Difference between 1.3 and 1.5 descr_sm_factions.txt?

[Kaidonni]

I'm running 1.3, and because of a reinstallation of Windows, it doesn't recognise BI or RTW when I try to patch to 1.5/1.6, so RTW needs reinstalling.

However, it has hit me that I might not need to reinstall and patch up just yet...How does the descr_sm_factions.txt differ between 1.3 and 1.5? Notably, the prefers_naval_invasions line? Does it say yes instead of no for some factions? I ask because this concerns the Roman expansion bug. This might help me instead of having to reinstall right away. Thanks for any help you can afford me.

EDIT: Currently, I have the Scipii, Brutii, Britannia and Carthage set to yes on prefers_naval_invasions. I just don't know if it will really make any difference though. That's why I'm asking on the differences between the two versions of the same file. Any help on which factions have it set to yes in 1.5 would also be appreciated. In my Pontus 1.3 H/H campaign, it's 265BC Winter, but I don't want to start over...a quick alteration to the descr_sm_factions.txt could very well be easier rather than reinstalling, patching, etc etc. Plus I just don't want to start over, so any changes to make my current campaign better before it's far too late will be great. Thanks.
