v0.4.0

Breaking Changes

1. Fixed bug: Number exponent parsing (commit cc3873c):
   • Breaking because some lexical::Expect enum members are renamed.
   • Fixed uppercase 'E' not being recognized as exponent character
   • Improved error reporting for number parsing edge cases
2. Added more convenience methods to Token (commit edcb726):
   • Breaking because some Token::is_* methods were renamed for better precision.
   • Added new convenience methods: Token::is_literal, Token::is_pseudo, Token::is_terminal
3. Removed mut from &self in Content::unescaped (commit 3287766):
   • Soft breaking change because it could cause compiler warnings to sprout, and that can break builds that prohibit warnings.
   • This makes the Content interface cleaner and easier to use.

Material Non-Breaking Changes

1. Fixed bug: Error message parts ran together due to no space (commit d46256a):
   • Fixed missing space in error messages between expected character and token context
