v3.4.2

Fixed

• Resolved CS0121 overload ambiguity when passing a no-hole interpolated string (e.g. Append($"text")) to Append/AppendLine on C# 13 and earlier, by adding Append(string?) and AppendLine(string?) overloads. Reported by @SMAH1 in #283

v3.4.1

v3.1.0

Added

• Added PadLeft(ReadOnlySpan<char>, int, char) and PadRight(ReadOnlySpan<char>, int, char) methods to append padded strings without allocating additional memory (by @SMAH1 in #260)

• Optimized Replace(ReadOnlySpan<char>, ReadOnlySpan<char>) when both spans are length 1 (by @Joy-less in #241)

Added

• Added ToString(int) (by @Joy-less in #239)
• Added AsSpan(int), AsSpan(int, int), AsSpan(Range) (by @Joy-less in #239)

Changed

• Simplified IndexOf and LastIndexOf (by @Joy-less in #238)

Fixed

• Fixed IndexOf and LastIndexOf allowing out-of-bounds index when the string to find is empty (by @Joy-less in #238)
