There is MNG-5935 which is fixed and has an impact on the optional flag in dependency management. See this commit and its message. <https://git-wip-us.apache.org/repos/asf?p=maven.git;a=commit;h=184f58ff83a6d043c695a07f1b1ae89630f6bc9e> and there is MNG-5227 which has an impact on the optional flag in dependency management. See this commit and its message. <https://git-wip-us.apache.org/repos/asf?p=maven.git;a=commit;h=09bfdee699443b2482d2427b5eff7226768b340a>. Someone on dev@ has reported that he is using the optional flag in dependency management (setting it to true) and that he has noticed that this starts working in 3.4-SNAPSHOT for him. I haven't asked if he noticed it is not working before. What is important to know is that before the fix for MNG-5935 all managed dependencies were implicitly managing optional to false. Aether got updated to change the optional flag from 'boolean' to 'Boolean' and Maven has not been updated to reflect that. So instead of passing 'null' to Aether, it passed 'false' meaning 'manage the optional flag to false' where it should have passed 'null' meaning 'do not manage the optional flag in any way'.
