Assim que os números de versão Maior (aqui é 229 ) e Menor (aqui é 4 ) não mudam, você pode instalar a atualização sem pensando no bug. O número da versão Manutenção (aqui é 19 ) inclui apenas correções de bugs.
Além disso, suponho que o que você está procurando é Changelog . Ele mostrará quais alterações são aplicadas em diferentes versões. A saída de apt changelog systemd :
systemd (229-4ubuntu19) xenial; urgency=medium
* debian/extra/units/systemd-resolved.service.d/resolvconf.conf: partially
revert, by removing ExecStart|StopPost lines, as these are not needed on
xenial and generate warnings in the journal. (LP: #1704677)
