With regards to the picture, this is the closest I could get:


sequenceDiagram
    participant 8
#    participant 9
#    participant 10
    participant 11
 #   participant 12
 #   participant 13
 #   participant 14
 #   participant 15
 #   participant 16
    participant 17
 #   participant 18
 #   participant 19
 #   participant 20
    participant 21
 #   participant 22
    participant tbd
    activate 8
    activate 11
    activate 17
    activate 21
    8->tbd: Issue relevant to 8 and all future releases
    Note left of 8: Affects version: 8
    8->tbd: No need to add additional releases as they are implied
    Note left of 8: Affects version: 8, 8u40, 9, 12
    11->tbd: Adding the occasional LTS release value is ok
    Note left of 8: Affects version: 11, 21
    8->>11: Use N-na to indicate that the issue is no longer relevant from that release
    Note left of 8: Label: 12-na
    8-x11: Use N-wnf to indicate that a fix will not be backported to that release
    Note left of 8: Label: 11-wnf
    deactivate 8
    deactivate 11
    deactivate 17
    deactivate 21


I commented out the non-lts participants here since the font got too small with all of them in the picture. Not sure how that will look on a generated version. It's possible to change the CSS for the chart.
