    🔋 Features

    💥 BREAKING CHANGES

    • 🔀 mergeScan: mergeScan will no longer emit its inner state again upon completion.
    • pairs: pairs will no longer function in IE without a polyfill for Object.entries. pairs itself is also deprecated in favor of users just using from(Object.entries(obj)).
    • zip: Zipping a single array will now have a different result. This is an extreme corner-case, because it is very unlikely that anyone would want to zip an array with nothing at all. The workaround would be to wrap the array in another array zip([[1,2,3]]). But again, that's pretty weird.
    • count: No longer passes source observable as a third argument to the predicate. That feature was rarely used, and of limited value. The workaround is to simply close over the source inside of the function if you need to access it in there.
