29 ### Version 3.1 - 2025-02-11 {collapsible="true"}
30
31 * adds properties.h
32 * adds tree.h
33 * adds json.h
34 * adds locale-independent string to number conversion functions
35 * adds reallocarray() like functions to allocator.h
36 * adds cxIterator() to create iterators over raw C arrays
37 * adds cxIteratorPtr() to create iterators over raw C pointer arrays
38 * adds cx_array_reallocator() and cx_array_default_reallocator
39 * adds several new array and list functions
40 * adds cxBufferReset()
41 * adds cxBufferAppend()
42 * adds cxBufferEnableFlushing() and cxBufferFlush()
43 * adds CX_BUFFER_COPY_ON_WRITE and CX_BUFFER_COPY_ON_EXTEND flags
44 * adds cxBufferWriteFunc and cxBufferReadFunc function pointers (for convenience)
45 * adds cx_cmp_ptr()
46 * adds cx_vcmp_* family of functions
47 * adds cx_sprintf() and several more variants
48 * adds runtime constants to read out the actual SBO sizes
49 * adds improved version of UCX 2 Test framework (now a self-contained header)
50 * adds cx_nmemb() utility function to common.h
51 * changes that CxMap returns own CxMapIterator to save memory in CxIterator
52 * changes name of cxBasicMempoolCreate() to cxMempoolCreateSimple()
53 * changes all functions, for which there is no dedicated xyz_a variant,
54 to accept NULL as allocator argument (in which case a default allocator will be used)
55 * changes the name of destroy functions that actually free the memory to better indicate their behavior
56 * change cx_strcat variants to allow handling of ENOMEM
57 * change cx_strcast() to also accept cxstring (and doing nothing in that case)
58 * change the behavior of cxBufferSeek() to allow offset zero for SEEK_END
59 * moves cx_compare_func typedef to compare.h
60 * moves cx_szmul() to common.h
61 * moves stream copy functions to new streams.h
62 * removes cx_strupper() and cx_strlower() because they only do the right thing in special cases
63 * removes several *_m variants of functions in string.h in favor of automatic conversion
64 * removes utils.h
65 * removes flag_removal function from iterator
66 * removes cxMapDetach() and makes cxMapRemoveAndGet() compatible with both map variants
67 * removes the API for changing the store_pointer property of collections after their creation
68 * removes CMake
69 * removes GTest dependency
70 * removes flags to disable SBO in tests
71 * removes CX_LINKED_LIST_SWAP_SBO_SIZE (it's not really an optimization for linked lists)
72 * fixes cx_strcmp() and cx_strcasecmp() not being useful for lexicographic ordering
73 * fixes cx_hash_key_cxstr() evaluating the argument twice
74 * fixes critical bug that produced wrong results when comparing lists of different type but same size
75 * ends UCX 2.1 long term support
