By default, allowFinally is set to false, meaning that this is not allowed unless returned.

someFunction().catch(() => { /* ... */ }).finally(() => { /* ... */ });

While this is allowed:

someFunction().catch(() => { /* ... */ });

or

return someFunction().catch(() => { /* ... */ }).finally(() => { /* ... */ });

After this change, the first example is allowed as well.

That is a strange default. What does finally have to do with remembering to catch? Bizarre.

resolvePattern and rejectPattern are set to ^_?resolve$ and ^_?reject$ by default respectively, meaning that the parameters passed to a Promise constructor function must be named exactly resolve, reject, or _resolve, _reject.

This change allows for an optional suffix after resolve and reject, for example resolvePromise or rejectPromise, which can be useful when promises are nested.
