gecko-dev/third_party/rust/base64/RELEASE-NOTES.md

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): 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 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.

0.9.3

• Update safemem

0.9.2

• Derive Clone for DecodeError.

0.9.1

• Add support for crypt(3)'s base64 variant.

0.9.0

• decode_config_slice function for no-allocation decoding, analogous to encode_config_slice
• Decode performance optimization

0.8.0

• encode_config_slice function for no-allocation encoding

0.7.0

• STANDARD_NO_PAD config
• Base64Display heap-free wrapper for use in format strings, etc

0.6.0

• Decode performance improvements
• Use unsafe in fewer places
• Added fuzzers

0.5.2

• Avoid usize overflow when calculating length
• Better line wrapping performance

0.5.1

• Temporarily disable line wrapping
• Add Apache 2.0 license

0.5.0

• MIME support, including configurable line endings and line wrapping
• Removed decode_ws
• Renamed Base64Error to DecodeError

0.4.1

• Allow decoding a AsRef<[u8]> instead of just a &str

0.4.0

• Configurable padding
• Encode performance improvements

0.3.0

• Added encode/decode functions that do not allocate their own storage
• Decode performance improvements
• Extraneous padding bytes are no longer ignored. Now, an error will be returned.
