-0.18.99 (future release)
+
+0.19 (up to commit 8948568, 2026-01-18)
========================================
Deprecated and removed features:
--------------------------------
-* none yet
+* none
New features
------------
-* none yet
+* Add support for Commodore Amiga and MorphOS
+* Allow builds with CMake 4 - sync minimum version across all CMakeLists.txt files
+* Update openssl command to work for newer versions of openssl.
+* Add support for building json-c with meson
+* Support MSVC in packages that use GNU Autoconf.
+* Add VERSIONINFO to libjson-c.dll
+* Make json_tokener_free(NULL) a no-op, to simplify cleanup paths.
+* Explicitly handle NaN values when converting to int
+* Set errno=RANGE in json_object_get_int/int64/uint64() when the source value can't be represented in the target type.
+* Make json_parse a bit more useful by adding -u (validate UTF8) and -P (specify arbitrary tokener parse flags), and read from stdin if no filename is provided.
+* Fix the apps/json_parse "-s" (strict) option so it actually does something, and default to non-strict.
+
Significant changes and bug fixes
---------------------------------
-* none yet
+* Issue #867 - also disallow control characters in keys in JSON_TOKENER_STRICT mode
+* Issue #875: cast to unsigned char so bytes above 0x7f aren't interpreted as negative, which was causing the strict-mode control characters check to incorrectly trigger.
+* Issue #881: don't allow json_tokener_new_ex() with a depth < 1
+* Fix linkhash breaking -std=c89
+* Fixing Cmake build when using clang-cl, avoids errors about redefining existing symbols
+* Fix AIX build failure - Add CMake detection for getopt.h
+* Fix bug involving supplemental code points that look like high surrogates
+* Fix runtime issue with test_util_file.c in Windows (add O_BINARY)
+* Fix macro WIN32_LEAN_AND_MEAN redefined
