+## Changelog
+
+### Version 3.1 - 2025-02-11 {collapsible="true"}
+
+* adds properties.h
+* adds tree.h
+* adds json.h
+* adds locale-independent string to number conversion functions
+* adds reallocarray() like functions to allocator.h
+* adds cxIterator() to create iterators over raw C arrays
+* adds cxIteratorPtr() to create iterators over raw C pointer arrays
+* adds cx_array_reallocator() and cx_array_default_reallocator
+* adds several new array and list functions
+* adds cxBufferReset()
+* adds cxBufferAppend()
+* adds cxBufferEnableFlushing() and cxBufferFlush()
+* adds CX_BUFFER_COPY_ON_WRITE and CX_BUFFER_COPY_ON_EXTEND flags
+* adds cxBufferWriteFunc and cxBufferReadFunc function pointers (for convenience)
+* adds cx_cmp_ptr()
+* adds cx_vcmp_* family of functions
+* adds cx_sprintf() and several more variants
+* adds runtime constants to read out the actual SBO sizes
+* adds improved version of UCX 2 Test framework (now a self-contained header)
+* adds cx_nmemb() utility function to common.h
+* changes that CxMap returns own CxMapIterator to save memory in CxIterator
+* changes name of cxBasicMempoolCreate() to cxMempoolCreateSimple()
+* changes all functions, for which there is no dedicated xyz_a variant,
+ to accept NULL as allocator argument (in which case a default allocator will be used)
+* changes the name of destroy functions that actually free the memory to better indicate their behavior
+* change cx_strcat variants to allow handling of ENOMEM
+* change cx_strcast() to also accept cxstring (and doing nothing in that case)
+* change the behavior of cxBufferSeek() to allow offset zero for SEEK_END
+* moves cx_compare_func typedef to compare.h
+* moves cx_szmul() to common.h
+* moves stream copy functions to new streams.h
+* removes cx_strupper() and cx_strlower() because they only do the right thing in special cases
+* removes several *_m variants of functions in string.h in favor of automatic conversion
+* removes utils.h
+* removes flag_removal function from iterator
+* removes cxMapDetach() and makes cxMapRemoveAndGet() compatible with both map variants
+* removes the API for changing the store_pointer property of collections after their creation
+* removes CMake
+* removes GTest dependency
+* removes flags to disable SBO in tests
+* removes CX_LINKED_LIST_SWAP_SBO_SIZE (it's not really an optimization for linked lists)
+* fixes cx_strcmp() and cx_strcasecmp() not being useful for lexicographic ordering
+* fixes cx_hash_key_cxstr() evaluating the argument twice
+* fixes critical bug that produced wrong results when comparing lists of different type but same size
+* ends UCX 2.1 long term support
