version 0.013; 2010-11-16

• bugfix: avoid triggering a core assertion on debugging builds, by using OP_NULL as a stalking-horse opcode instead of OP_PUSHMARK (nothing actually broke apart from the assertion)
• provide reserve definition of Newx(), to allow compilation on non-threaded Perls prior to 5.8.8
• avoid a compiler warning from the reserve implementation of the ptr_table data structure

version 0.012; 2010-11-03

• generate custom ops for most functions, to avoid heavyweight function calls at runtime
• change "please update me" messages to "please update Params::Classify" for clarity
• use shared SVs for return values from scalar_class() and ref_type()
• allow is_able() and check_able() to be called with only one argument
• change message generated by check_strictly_blessed() when called with only one argument, to be consistent between XS and pure Perl
• refactor some Perl version portability code
• in XS, declare "PROTOTYPES: DISABLE" to prevent automatic generation of unintended prototypes
• jump through hoops to avoid compiler warnings
• in t/setup_pp.pl, avoid a warning that occurs if XSLoader::load() is given no arguments, which is now a valid usage

version 0.011; 2010-08-21

• bugfix: add a typemap entry for "const char *", to make XS version of scalar_class() work correctly on Perl 5.6, having been broken by the const fix in version 0.010
• in XS code, on Perls where it exists (prior to 5.9.5), treat SVt_PVBM as a scalar referent type

version 0.010; 2010-08-20

• in XS, use PERL_NO_GET_CONTEXT for efficiency
• use full stricture in test suite
• also test POD coverage of pure Perl implementation
• in test suite, make all numeric comparisons against $] stringify it first, to avoid architecture-dependent problems with floating point rounding giving it an unexpected numeric value
• make XS code const clean for gcc -Wwrite-strings
• in Build.PL, explicitly set needs_compiler to avoid bogus auto-dependency on ExtUtils::CBuilder
• in Build.PL, explicitly declare configure-time requirements
• add MYMETA.yml to .cvsignore

version 0.009; 2009-10-07

• port to Perl 5.11.0, supporting the addition of first-class regexp objects (which are actually a type of scalar) and the removal of the distinct RV type; new functions is_regexp() and check_regexp()
• fix a test skip count in t/ref.t, which was causing false test failures on Perl 5.6
• check for required Perl version at runtime

version 0.008; 2009-09-10

• add "check_" functions for argument checking
• strict argument checking in all functions that take control arguments
• revise documentation
• revise pure Perl code to avoid unnecessary argument copying
• in XS code, make all auxiliary functions "static"
• revise POD markup
• remove bogus "exit 0" from Build.PL

version 0.007; 2009-05-13

• XS implementation, used if available with fallback to existing pure Perl implementation if XS is not available
• use simpler "parent" pragma in place of "base"
• in documentation, use the term "truth value" instead of the less precise "boolean"
• use full stricture in Build.PL

version 0.006; 2009-02-15

• withdraw is_pure_string() and is_pure_number() functions, because they've never worked right and bring in a big dependency for marginal utility
• use "base" pragma to import Exporter behaviour
• test POD syntax and coverage
• build with Module::Build instead of ExtUtils::MakeMaker
• complete dependency list
• include signature in distribution
• in documentation, separate "license" section from "copyright" section

version 0.005; 2007-09-02

• in t/purity.t, modify purity test on dualvar(0, "0") to operate appropriately on older Perls where this has a different numeric value from 0
• in t/purity.t, fix a skip count for the case where dualvar() is not available

version 0.004; 2007-08-16

• in t/purity.t, fix a skip count for the case where floating point zero is unsigned

version 0.003; 2007-08-15

• in t/purity.t, modify purity test on dualvar(+0.0, "0") to operate appropriately on older Perls where "0" numifies to a floating point zero, and add a test for dualvar(0, "0")

version 0.002; 2007-01-25

• add is_pure_string() and is_pure_number() functions that determine how complicated a string scalar is
• in documentation for is_number(), reference Scalar::Number and Data::Integer
• correct version requirement of Scalar::Util in module, making it consistent with the dependency listed in Makefile.PL

version 0.001; 2006-08-03

• bugfix: in is_number(), check whether numeric conversion warns, rather than using looks_like_number(), to avoid being confused by dualvars
• in t/ref.t, skip *foo{FORMAT} tests on older Perls that don't provide that facility
• refer to Data::Float for classification of floating point values
• versioned dependencies in .pm
• declare module dependencies in Makefile.PL
• correct .cvsignore (had copy&modify detritus)
• include Changes file

version 0.000; 2004-03-20

• initial released version
