Changed

• ValueStringBuilder.Concat uses params ReadOnlySpan<T> to reduce boxing and improve performance.

v2.4.1

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

v2.4.0

Added

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

Changed

• Optimized and simplified Replace (by @Joy-less in #238)
• 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)

v2.3.1

Changed

• Optimized when the internal buffer should grow. Fixed by @Aniobodo.

v2.3.0

Added

• Added Equals(ReadOnlySpan<char>, StringComparison) (by @Joy-less in #234)

Changed

• Improved Equals(ReadOnlySpan<char>) (by @Joy-less in #234)
• Added performance short-circuit when span is empty in Append(ReadOnlySpan<char>), AppendSpan(int), Insert(int, ReadOnlySpan<char>) in #233 (by @Joy-less)

v2.2.0

Added

• Added TrimPrefix(ReadOnlySpan<char>, StringComparison) (by yours truly (@Joy-less) in #226)
• Added TrimSuffix(ReadOnlySpan<char>, StringComparison) (also by yours truly (@Joy-less) in #226)
• Added Insert(int, char) overload (by yours truly (@Joy-less) in #225)

v2.1.0

Added

• Added Replace(Rune, Rune) overload
• Added Replace(Rune, Rune, int, int) overload

• Added AppendJoin<T>(Rune, IEnumerable<T>) overload

Removed

• Support for net6.0 and net7.0 was removed.

• Added OverloadResolutionPriority for Span overload for the ctor to keep the current behavior. Reported by [@nsentinel])(https://github.com/nsentinel) in #210.
• Optimised AppendLine(scoped ReadOnlySpan<char>) by avoiding allocating a new string
• Removed erroneous null check in AppendJoin<T>(ReadOnlySpan<char>, IEnumerable<T>)
