    Clarify POD for prohibit_returned_lexicals to make clear (I hope)
    that it applies to 'state' varables as well as 'my' variables, but
    does NOT detect or handle implicit returns.

    allow_state_in_expression now accepts post-increment and -decrement.
    Thanks to Olaf Alders for finding this.

    Correct generation of 'provides' metadata. Thanks to Favio Poletti
    for blogging
    https://github.polettix.it/ETOOBUSY/2021/06/15/the-real-pause-workaround/,
    and ultimately to Joel Berger for the pointer to
    https://metacpan.org/pod/CPAN::Meta::Spec#no_index

    Optionally check variable in catch(). This is controlled by the
    check_catch configuration item, which is off by default.

    Dig out variables declared inside strings e.g. "foo@{[ my $bar ]}"

    Find variables declared in passing.  That is, things like
    Readonly::Scalar my $answer => 42; which do not get parsed by PPI as
    a PPI::Statement::Variable.

    Pick up $y in '( my $x, my $y )'. The previous code picked up only
    the variables declared before the first comma in the
    PPI::Statement::Variable.

    Refactor handling of derived PPI documents.

    Refactor the recording of symbol declarations and uses.

    examples/unused-vars is now driven by options on the command line,
    not by a configuration file.

    No longer recommend Readonly::XS. Thanks to Jay Kahrman for pointing
    out that this was no longer appropriate.

    Add Boolean configuration item allow_state_in_expression, which
    allows an otherwise-unused state variable if the policy thinks the
    computed value is also used in an expression. This item is false by
    default.

    Fix for() list and my():

    The iterator variable (if any) for a for() or foreach() is not
    in-scope as seen from the list. This is an issue for code like
    for my $x ( @{ $x } ) {...}

    The variable specified by my() is not in-scope as seen from the
    right-hand side of an assignment (if any). This is an issue for
    my $x = $x

    Thanks to Heinz Knutzen for finding these.

    Remove 'mailto' bugtracker metadata Its presence appears to tell RT

  Refactor the logic that discovers which variables are interpolated
    into double-quotish strings into PPIx::QuoteLike. This does not
    include regular expressions, which are already handled by
    PPIx::Regexp.

  Survive variable declarations that declare nothing. These can appear
    if (e.g.) PPI mis-parses an attribute list, and that attribute list
    contains something like 'Arg(state)'.

  Allow 'return ( my $x = 0 )'

    This construction can be used to return a temporary value from an lvalue
    subroutine. The case 'return my $x = 0' is equivalent, but was not
    recognized as defining a variable. Now both are recognized and accepted
    by default.

    If you want to reject these, there is a new Boolean configuration item,
    prohibit_returned_lexicals.
