# 0.13.0
- Config methods are const
- Added `EncoderStringWriter` to allow encoding directly to a String
- `EncoderWriter` now owns its delegate writer rather than keeping a reference to it (though refs still work)
- As a consequence, it is now possible to extract the delegate writer from an `EncoderWriter` via `finish()`, which returns `Result<W>` instead of `Result<()>`. If you were calling `finish()` explicitly, you will now need to use `let _ = foo.finish()` instead of just `foo.finish()` to avoid a warning about the unused value.
- When decoding input that has both an invalid length and an invalid symbol as the last byte, `InvalidByte` will be emitted instead of `InvalidLength` to make the problem more obvious.
# 0.12.2
- Add `BinHex` alphabet
# 0.12.1
- Add `Bcrypt` alphabet
# 0.12.0
- A `Read` implementation (`DecoderReader`) to let users transparently decoded data from a b64 input source
- IMAP's modified b64 alphabet
- Relaxed type restrictions to just `AsRef<[ut8]>` for main `encode*`/`decode*` functions
- A minor performance improvement in encoding
# 0.11.0
- Minimum rust version 1.34.0
- `no_std` is now supported via the two new features `alloc` and `std`.
# 0.10.1
- Minimum rust version 1.27.2
- Fix bug in streaming encoding ([#90](https://github.com/marshallpierce/rust-base64/pull/90)): if the underlying writer didn't write all the bytes given to it, the remaining bytes would not be retried later. See the docs on `EncoderWriter::write`.
- Make it configurable whether or not to return an error when decoding detects excess trailing bits.
# 0.10.0
- Remove line wrapping. Line wrapping was never a great conceptual fit in this library, and other features (streaming encoding, etc) either couldn't support it or could support only special cases of it with a great increase in complexity. Line wrapping has been pulled out into a [line-wrap](https://crates.io/crates/line-wrap) crate, so it's still available if you need it.
- `Base64Display` creation no longer uses a `Result` because it can't fail, which means its helper methods for common
configs that `unwrap()` for you are no longer needed
- Add a streaming encoder `Write` impl to transparently base64 as you write.
- Remove the remaining `unsafe` code.
- Remove whitespace stripping to simplify `no_std` support. No out of the box configs use it, and it's trivial to do yourself if needed: `filter(|b| !b" \n\t\r\x0b\x0c".contains(b)`.
- Detect invalid trailing symbols when decoding and return an error rather than silently ignoring them.
