I made a test file and can see what you mean. I'm having our developer take a look. I'll let you know when I find out more.
As most of us are using in5 as "export to html plugin", that means also to export "InDesign text" as "html text". ...otherwise we can use any image/svg exporting tool and present html pages as "svg" or "images".
Meanwhile, here is an example screenshoot from indesign:
Justin just posted 3.7.9 that includes the fix.
Dear in5 team,
What to say... you are amazing!
While I was thinking, how to prepare my team to dal with missing "soft returns" and most of all, to prepare client to excuse us if we miss something during manual adjustments...
The update came just in time and can confirm, paragraph text "soft returns - <br>" is back.
Many thanks for prompt response!
...suppose also from many developers using in5 as InDesign magic touch.
Thank you for the kind words. The team definitely worked at record speed.
