+
+# v0.16.0
+- Make it easier to instantiate `pydub.AudioSegment()` directly when creating audio segments from raw audio data (without having to write it to a file first)
+- Add `pydub.AudioSegment().get_array_of_samples()` method which returns the samples which make up an audio segment (you should usually prefer this over `pydub.AudioSegment().raw_data`)

+- Allow users to specify frame rate in `pydub.AudioSegment.silent()` constructor

+# v0.15.0

+
+# v0.14.1
+- Fix a bug in `pydub.utils.mediainfo()` that caused inputs containing unescaped characters to raise a runtime error (inputs are not supposed to require escaping)
+
+# v0.14.0
+- Rename `pydub.AudioSegment().set_gain()` to `pydub.AudioSegment().apply_gain_stereo()` to better reflect it's place in the world (as a counterpart to `pydub.AudioSegment().apply_gain()`)
+
+# v0.13.0
+- Add `pydub.AudioSegment().pan()` which returns a new stereo audio segment panned left/right as specified.
+
+# v0.12.0
+- Add a logger, `"pydub.converter"` which logs the ffmpeg commands being run by pydub.
+- Add `pydub.AudioSegment().split_to_mono()` method which returns a list of mono audio segments. One for each channel in the original audio segment.
+- Fix a bug in `pydub.silence.detect_silence()` which caused the function to break when a silent audio segment was equal in length to the minimum silence length. It should report a single span of silence covering the whole silent audio segment. Now it does.
+- Fix a bug where uncommon wav formats (those not supported by the stdlib wave module) would throw an exception rather than converting to a more common format via ffmpeg/avconv
+
+# v0.11.0
+- Add `pydub.AudioSegment().max_dBFS` which reports the loudness (in dBFS) of the loudest point (i.e., highest amplitude sample) of an audio segment
+
+# v0.10.0
+- Overhaul Documentation
+- Improve performance of `pydub.AudioSegment().overlay()`
+- Add `pydub.AudioSegment().invert_phase()` which (shocker) inverts the phase of an audio segment

+
+# v0.9.5
+- Add `pydub.generators` module containing simple signal generation functions (white noise, sine, square wave, etc)
+- Add a `loops` keyword argument to `pydub.AudioSegment().overlay()` which allows users to specify that the overlaid audio should be repeated (i.e., looped) a certain number of times, or indefinitely
+
+# 0.9.4
+- Fix a bug in db_to_float() where all values were off by a factor of 2
+
+# 0.9.3
+- Allow users to set the location of their converter by setting `pydub.AudioSegment.converter = "/path/to/ffmpeg"` and added a shim to support the old method of assigning to `pydub.AudioSegment.ffmpeg` (which is deprecated now that we support avconv)
+
+# v0.9.2
+- Add support for Python 3.4
+- Audio files opened with format "wave" are treated as "wav" and "m4a" are treated as "mp4"
+- Add `pydub.silence` module with simple utilities for detecting and removing silence.
+- Fix a bug affecting auto-detection of ffmpeg/avconv on windows.
+- Fix a bug that caused pydub to only work when ffmpeg/avconv is present (it should be able to work with WAV data without any dependencies)
+
+# v0.9.1
+- Add a runtime warning when ffmpeg/avconv cannot be found to aid debugging
+
+# v0.9.0
+- Added support for pypy (by reimplementing audioop in python). Also, we contributed our implementation to the pypy project, so that's 💯
+- Add support for avconv as an alternative to ffmpeg
+- Add a new helper module `pydub.playback` which allows you to quickly listen to an audio segment using ffplay (or avplay)
+- Add new function `pydub.utils.mediainfo('/path/to/audio/file.ext')` which reports back the results of ffprobe (or avprobe) including codec, bitrate, channels, etc
