What's Changed

• New chars_format::javascript format (ECMAScript DecimalLiteral): like JSON, but the integer part may be empty (.5) and the fractional part may be empty (5., 5.e3); leading zeros, inf and nan are rejected. #407
• New chars_format::javascript_sloppy format: additionally accepts sloppy-mode NonOctalDecimalIntegerLiteral (08.5 is 8.5). A legacy octal literal (0775) is rejected with the new parse_error::legacy_octal_integer_part so it can be parsed in base 8.
• Faster integer-part scanning (4-digit SWAR on GCC) and skipping the rounding-mode probe for long mantissas by @fcostaoliveira in #398
• Avoid old-style casts by @lemire in #405
• Fix compatibility with min()/max() macros by @dg0yt in #399
• Guard is_space against negative signed code units by @sahvx655-wq in #395
• docs: fix strtod function name in README by @latent-9 in #404
