7 * The system has been refactored to be a pure reference counting
8 system, so sweeping / garbage collection no longer exists.
9 * Executable values and functions now include a new argument to
10 hold a context (used to implement local symbol tables and such).
11 * mpdm_adel() and mpdm_hdel() no longer return the deleted element.
12 * mpdm_aset() and mpdm_hset() no longer return the old element.
13 * mpdm_sort() sorts the array instead of returning a new one.
14 * New functions mpdm_strcat_sn(), mpdm_pokewsn(),
15 mpdm_join_s(), mpdm_split_s(), mpdm_cmp_s(), mpdm_strcat_s().
16 * Some refactoring to diminish memory usage (no more `prev'
17 pointers in the value list, less residual values).
18 * mpdm_regex() always return an array in global searches (maybe
19 an empty one) and if searching for an array of regexes (maybe
25 * mpdm_ival() now accepts numbers prefixed by `0b' as binary
27 * Similarly, mpdm_sprintf() now accepts the `%b' code to
28 print a value as a binary number.
29 * Fixed mpdm_sset() when the previous-to-last value to be
30 assigned is executable (this is bug 1114).
31 * New function mpdm_iterator().
36 * New function mpdm_sscanf().
37 * Fixed mpdm_encoding() to allow again empty strings as its
38 argument to fall back to default encoding.
39 * Improved file encoding autodetection by looking at the
40 UTF BOM marks. The detected encoding is stored in the
41 `DETECTED_ENCODING' root key.
46 * Fixed a bug when processing backslashes in the substitution
47 string in sregex(), that made them dissappear if they were
48 not escaping an ampersand.
49 * Fixed a bug in win32 globbing.
50 * The dump_1() function is now pluggable.
51 * New function mpdm_chdir().
56 * The environment is stored in a hash called ENV in mpdm_root().
57 * Under win32, the LANG environment variable is hand-built if
59 * If the third argument to sregex() is a hash, the values can
60 now also be executable ones.
61 * New internal flag for values to mark them as deleted.
66 * The mpdm_regex() function now accepts a new flag, `g', to match
67 globally; in this case, an array of matches are returned instead
69 * The mpdm_stat() function now returns a 14 element array, with a
70 newly #13 argument containing the canonicalized file name, if
71 the underlying system supports it.
72 * A bunch of embedded charset encoders have been implemented for
73 iso8859-1, utf-16 and utf-32 with or without BOM autodetection.
78 * API Changes; const has been added wherever possible.
83 * The hashing function has changed to a less accurate but faster one.
84 * There is a new, adaptive way of sweeping: if default_sweep if set
85 to a negative value (different from -1), it's used as a divisor
86 of the total count of values; this will be the number of values
87 that will be swept on each call to mpdm_sweep(0). This way, the
88 number of swept values depend on the total count.
89 * New functions mpdm_set_ival() and mpdm_set_rval().
90 * New function mpdm_get_filehandle().
95 * Components of a compact symbol can be executable, apart from
97 * mpdm_cmp() is optimized to return 0 when comparing the same value.
102 * mpdm_cmp() now correctly compares NULL and NULL as equal.
103 * %c in mpdm_sprintf() now works with Unicode (wchar_t) characters.
104 * The substitution string in mpdm_sregex() now can include the
105 special character & to select the matched string. To include a
106 literal &, escape it with \.
