=head1 DESCRIPTION

Tired of having to update your F<Changes> file by hand with the new
version and release date / time each time you release your distribution?
Well, this plugin is for you.

Add this plugin to your F<dist.ini>, and the following to your
F<Changes> file:

  {{$NEXT}}

The C<NextRelease> plugin will then do 2 things:

=over 4

=item * At build time, this special marker will be replaced with the
version and the build date, to form a standard changelog header. This
will be done to the in-memory file - the original F<Changes> file won't
be updated.

=item * After release (when running C<dzil release>), since the version
and build date are now part of your dist's history, the real F<Changes>
file (not the in-memory one) will be updated with this piece of
information.

=back

The module accepts the following options in its F<dist.ini> section:

=over 4

=item filename

the name of your changelog file;  defaults to F<Changes>

=item update_filename

the file to which to write an updated changelog to; defaults to the C<filename>

=item format

sprintf-like string used to compute the next value of C<{{$NEXT}}>;
defaults to C<%-9v %{yyyy-MM-dd HH:mm:ssZZZZZ VVVV}d%{ (TRIAL RELEASE)}T>

=item time_zone

the timezone to use when generating the date;  defaults to I<local>

=item user_stash

the name of the stash where the user's name and email address can be found;
defaults to C<%User>

=back

The module allows the following sprintf-like format codes in the C<format>:

=over 4

=item C<%v>

The distribution version

=item C<%{-TRIAL}T>

Expands to -TRIAL (or any other supplied string) if this
is a trial release, or the empty string if not.  A bare C<%T> means
C<%{-TRIAL}T>.

=item C<%{-TRIAL}V>

Equivalent to C<%v%{-TRIAL}T>, to allow for the application of modifiers such
as space padding to the entire version string produced.

=item C<%{CLDR format}d>

The date of the release.  You can use any CLDR format supported by
L<DateTime>.  You must specify the format; there is no default.

=item C<%U>

The name of the user making this release (from C<user_stash>).

=item C<%E>

The email address of the user making this release (from C<user_stash>).

=item C<%P>

The CPAN (PAUSE) id of the user making this release (from -Releaser plugins;
see L<[UploadToCPAN]|Dist::Zilla::Plugin::UploadToCPAN/username>).

=item C<%n>

A newline

=item C<%t>

A tab

=head1 PERL VERSION

This module should work on any version of perl still receiving updates from
the Perl 5 Porters.  This means it should work on any version of perl released
in the last two to three years.  (That is, if the most recently released
version is v5.40, then this module should work on both v5.40 and v5.38.)

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.
