      - Fixed PREREQ_PM, adding Hash::NoRef to it.


0.12  9 Apr 2004
      - Added wrapper for caller() to handle rigth the package names.


0.11  5 Feb 2004
      - New trace system for global variables of compartments linkeds to others and
        for complex cache systems.


0.10  23 Jan 2004
      - Safe::Hole is back as a dependences. Safe::Hole 0.10+ works well.
      - Bug fixes for global variables of cache compartments and persistent code.


0.09  16 Jan 2004
      - Fixed bug with select() overwrited, for slection of handlers from a package
        (forgot to keep the caller base).
      - Added Safe::World::Hole, to keep compatiblity, since Safe::World/0.09 breaks *INC behavior for Safe::World.
      - Removed dependency of Safe::Hole
      - Added wrapper for UNIVERSAL::isa() to handle rigth the package names.


0.08  29 Dec 2003
      - Added method reset_internals().
      - Added method stdout_buffer_data().
      - Fixed %INC access for link_workd() and unlink_world().
      - Added unshare_vars() call on DESTROY().
      - Added method use_shared().
      - Fixed bug on reuse of cached package and compiled references to *_, specialy @_.
      - Fixed behavior of $^R, that is a global variable that can't be shared, since doesn't exists at $main::^R,
        and have his SCALAR reference change during the RE. ($^R is used by REGEXP, see perlvar POD).
      - Added method eval_no_warn(), to run codes and do not have any alert, error, die, or warn.
      - Fixed bug with select(), that happens due the different behaviors of select() with STDOUT inside compartments
        on Perl-5.6x and Perl-5.8x. (Bug found with mod_perl2).


0.07  21 Dec 2003
      - Added cache of scopes at Safe::World::Scope.
      - Blocked access to the symbols tables through Safe::World::Scope objects.
      - Fixed bug on unlink_world(), where the call to unlink_package() was wrong.
      - Removed select() of previous output on print_stderr(), due problems when called from internal erros,
        like use on inexistent modules. But the select() of previous output on print_stdout() is kept to avoid self loops!


0.06  19 Dec 2003
      - Added method op_deny, op_deny_only, op_permit, op_permit_only.
      - Fixed minor bug on eval(), when called from inside.
      - Fixed DESTROY for HOOK of Safe::World::Scope.
      - Added some internal select_static() calls for optimization.
      - Fixed autohead for print_header().


0.05  16 Dec 2003
      - Added method op_deny, op_deny_only, op_permit, op_permit_only.
      - Added methods reset_output(), unlink_all_worlds().
      - Fixed bug on destroy.
      - Fixed minor bug on eval(), when called from inside.
      - New module Safe::World::Scope, for objects that works inside the World without share packages.
      - Added dependece to Safe::Hole/0.08, due Safe::World::Scope.
      - All the Safe::World* packages reviseds to use Safe::World::Scope access.


0.04  09 Dec 2003
      - New test with IO::Socket to test select() inside the compartment.
        (Due old problems in other works with Safe and mod_perl, just to ensure that it's ok in Safe::World).
      - Fixed warnings for constant redefinition on Perl-5.8.x when cleanning the compartment.
      - Added method redirect_stdout() and restore_stdout().
      - Fixed bug for internal call of die(). Now die() doesn't exit from the World, only from it's own eval().
        What enables other eval() calls to the World.
      - Fixed bug with ignored warnings, like syntax error.
      - Added method eval_args() and eval_pack_args().


0.03  30 Nov 2003
      - No more dependence of Safe. Own implementation of Safe at Safe::World::Compartment,

      - Fixed some minor bug in the headers handler for HEADOUT.
      - Added method reset().
      - Added methods close_tiestdout() and close_tiestderr().
