Revision history for Signals-XSIG

1.00	2022-05-30
        Major rewrite of internals
        - low-level Signals::XSIG reference type
        - all %SIG, %XSIG interactions manipulate Signals::XSIG::Meta objects
        - removed need to untie-retie %SIG
        - local %SIG  now causes fewer problems
        unimport/import can disable/re-enable the module
