v0.38 Fri, 23 Jun 2017 07:52:20 +0200 moocow

v0.33 Tue, 03 Jan 2017 14:20:07 +0100 moocow
	+ fixed bogus reverse-ordering of sub-objects in DDC::PP::Object::Descendants()
	  - partly due to stack vs. queue confusion in DDC::PP::Object::Descendants() itself
	  - partly due to non-deterministic default DDC::PP::Object::Children() implementation
	  - fix overrides Children() for order-dependent types (CQBinOp, CQCount)

v0.29 Fri, 30 Sep 2016 12:37:07 +0200 moocow
	+ fix for DDC::PP::DisownChildren()

v0.28 Thu, 18 Aug 2016 10:39:33 +0200 moocow
	+ added ddc-query.perl -[no]bench-clear-cache and -bench-seconds options
	+ added sanity checks for DDC::Any::import() method (+tests in 10d_any_import_multi.t)
	  - avoid "Recursive inheritance detected in package 'Exporter'" errors on multiple import / use

v0.27 Mon, 11 Jul 2016 10:42:28 +0200 moocow
	+ set MIN_PERL_VERSION = v5.10.0 for yyqlexer regex /p modifier

v0.26 Thu, 07 Jul 2016 15:47:04 +0200 moocow

	+ updated module metadata

v0.23 Wed, 06 Jul 2016 15:24:54 +0200 moocow
	+ added DDC::PP hierarchy: pure-perl simulation of DDC::XS classes (updated for DDC::XS v0.13 / ddc v2.0.43)
	  - removed old DDC::Query subtree (deprecated since pre-v0.11/r159/2014-03-27, now superseded by DDC::XS, DDC::PP)
	+ added DDC::Any package to wrap DDC::XS (if available) or DDC::PP (if requested or as fallback)

v0.22 Wed, 15 Jun 2016 09:25:38 +0200 moocow
	+ removed // operator (perl >= v5.10.0)
	  - apparently the 'require' in DDC/Concordance.pm wasn't catching
	  - caused cpantesters failures for perl v5.8.x, e.g. http://www.cpantesters.org/cpan/report/2ad78a32-31ff-11e6-aa87-16280081755b
	  - also likely responsible for failed 4add1b26-3173-11e6-99be-4eefed1f9a26

v0.21 Tue, 14 Jun 2016 08:52:30 +0200 moocow
	+ added __END__ keyword before PODs in pm files

v0.20 Tue, 29 Sep 2015 09:09:10 +0200 moocow

v0.18 Mon, 28 Sep 2015 14:50:46 +0200 moocow

v0.17_001 Fri, 25 Sep 2015 11:04:52 +0200 moocow
	+ renamed distribution to DDC::Concordance for CPAN-compatibility
	+ restructured directory (DDC/ -> lib/DDC/) to avoid confusing ExtUtils::MakeMaker

	+ moved top-level module from 'DDC' to 'DDC::Concordance'
	+ kept dummy top-level wrapper DDC.pm for backwards-compatibility
	+ workaround for name conflict with Torsten Raudssus' "DDC" in the
	  "Data-Coloured" distribution ( https://metacpan.org/pod/DDC )
	  (see RT bug #107031, https://rt.cpan.org/Public/Bug/Display.html?id=107031)

v0.16 Fri, 24 Apr 2015 14:13:09 +0200 moocow

	+ improved query benchmarking, allow reading query-list from a file

v0.12 Fri, 27 Jun 2014 12:17:19 +0200 moocow

	+ added Changes

2014-05-14  moocow

	  DDC::Client::Distributed::queryJson

2014-05-07  moocow
	* [r227] ddc-cgi.perl: + more request-mode stuff for ddc-cgi.perl

2014-03-27  moocow
	* [r159] DDC.pm, DDC/Query.pm, DDC/Query/yylexer.pm,
	  DDC/Query/yyparser.output, DDC/Query/yyparser.pm,
	  DDC/Query/yyparser.yp: + updated DDC-perl query lexer+parser for
	  ddc-v2.0.21
	  - TODO: chuck the pure-perl implementation and use the C++ parser
	  directly somehow

2014-03-07  moocow
	* [r121] DDC/Format/Kwic.pm: + kwic formatter: output total number
	  of hits

2014-03-03  moocow
	* [r112] ddc-query.perl: + parse port in ddc-query.perl (for less
	  confusing error messages on failure)#

2014-02-24  moocow
	* [r111] ddc-query.perl: + ddc-query.perl: append newline to
	  raw-data results if not already present
	* [r106] DDC.pm: + load kwic format by default
	* [r105] ddc-query.perl: + removed debugging code
	* [r104] DDC.pm, DDC/Format/Kwic.pm, ddc-query.perl: + v0.09: added
	  Kwic format

2014-02-19  moocow
	* [r101] ddc-query.perl: + ddc-query.perl: bench raw queries, not
	  parsing

2014-02-18  moocow
	* [r99] DDC/Client.pm, DDC/Client/Distributed.pm, ddc-query.perl: +
	  ddc-query.perl: added -request option: alias for -raw
	  -mode=request (formerly -mode=raw)

2014-02-17  moocow
	* [r96] DDC/Client.pm, DDC/Client/Distributed.pm, ddc-query.perl: +
	  v0.08: added -mode=raw queries to test and verify ddc_proto
	  manpage

2014-01-08  moocow
	* [r86] DDC.pm: + updated to v0.08
	* [r85] ., DDC/Format/JSON.pm: + added JSON formatter abs(level)>1
	  check for canonical-json

2012-01-17  moocow
	* [r26] README.txt: + typo fix
	* [r25] ., DDC.pm, DDC/Client.pm, DDC/Client/Distributed.pm,
	  DDC/Filter.pm, DDC/Format.pm, DDC/Format/Dumper.pm,
	  DDC/Format/JSON.pm, DDC/Format/Raw.pm, DDC/Format/Template.pm,

	  DDC/Query/yyparser.output, DDC/Query/yyparser.pm,
	  DDC/Query/yyparser.yp, DDC/Utils.pm, README.rpod, qparse.perl:
	  v0.07: got DDC::Query::Parser up and running again
	  - this is a real PITA to maintain parallel to the 'real' DDC
	  query parser in C++
	  - eventually, there should be an XS perl module which just calls
	  the real parser

2011-12-02  moocow
	* [r21] DDC/Client.pm: + better error handling on client reads
	* [r20] DDC/Client.pm: + fixed typo in error message
