/**
 * The installed software version, single source of truth.
 *
 * It is written here by scripts/create-release-zip.sh when a release package is
 * built, and changes on an installation as a side effect of an update copying
 * this file over. Nothing writes it at runtime.
 *
 * The manage client reads the literal below with a regular expression rather
 * than by loading the file (see manage-client/config.php), so the value stays
 * readable even in a request that already defined the constant.
