Details of what was updated and added for newer components VS obsolete

When you open a filter and you see that any of the components may have a number after the name of that component, this means that this component is obsolete and not the latest one, because the latests ones does not have any number after name.

So, then if this component with number is obsolete, it means that the latest newest version of that same component has something new or updated versus the obsolete one

What I want to know if there is somewhere specified the differences and what was updated on each obsolete component so when creating a filter you can decide what component to use and if it would be interesting, convenient or needed to use the latest version or not, and could be used the obsolete one instead.

I ask it because there are many old filters that can be used a part of it, but it may have obsolete components, and as it is not easy at all sometimes to replace a component with another as you have to relink again all the connections, so if you could know if it would be really worth the time and work to update it you could do it, but is needed to know what was changed, modified or added.

For example I have seen in the FF Help Bomber Plus 6003 and Bomber Plus seems to be very similar and I have only found until now that

Bomber Plus 6003 - Particle Order and Layer Order are GREY nodes

Bomber Plus - Particle Order and Layer Order are GREEN nodes
I can not know if there could be any new node as the list is very long

Thanks very much for any possible help
