+[v0.1.0-a3]: https://github.com/althonos/pyhmmer/compare/v0.1.0-a2...v0.1.0-a3
+
+### Added
+- `TextSequence` and `DigitalSequence` representing a `Sequence` in a given mode.
+- E-value properties to `Hit` and `Domain`.
+- `TopHits` now stores a reference to the pipeline it was obtained from.
+- `Pipeline.Z` and `Pipeline.domZ` properties.
+- Experimental pickling support to `Alphabet`.
+- Experimental freelist to `Sequence` class to avoid allocation bottlenecks when iterating on a `SequenceFile` without recycling sequence buffers.
+
+### Changed
+- Made `Sequence` an abstract base class.
+- Additional `Pipeline` parameters can be passed as keyword arguments to `pyhmmer.hmmsearch`.
+- `SequenceFile.read` can now be configured to skip reading the metadata or the content of a sequence.
+
+### Removed
+- Redundant `SequenceFile` methods.
+
+### Fixed
+- `doctest` loader crashing on Python 3.5.
+- `TopHits.threshold` segfaulting when being called without prior `Tophits.sort` call
+- Unknown `format` argument to `SequenceFile` constructor not raising the right error.
