A while back someone kindly created a list of plugins that were included in Sonar 8 to X3.

I've hunted up a few other lists and we can now list plugins going back to Sonar 3. I suspect a few are missing or may be incorrect so if you let me know I'll up date the spreadsheet.

Check out my signature and look for "Sonar_Plugins_3 to X3.xslx"

In the spreadsheet, select row 3 and apply "Freeze Panes". This will make the first two rows (i.e. the column headers) remain visible when scrolling.
 

Additional info:
Dimension LE and Dropzone were included with Sonar 7.
SpectreFX, PSYNII, RXP, Dreamstation and SFZ were included with Sonar 6 & 7.
Cyclone was included with Sonar 5 (and maybe earlier versions too).

Thanks Kev. Man there's lots of Aussies on this forum esp Victorians.
I created the spreadsheet on my iPad so I don't know if I can Freeze Panes but will check and add if possible. Others created the lists in various posts from which I got the info. I didn't do much more than copy it into a spreadsheet to manage the data.

Also:
The Sonitus fx plugin set was certainly included in versions 6 and 7.
So was TTS-1.
But I have no idea when these were first introduced.

I've got Panes displaying so make sure you scroll to the right and top.

I've got th showing in Sonar 3 but didn't fill in the gap to 6 and 7
