v3.11.2¶

Released on 2022-08-12.

Fixes bugs found in 3.11.1 and restructures the namespace. All changes are backward-compatible.

• Fixes the value function (broken for strings, size types, and nullptr in 3.11.0) and makes json_fwd.hpp self-contained.
• Restores using json_pointer as a key in associative containers and comparing it with strings.
• Restructures the inline namespace and allows disabling the version component, and avoids heap allocations in the BJData parser.
