2026-06-30	2.15.1

Fixes:

- Include the object key or array index in unpack type mismatch error messages
- Reject negative string length in the 'json_pack' 's#' and '+#' formats
- Limit recursion depth in dump, equal and deep copy to prevent stack overflow

Build:

- Only export symbols starting with 'json_' and 'jansson_' from the CMake build
- Include 'jansson_private_config.h' only if 'HAVE_CONFIG_H' is enabled
- Add a configurable pkg-config install path to the CMake build
- Only use '--default-symver' when the linker supports it


2026-01-24	2.15

New features:

- Add support for realloc by adding 'json_set_alloc_funcs2',
  'json_get_alloc_funcs2'

Fixes:

- Optimize serialization
- Fix docstrings in hashtable.h

Build

- Use target-based cmake settings


2025-03-23	2.14.1

Fixes:

- Fix thread safety of encoding and decoding when 'uselocale' or
  'newlocale' is used to switch locales inside the threads

- Use David M. Gay's 'dtoa()' algorithm to avoid misprinting issues of
  real numbers that are not exactly representable as a 'double'

  If this is not desirable, use './configure --disable-dtoa' or
  'cmake -DUSE_DTOA=OFF'

Build:

- Make test output nicer in CMake based builds
- Simplify tests
