[font='Open Sans', 'segoe ui', 'Helvetica Neue', Helvetica, Arial, sans-serif]There used to be “latest ” in the old days - even as late as the 2008 rebrand. It seemed to fall out of favour, leading to everything branded as “Breaking”.[/font]

If my ruined memory serves, I think there were two early variants of 'latest'-type straps: 'News Update'; and 'Latest Pictures'. I'm sure I remember 'News Update' being used during the time of the red-and-ivory-era purple astons/lower-thirds on News 24, as well during the SUPER-CHONKY red-and-black generation (the ones that used the hideous Gill Sans Ultra Bold font - 2002ish?). I believe that was also around the time that 'Latest Pictures' straps started to appear on both channels. 

Both variants continued to be used sporadically through to the 2008 rebrand after which, as you rightly say, all updates to rolling news stories came to be known simply as 'Breaking'. 

As far as I recall, I don't think 'Latest' (on its own) was used on any previous generation of News (24)/World lower-thirds. However, my memory is largely made of dust, so it's quite possible that I'm completely wrong about everything I've just said.
