+# 0.22.0
+
+- `DecodeSliceError::OutputSliceTooSmall` is now conservative rather than precise. That is, the error will only occur if the decoded output _cannot_ fit, meaning that `Engine::decode_slice` can now be used with exactly-sized output slices. As part of this, `Engine::internal_decode` now returns `DecodeSliceError` instead of `DecodeError`, but that is not expected to affect any external callers.
+- `DecodeError::InvalidLength` now refers specifically to the _number of valid symbols_ being invalid (i.e. `len % 4 == 1`), rather than just the number of input bytes. This avoids confusing scenarios when based on interpretation you could make a case for either `InvalidLength` or `InvalidByte` being appropriate.
+- Decoding is somewhat faster (5-10%)
