Points self updates at this organisation, following the move from bmx269/affinity-guard.
The release source is compiled into the plugin rather than configured, so an install left on 1.0.0 will stop updating itself once a repository of the old name exists again — a fork recreates that name, and forks do not inherit releases. Copy affinity-guard.php from this release over any 1.0.0 install rather than waiting for it to update on its own.
No behaviour, constants or hooks changed. See CHANGELOG.md.
