Source: boost1.81 Version 1.81.0-1 Severity: serious Hi Maintainer
boost1.81's autopkgtests depend on packages from boost-defaults, so the autopkgtests are actually run against boost1.74. The autopkgtests used to have versioned dependencies, but that was changed [1] some time ago. Regards Graham [1] https://salsa.debian.org/debian/boost/-/commit/0bf0df0680f9255771424b7b0cd1aa040d847cdd
