* docs(README): update FAQ a bit ([f22f09c](https://github.com/staltz/xstream/commit/f22f09c))

### BREAKING CHANGE

* ![maybe
will](https://img.shields.io/badge/will%20it%20affect%20me%3F-maybe%20will-yellow.svg)
This changes the behavior of most xstream code because errors are no
longer swallowed. When you update xstream to this version, you may
experience new errors thrown that you haven't seen before. Upgrade
carefully, keeping in mind that these thrown errors were always there,
but only now are surfaced.
* ![maybe won't](https://img.shields.io/badge/will%20it%20affect%20me%3F-maybe%20won't-yellowgreen.svg)
This is likely a breaking change for people using flattenSequentially,
specially given that xstream core was fixed so that errors are not swallowed.
Most flattenSequentially code should still work, but upgrade carefully anyway.


<a name="8.0.0"></a>

* docs(README.md): update listener to only require next ([a07e5c9](https://github.com/staltz/xstream/commit/a07e5c9))



<a name="7.0.0"></a>
## 7.0.0 (2016-10-24)

* chore(package): release new version ([1a6fec0](https://github.com/staltz/xstream/commit/1a6fec0))
* refactor(FilterMap): avoid calling super method ([8980511](https://github.com/staltz/xstream/commit/8980511))
* fix(map): remove map+map fusion optimization ([1ca6a5c](https://github.com/staltz/xstream/commit/1ca6a5c)), closes [#98](https://github.com/staltz/xstream/issues/98) [#108](https://github.com/staltz/xstream/issues/108) [#93](https://github.com/staltz/xstream/issues/93) [#98](https://github.com/staltz/xstream/issues/98) [#108](https://github.com/staltz/xstream/issues/108) [#93](https://github.com/staltz/xstream/issues/93)
* fix(MemoryStream): fix a leaking execution bug ([47e67ff](https://github.com/staltz/xstream/commit/47e67ff)), closes [#53](https://github.com/staltz/xstream/issues/53)


### BREAKING CHANGE

* This change will remove map+map fusions. Your application code may or
may not rely on the bugs that map+map fusion caused, so we advise to
update carefully, testing your application code as you go. Generally
this is very straightforward and safe to update, as there are no visible
API changes.
* This is generally safe to update, but note that the behavior around
MemoryStream, startWith, take, imitate etc may have slightly changed, so
it is recommended to run tests on your application and see if it is
working, in case your application code was relying on buggy behavior.

## 6.1.0 (2016-08-22)

* chore(package): release new version ([4a27bd5](https://github.com/staltz/xstream/commit/4a27bd5))

## 6.0.0 (2016-08-20)

* chore(package): release new version ([c68e545](https://github.com/staltz/xstream/commit/c68e545))
* fix(core): teardown and stop producer before complete/error ([ec8d6e8](https://github.com/staltz/xstream/commit/ec8d6e8)), closes [#91](https://github.com/staltz/xstream/issues/91)


### BREAKING CHANGE

* in this version, when a stream completes or errors, its producer has already been
stopped. In previous versions, the stream first completes, propagates the complete to other
listeners and operators, and then its producer is stopped. You may barely notice this breaking
change when updating your code. Most existing code will still work like before.

### BREAKING CHANGE

* combine() now takes only streams as argument, no more project function. combine() will return an
stream that emits arrays of the collected values from each input stream. To transform that array,
you should now use map() operator after combine(), to take the array of collected values and return
a combination value. See tests for examples.
* MimicStream and xs.createMimic() were removed entirely. The imitate() method now exists on every
Stream instance. To use the proxy stream technique, use xs.create() to create the proxy, then call
proxy.imitate(other).

### BREAKING CHANGE

* debug() now returns a MemoryStream if the input was also a MemoryStream.
endWhen() now returns a MemoryStream if the input was also a MemoryStream.
fold() now returns always a MemoryStream, not Stream.
imitate() only works on conventional Stream, will throw error on
MemoryStream.
map() now returns a MemoryStream if the input was also a MemoryStream.
mapTo() now returns a MemoryStream if the input was also a MemoryStream.
replaceError() now returns a MemoryStream if the input was also a MemoryStream.

### BREAKING CHANGE

* flattenConcurrently must be separately imported as an extra operator and
used with .compose()
* imitate() method on Stream removed. New type introduced: MimicStream,
which can be created through xs.createMimic(). A MimicStream has the
method imitate(), which has the same API as before, but imitate does not
trigger any Stream/Producer to start.
* Usage of flattenSequentially have changed, from
compose(flattenSequentially()) to compose(flattenSequentially) and from
compose(pairwise()) and compose(pairwise).
