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