• Make all methods of deprecated AsciiExt except is_ascii() available as inherent methods in std-mode.
• Compile without warnings on Rust 1.26.0
• Acknowledge that the crate doesn't compile on Rust < 1.8.0 (cannot be fixed without breaking changes).

Version 0.8.6 (2017-07-02)

• Implement AsRef<u8> for AsciiString.

Version 0.8.4 (2017-04-18)

• Fix the tests when running without std.

Version 0.8.3 (2017-04-18)

• Bugfix: <AsciiStr as AsciiExt>::to_ascii_lowercase did erroneously convert to uppercase.

Version 0.8.2 (2017-04-17)

• Implement IntoAsciiString for &'a str and &'a [u8].
• Implement the quickcheck::Arbitrary trait for AsciiChar and AsciiString. The implementation is enabled by the quickcheck feature.

Version 0.8.1 (2017-02-11)

• Add Chars, CharsMut and Lines iterators.
• Implement std::fmt::Write for AsciiString.

Version 0.8.0 (2017-01-02)

Breaking changes:

• Return FromAsciiError instead of the input when AsciiString::from_ascii() or into_ascii_string() fails.
• Replace the no_std feature with the additive std feature, which is part of the default features. (Issue #29)
• AsciiChar::is_*() and ::as_{byte,char}() take self by value instead of by reference.

Additions:

• Make AsciiChar comparable with char and u8.
• Add AsciiChar::as_printable_char() and the free functions caret_encode() and caret_decode().
• Implement some methods from AsciiExt and Error (which are not in libcore) directly in core mode:
  • Ascii{Char,Str}::eq_ignore_ascii_case()
  • AsciiChar::to_ascii_{upper,lower}case()
  • AsciiStr::make_ascii_{upper,lower}case()
  • {ToAsciiChar,AsAsciiStr}Error::description()

• Fix the implementation of AsciiExt::to_ascii_lowercase() for AsciiChar converting to uppercase. (introduced in 0.7.0)

Version 0.7.0 (2016-06-25)

• Add from[_ascii]_unchecked methods.
• Replace from_bytes with from_ascii in method names.

• Implement AsciiExt without the unstable Cargo feature flag, which is removed.
• Require Rust 1.9 or later.
• Add #[no_std] support in a Cargo feature.
• Implement From<{&,&mut,Box<}AsciiStr> for [Ascii], [u8] and str

• Implement AsMut<AsciiStr> for AsciiString.
