16 =item 2.121 (Aug 24 2003)
18 Backport to 5.6.1 by Ilya Martynov <ilya@martynov.org>.
20 =item 2.11 (unreleased)
22 C<0> is now dumped as such, not as C<'0'>.
24 qr// objects are now dumped correctly (provided a post-5.005_58)
27 Implemented $Data::Dumper::Maxdepth, which was on the Todo list.
28 Thanks to John Nolan <jpnolan@Op.Net>.
30 =item 2.101 (30 Apr 1999)
32 Minor release to sync with version in 5.005_03. Fixes dump of
35 =item 2.10 (31 Oct 1998)
37 Bugfixes for dumping related undef values, globs, and better double
38 quoting: three patches suggested by Gisle Aas <gisle@aas.no>.
40 Escaping of single quotes in the XS version could get tripped up
41 by the presence of nulls in the string. Fix suggested by
42 Slaven Rezic <eserte@cs.tu-berlin.de>.
44 Rather large scale reworking of the logic in how seen values
45 are stashed. Anonymous scalars that may be encountered while
46 traversing the structure are properly tracked, in case they become
47 used in data dumped in a later pass. There used to be a problem
48 with the previous logic that prevented such structures from being
51 Various additions to the testsuite.
53 =item 2.09 (9 July 1998)
55 Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>.
57 =item 2.081 (15 January 1998)
59 Minor release to fix Makefile.PL not accepting MakeMaker args.
61 =item 2.08 (7 December 1997)
63 Glob dumps don't output superflous 'undef' anymore.
65 Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with
66 overloaded strings in recent perls, and his new testsuite.
70 A separate flag to always quote hash keys (on by default).
72 Recreating known CODE refs is now better supported.
74 Changed flawed constant SCALAR bless workaround.
76 =item 2.07 (7 December 1996)
78 Dumpxs output is now exactly the same as Dump. It still doesn't
79 honor C<Useqq> though.
81 Regression tests test for identical output and C<eval>-ability.
83 Bug in *GLOB{THING} output fixed.
85 Other small enhancements.
87 =item 2.06 (2 December 1996)
89 Bugfix that was serious enough for new release--the bug cripples
90 MLDBM. Problem was "Attempt to modify readonly value..." failures
91 that stemmed for a misguided SvPV_force() instead of a SvPV().)
93 =item 2.05 (2 December 1996)
95 Fixed the type mismatch that was causing Dumpxs test to fail
98 GLOB elements are dumped now when C<Purity> is set (using the
101 The C<Freezer> option can be set to a method name to call
102 before probing objects for dumping. Some applications: objects with
103 external data, can re-bless themselves into a transitional package;
104 Objects the maintain ephemeral state (like open files) can put
105 additional information in the object to facilitate persistence.
107 The corresponding C<Toaster> option, if set, specifies
108 the method call that will revive the frozen object.
110 The C<Deepcopy> flag has been added to do just that.
112 Dumper does more aggressive cataloging of SCALARs encountered
113 within ARRAY/HASH structures. Thanks to Norman Gaywood
114 <norm@godel.une.edu.au> for reporting the problem.
116 Objects that C<overload> the '""' operator are now handled
117 properly by the C<Dump> method.
119 Significant additions to the testsuite.
123 =item 2.04beta (28 August 1996)
125 Made dump of glob names respect C<Useqq> setting.
127 [@$%] are now escaped now when in double quotes.
129 =item 2.03beta (26 August 1996)
131 Fixed Dumpxs. It was appending trailing nulls to globnames.
132 (reported by Randal Schwartz <merlyn@teleport.com>).
134 Calling the C<Indent()> method on a dumper object now correctly
135 resets the internal separator (reported by Curt Tilmes
136 <curt@ltpmail.gsfc.nasa.gov>).
138 New C<Terse> option to suppress the 'C<VARI<n> = >' prefix
139 introduced. If the option is set, they are output only when
140 absolutely essential.
142 The C<Useqq> flag is supported (but not by the XSUB version
145 Embedded nulls in keys are now handled properly by Dumpxs.
147 Dumper.xs now use various integer types in perl.h (should
148 make it compile without noises on 64 bit platforms, although
149 I haven't been able to test this).
151 All the dump methods now return a list of strings in a list
155 =item 2.02beta (13 April 1996)
157 Non portable sprintf usage in XS code fixed (thanks to
158 Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>).
161 =item 2.01beta (10 April 1996)
163 Minor bugfix (single digit numbers were always getting quoted).
166 =item 2.00beta (9 April 1996)
168 C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version
173 MLDBM example removed (as its own module, it has a separate CPAN
176 Fixed bugs in handling keys with wierd characters. Perl can be
177 tripped up in its implicit quoting of the word before '=>'. The
178 fix: C<Data::Dumper::Purity>, when set, always triggers quotes
181 Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals
182 is busted. His patch added.
184 Dead code removed, other minor documentation fixes.
187 =item 1.23 (3 Dec 1995)
191 Several folks pointed out that quoting of ticks and backslashes
192 in strings is missing. Added.
194 Ian Phillipps <ian@pipex.net> pointed out that numerics may lose
195 precision without quotes. Fixed.
198 =item 1.21 (20 Nov 1995)
200 Last stable version I can remember.
