Revision history for Perl extension DBIx::DataModel.

v1.19 17.08.2009
  - insert(..) now accepts a list of arrayrefs (kind of 'populate' method)
  - fixes in the doc (thanks to Terrence Brannon for many suggestions)
  - announce discussion group @ googlegroups & public source @ svn.ali.as
  
v1.18 31.07.2009
  - added missing "use DBI" in Schema::Generator
  - added Schema methods 'table' and 'view'
  - more liberal in _createPackage, just check not clobbering @ISA

v1.17 10.06.2009
  - treat case when $schema->dbh is undef

v1.16 10.06.2009
  - doTransaction properly calls dbh() instead of direct access to classData
  - localizeState properly calls setter methods when restoring previous state

v1.15 02.06.2009
  - bug fix on reporting rollback exceptions

v1.14 20.04.2009
  - bug fix on adaptations for SQL::Abstract v1.51 (select(-where => [...]))

v1.13 08.04.2009
  - adaptations for SQL::Abstract v1.51 (syntax change for -and/-or)

v1.12 17.03.2009
  - stupid error in count of SKIP tests (MsAccess.t) when DBD::Mock is absent

v1.11
  - dependency on SQL::Abstract v1.50, tests adapted
  - nested records in insert(): allow for empty arrayref

v1.10
  - exceptions during doTransaction are returned as a blessed arrayref

v1.09
  - fixed bug with ->fetch(@prim_key) when scalar(@prim_key) > 1

v1.08
  - fixed bug with -pageIndex (missing code)

v1.07
   - adapted tests for DBD::Mock 1.39

v1.06
  - Schema.pm : replaced deprecated 
        if(defined(%{$pck.".."})) 
    by 
        if(%{$pck.".."})
  - t/Storable.t : 
      - parent process in eval() to avoid child zombie if parent dies
      - if Perl < 5.8, fallback to IO::String
  - t/DBIx-DataModel.t : 
      - pre-test DBD::Mock on functionality rather than version number
  - Schema.pm, View.pm : dynamic subclasses created through
       @{$subclass."::ISA"} = @$aref;
    instead of 
       *{$subclass."::ISA"} = $aref;
    so that Perl5.10 method cache is properly invalidated.
