=head1 MANUAL

=head2 Type::Tiny Stability Policy

Type::Tiny 1.000000 is considered stable. Any changes to the API that
are big enough to I<require> changes to the test suite will be preceded
by a I<< six month >> notice period, with the following exceptions:

=over

=item *

Any changes which are necessary to maintain compatibility with new
releases of L<Moose>, L<Moo>, and other software that Type::Tiny needs
to integrate with.

=item *

Changes to maintain compatibility with future versions of Perl itself.

=item *

Where a change fixes a contradiction between the implementation and
documentation of Type::Tiny.

=item *

Where a feature is explicitly documented as being "experimental" or
"unstable".

=item *

Improvements to the text of error messages.

=head2 Experimental and Unstable Type::Tiny Features

The following list is currently non-exhaustive.

=over

=item *

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.

=over

=item *

Using B<Object> and similar type checks on unblessed regular expression
references, the outcome is undefined.

=item *

On all current versions of Perl, false (C<< !!0 >>) stringifies to the
empty string (but using Devel::Peek you can tell the difference between
this value and a normal empty string), so B<Int> and subtypes of B<Int>
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 (C<< !!1 >>)
stringifies as "1", so is considered an integer.

=item *

A glob (not a globref but an actual glob) currently passes the
B<StringLike> type constraint but not the B<Str> type constraint.

=back

=item *

L<Type::Tiny>'s C<my_methods> attribute and the functionality it
provides is experimental.

=item *

The L<parameterizable coercion API|Type::Coercion> is subject to change.

=item *

The interaction of deep coercions and mutable coercions currently results
in ill-defined behaviour. This could change at any time.

=item *

L<Type::Registry>'s ability to import L<MooseX::Types> and L<MouseX::Types>
type libraries is experimental.

=item *

These modules are considered part of Type::Tiny's internals, and not
covered by the stability policy:
L<Devel::TypeTiny::Perl56Compat>,
L<Devel::TypeTiny::Perl58Compat>,
L<Type::Coercion::FromMoose>,
L<Type::Tiny::_HalfOp>,
L<Types::Standard::ArrayRef>,
L<Types::Standard::CycleTuple>,
L<Types::Standard::Dict>,
L<Types::Standard::HashRef>,
L<Types::Standard::Map>,
L<Types::Standard::ScalarRef>,
L<Types::Standard::StrMatch>,
L<Types::Standard::Tied>, and
L<Types::Standard::Tuple>.

=item *

L<Reply::Plugin::TypeTiny> is not covered by the stability policy.

=back

=head2 Type::Tiny Versioning Policy

As of 1.000000, this distribution follows a versioning scheme similar
to L<Moo>, which is based on a L<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".

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.)
