals with an unchanged value block propagation of upstream changes now correctly.
• Prevent circular dependencies if iteration counts exceeds 1000 runs. (Cause & Effect allows circular dependencies that settle at some point, but we prevent it now when the number of iterations reach a dimension that can hardly be intentional.)
