10 | If you are upgrading from an earlier release such as 5.11.1, first read |
11 | the L<perl5112delta>, which describes differences between 5.11.1 and | |
12 | 5.11.2 | |

14 | =head1 Incompatible Changes | |
15 | ||
205b2220 | 16 | =head2 Filehandles are blessed directly into C<IO::Handle>, as C<FileHandle> is merely a wrapper around C<IO::Handle>. |
1f5724d9 | 17 | |
d350938a | 18 | The previous behaviour was to bless Filehandles into L<FileHandle> |
c308b6b9 | 19 | (an empty proxy class) if it was loaded into memory and otherwise |
205b2220 | 20 | to bless them into C<IO::Handle>. |

24 | =head2 Unicode version |
25 | ||
51f494cc | 26 | Perl is shipped with the latest Unicode version, 5.2, dated October 2009. See |
283b82dc | 27 | L<http://www.unicode.org/versions/Unicode5.2.0> for details about this release |
db2ed548 DG |
28 | of Unicode. See L<perlunicode> for instructions on installing and using |
29 | older versions of Unicode. | |
37e2e78e | 30 | |
8d814567 RGS |
31 | =head2 Unicode properties |
32 | ||
33 | Perl can now handle every Unicode character property. A new pod, | |
34 | L<perluniprops>, lists all available non-Unihan character properties. By | |
35 | default the Unihan properties and certain others (deprecated and Unicode | |
36 | internal-only ones) are not exposed. See below for more details on | |
37 | these; there is also a section in the pod listing them, and why they are | |
38 | not exposed. | |
39 | ||
40 | Perl now fully supports the Unicode compound-style of using C<=> and C<:> | |
41 | in writing regular expressions: C<\p{property=value}> and | |
42 | C<\p{property:value}> (both of which mean the same thing). | |
43 | ||
db2ed548 | 44 | Perl now fully supports the Unicode loose matching rules for text |
8d814567 RGS |
45 | between the braces in C<\p{...}> constructs. In addition, Perl also allows |
46 | underscores between digits of numbers. | |
47 | ||
48 | All the Unicode-defined synonyms for properties and property values are | |
49 | now accepted. | |
50 | ||
37e2e78e KW |
51 | C<qr/\X/>, which matches a Unicode logical character, has been expanded to work |
52 | better with various Asian languages. It now is defined as an C<extended | |
51f494cc | 53 | grapheme cluster>. (See L<http://www.unicode.org/reports/tr29/>). |
c670e63a KW |
54 | Anything matched previously that made sense will continue to be matched. But |
55 | in addition: | |

60 | ||
61 | C<\X> will now not break apart a C<S<CR LF>> sequence. | |
62 | ||
63 | =item * | |
64 | ||
65 | C<\X> will now match a sequence including the C<ZWJ> and C<ZWNJ> characters. | |
66 | ||
67 | =item * | |
68 | ||
69 | C<\X> will now always match at least one character, including an initial mark. | |
70 | Marks generally come after a base character, but it is possible in Unicode to | |
71 | have them in isolation, and C<\X> will now handle that case, for example at the | |
c670e63a KW |
72 | beginning of a line or after a C<ZWSP>. And this is the part where C<\X> |
73 | doesn't match the things that it used to that don't make sense. Formerly, for | |
74 | example, you could have the nonsensical case of an accented LF. | |
51f494cc KW |
75 | |
76 | =item * | |
77 | ||
78 | C<\X> will now match a (Korean) Hangul syllable sequence, and the Thai and Lao | |
79 | exception cases. | |
80 | ||
81 | =back | |
82 | ||
83 | Otherwise, this change should be transparent for the non-affected languages. | |
37e2e78e | 84 | |
8d814567 RGS |
85 | C<\p{...}> matches using the Canonical_Combining_Class property were |
86 | completely broken in previous Perls. This is now fixed. | |
87 | ||
51f494cc | 88 | In previous Perls, the Unicode C<Decomposition_Type=Compat> property and a |
8d814567 RGS |
89 | Perl extension had the same name, which led to neither matching all the |
90 | correct values (with more than 100 mistakes in one, and several thousand | |
91 | in the other). The Perl extension has now been renamed to be | |
51f494cc | 92 | C<Decomposition_Type=Noncanonical> (short: C<dt=noncanon>). It has the same |
8d814567 | 93 | meaning as was previously intended, namely the union of all the |
51f494cc | 94 | non-canonical Decomposition types, with Unicode C<Compat> being just one of |
8d814567 RGS |
95 | those. |
96 | ||
97 | C<\p{Uppercase}> and C<\p{Lowercase}> have been brought into line with the | |
98 | Unicode definitions. This means they each match a few more characters | |
99 | than previously. | |
100 | ||
101 | C<\p{Cntrl}> now matches the same characters as C<\p{Control}>. This means it | |
102 | no longer will match Private Use (gc=co), Surrogates (gc=cs), nor Format | |
103 | (gc=cf) code points. The Format code points represent the biggest | |
104 | possible problem. All but 36 of them are either officially deprecated | |
105 | or strongly discouraged from being used. Of those 36, likely the most | |
106 | widely used are the soft hyphen (U+00AD), and BOM, ZWSP, ZWNJ, WJ, and | |
107 | similar, plus Bi-directional controls. | |
108 | ||
109 | C<\p{Alpha}> now matches the same characters as C<\p{Alphabetic}>. The Perl | |
110 | definition included a number of things that aren't really alpha (all | |
51f494cc | 111 | marks), while omitting many that were. As a direct consequence, the |
8d814567 RGS |
112 | definitions of C<\p{Alnum}> and C<\p{Word}> which depend on Alpha also change. |
113 | ||
114 | C<\p{Word}> also now doesn't match certain characters it wasn't supposed | |
115 | to, such as fractions. | |
116 | ||
51f494cc KW |
117 | C<\p{Print}> no longer matches the line control characters: Tab, LF, CR, |
118 | FF, VT, and NEL. This brings it in line with the documentation. | |
8d814567 | 119 | |
51f494cc | 120 | C<\p{Decomposition_Type=Canonical}> now includes the Hangul syllables. |
8d814567 RGS |
121 | |
122 | The Numeric type property has been extended to include the Unihan | |
123 | characters. | |
124 | ||
51f494cc | 125 | There is a new Perl extension, the 'Present_In', or simply 'In', |
8d814567 | 126 | property. This is an extension of the Unicode Age property, but |
51f494cc KW |
127 | C<\p{In=5.0}> matches any code point whose usage has been determined |
128 | I<as of> Unicode version 5.0. The C<\p{Age=5.0}> only matches code points | |
129 | added in I<precisely> version 5.0. | |
8d814567 RGS |
130 | |
131 | A number of properties did not have the correct values for unassigned | |
132 | code points. This is now fixed. The affected properties are | |
133 | Bidi_Class, East_Asian_Width, Joining_Type, Decomposition_Type, | |
134 | Hangul_Syllable_Type, Numeric_Type, and Line_Break. | |
135 | ||
136 | The Default_Ignorable_Code_Point, ID_Continue, and ID_Start properties | |
51f494cc | 137 | have been updated to their current Unicode definitions. |
8d814567 RGS |
138 | |
139 | Certain properties that are supposed to be Unicode internal-only were | |
140 | erroneously exposed by previous Perls. Use of these in regular | |
51f494cc KW |
141 | expressions will now generate, if enabled, a deprecated warning message. |
142 | The properties are: Other_Alphabetic, Other_Default_Ignorable_Code_Point, | |
143 | Other_Grapheme_Extend, Other_ID_Continue, Other_ID_Start, Other_Lowercase, | |
144 | Other_Math, and Other_Uppercase. | |
8d814567 | 145 | |
8d814567 RGS |
146 | An installation can now fairly easily change which Unicode properties |
147 | Perl understands. As mentioned above, certain properties are by default | |
148 | turned off. These include all the Unihan properties (which should be | |
149 | accessible via the CPAN module Unicode::Unihan) and any deprecated or | |
150 | Unicode internal-only property that Perl has never exposed. | |
151 | ||
d350938a JV |
152 | The generated files in the C<lib/unicore/To> directory are now more |
153 | clearly marked as being stable, directly usable by applications. | |
154 | New hash entries in them give the format of the normal entries, | |
155 | which allows for easier machine parsing. Perl can generate files | |
156 | in this directory for any property, though most are suppressed. An | |
157 | installation can choose to change which get written. Instructions | |
158 | are in L<perluniprops>. | |

ecb37473 JV |
310 | settings for Windows Vista and later. Without this setting Windows |
311 | will treat C<perl.exe> as a legacy application and apply various | |
312 | heuristics like redirecting access to protected file system areas | |
313 | (like the "Program Files" folder) to the users "VirtualStore" | |
314 | instead of generating a proper "permission denied" error. | |
315 | ||
316 | For VC8 and VC9 this manifest setting is automatically generated by | |

357 | Ensure that pp_qr returns a new regexp SV each time. Resolves RT #69852. |
358 | ||
359 | Instead of returning a(nother) reference to the (pre-compiled) regexp in the | |
360 | optree, use reg_temp_copy() to create a copy of it, and return a reference to | |
361 | that. This resolves issues about Regexp::DESTROY not being called in a timely | |
362 | fashion (the original bug tracked by RT #69852), as well as bugs related to | |
363 | blessing regexps, and of assigning to regexps, as described in correspondence | |
364 | added to the ticket. | |
365 | ||
366 | It transpires that we also need to undo the SvPVX() sharing when ithreads | |
367 | cloning a Regexp SV, because mother_re is set to NULL, instead of a cloned | |
368 | copy of the mother_re. This change might fix bugs with regexps and threads in | |
369 | certain other situations, but as yet neither tests nor bug reports have | |

522 | =head1 Reporting Bugs | |
523 | ||
524 | If you find what you think is a bug, you might check the articles | |
525 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
526 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
527 | information at http://www.perl.org/ , the Perl Home Page. | |
528 | ||
529 | If you believe you have an unreported bug, please run the B<perlbug> | |
530 | program included with your release. Be sure to trim your bug down | |
531 | to a tiny but sufficient test case. Your bug report, along with the | |
532 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
533 | analysed by the Perl porting team. | |
534 | ||
535 | If the bug you are reporting has security implications, which make it | |
536 | inappropriate to send to a publicly archived mailing list, then please send | |
537 | it to perl5-security-report@perl.org. This points to a closed subscription | |
538 | unarchived mailing list, which includes all the core committers, who be able | |
539 | to help assess the impact of issues, figure out a resolution, and help | |
540 | co-ordinate the release of patches to mitigate or fix the problem across all | |
541 | platforms on which Perl is supported. Please only use this address for | |
542 | security issues in the Perl core, not for modules independently | |
543 | distributed on CPAN. | |
