.IX Header "MANUAL"
.SS "Type::Tiny Stability Policy"
.IX Subsection "Type::Tiny Stability Policy"
Type::Tiny 1.000000+ is considered stable. Any changes to the API that
are big enough to \fIrequire\fR changes to the test suite will be preceded
by a \fIsix month\fR notice period, with the following exceptions:
.IP \(bu 4
Any changes which are necessary to maintain compatibility with new
releases of Moose, Moo, and other software that Type::Tiny needs
to integrate with.
.IP \(bu 4
Changes to maintain compatibility with future versions of Perl itself.
.IP \(bu 4
Where a change fixes a contradiction between the implementation and
documentation of Type::Tiny.
.IP \(bu 4
Where a feature is explicitly documented as being "experimental" or
"unstable".
.IP \(bu 4
Improvements to the text of error messages.
.SS "Experimental and Unstable Type::Tiny Features"
.IX Subsection "Experimental and Unstable Type::Tiny Features"
The following list is currently non-exhaustive.
.IP \(bu 4
The following type checks result may vary based on your version of
Perl and whether Type::Tiny::XS is installed. Their outcome is currently
considered undefined, and may change in future versions.
.RS 4
.IP \(bu 4
Using \fBObject\fR and similar type checks on unblessed regular expression
references, the outcome is undefined.
.IP \(bu 4
On all current versions of Perl, false (\f(CW\*(C`!!0\*(C'\fR) stringifies to the
empty string (but using Devel::Peek you can tell the difference between
this value and a normal empty string), so \fBInt\fR and subtypes of \fBInt\fR
do not consider it to be an integer. If Perl's behaviour ever changes,
you might not be able to rely on this outcome. True (\f(CW\*(C`!!1\*(C'\fR)
stringifies as "1", so is considered an integer.
.IP \(bu 4
A glob (not a globref but an actual glob) currently passes the
\&\fBStringLike\fR type constraint but not the \fBStr\fR type constraint.
.IP \(bu 4
The  \fBBoolLike\fR type is intended to extend \fBBool\fR to cover overloaded
boolean objects, but the exact mechanism it uses may change.
.RE
.RS 4
.RE
.IP \(bu 4
Type::Tiny's \f(CW\*(C`my_methods\*(C'\fR attribute and the functionality it
provides is experimental.
.IP \(bu 4
The parameterizable coercion API is subject to change.
.IP \(bu 4
The interaction of deep coercions and mutable coercions currently results
in ill-defined behaviour. This could change at any time.
.IP \(bu 4
Type::Registry's ability to import MooseX::Types and MouseX::Types
type libraries is experimental.
.IP \(bu 4
These modules are considered part of Type::Tiny's internals, and not
covered by the stability policy:
Devel::TypeTiny::Perl58Compat,
Type::Coercion::FromMoose,
Type::Params::Alternatives,
Type::Params::Parameter,
Type::Params::Signature,
Type::Tiny::_HalfOp,
Types::Standard::ArrayRef,
Types::Standard::CycleTuple,
Types::Standard::Dict,
Types::Standard::HashRef,
Types::Standard::Map,
Types::Standard::ScalarRef,
Types::Standard::StrMatch,
Types::Standard::Tied, and
Types::Standard::Tuple.
.IP \(bu 4
Reply::Plugin::TypeTiny is not covered by the stability policy.
.SS "Type::Tiny Versioning Policy"
.IX Subsection "Type::Tiny Versioning Policy"
As of 1.000000, this distribution follows a versioning scheme similar
to Moo, which is based on a semver <http://semver.org/>\-like three
component version number, but with the last two components each
represented by three decimal digits in the fractional part of the
version number. That is, version 1.003002 of the software represents
"1.3.2".
.PP
Additionally, releases where the second component is an odd number will
be considered unstable/trial releases. (These will also include an
underscore in the version number as per the usual CPAN convention.)
.SS "Perl Version Support"
.IX Subsection "Perl Version Support"
Type::Tiny 0.000_01 to Type::Tiny 0.015_04 required Perl 5.8.1.
.PP
Type::Tiny 0.015_05+ and Type::Tiny 1.000000+ requires Perl 5.6.1.
.PP
Type::Tiny 2.000000+ will require Perl 5.8.1.
