New Features

Feature Change Description

Map and StringBlock parsing optimization Reduces the number of memory reallocations during parsing by predicting the number of consecutive elements (lookahead) and pre-allocating capacity. For Map fields, InsertNodeWithoutResizeCheck is used to skip redundant capacity expansion checks. For Repeated String fields, AppendString is introduced to replace ReadString, and the StringBlock TLS cache is enabled to lower memory allocation overhead.

C++23 resize_and_overwrite support Uses the C++23 standard resize_and_overwrite method in AppendPartialToString to avoid unnecessary zero-initialization, thereby improving serialization performance. This feature is automatically enabled when supported by the compiler.

Feature	Change Description
Map and StringBlock parsing optimization	Reduces the number of memory reallocations during parsing by predicting the number of consecutive elements (lookahead) and pre-allocating capacity. For Map fields, `InsertNodeWithoutResizeCheck` is used to skip redundant capacity expansion checks. For Repeated String fields, `AppendString` is introduced to replace `ReadString`, and the StringBlock TLS cache is enabled to lower memory allocation overhead.
C++23 `resize_and_overwrite` support	Uses the C++23 standard `resize_and_overwrite` method in `AppendPartialToString` to avoid unnecessary zero-initialization, thereby improving serialization performance. This feature is automatically enabled when supported by the compiler.
