# promises 1.3.2
|
|
|
|
* Fixed bug introduced in 1.3.1, where promise domains that are active at promise resolution time stay active during handler callback, even if they weren't active when the handler was registered. This was causing stack overflow for long promise chains with many active promise domains. (#115)

# promises 1.3.1

* Fixed bug where promise domains were forgotten when handlers were registered from within other handlers. (#110)

|
* `is.promising` is now an S3 method. (#104)

* `future_promise()` received a speed improvement when submitting many requests with a minimal number of `{future}` workers. If `future_promise()` runs out of available `{future}` workers, then `future_promise()` will preemptively return for the remainder of the current `{later}` execution. While it is possible for `{future}` to finish a job before submitting all of the `future_promise()` requests, the time saved by not asking `{future}`'s worker availability will be faster overall than if a few jobs were submitted early. (#78)

|
* Fixed #86: `future_promise()` spuriously reports unhandled errors. (#90)
|
|
|
|
* Move `{fastmap}` from `Suggests` to `Imports` for better `{renv}` discovery. (#87)

# promises 1.2.0.1

* Added `future_promise()` which returns a `promise` that executes the expression using `future::future()`. `future_promise()` should (typically) be a drop-in replacement for any `future::future()` function call. `future_promise()` will not execute `future` work faster than `future::future()`, but `future_promise()` will only submit `future` jobs if a worker is available. If no workers are available, `future_promise()` will hold the expression information in a `promise` until a worker does become available to better take advantage of computing resources available to the main R session. For more information, please see the [`future_promise()` article](https://rstudio.github.io/promises/articles/future_promise.html). (#62)

|
* Added visibility support for `Promise$then(onFulfilled)`. (#59)

# promises 1.1.1

* Fix handling of FutureErrors during `future::resolved()` and `future::value()` by discarding the corrupt future. (#37)

# promises 1.1.0

|
|
* Fixed #49: `promise_all()` previously did not handle `NULL` values correctly. (#50))
|
|
|
|
* `new_promise_domain` now takes a `wrapOnFinally` argument, which can be used to intercept registration of `finally()`. Previous versions treated `finally` as passing the same callback to `then(onFulfilled=..., onRejected=...)`, and ignoring the result; for backward compatibility, promise domains will still treat `finally` that way by default (i.e. if `wrapOnFinally` is `NULL`, then `finally` will result in `wrapOnFulfilled` and `wrapOnRejected` being called, but if `wrapOnFinally` is provided then only `wrapOnFinally` will be called).
