A stupid newbie question, but I have been curious about this for a while. What constitutes a project upgrading from say a 2.3.1 to 2.3.2 instead of 2.3.1 to 2.4.1? Is the last decimal just some slight debugging or what? And how many changes would have to be made for it to go from something like a 2.4.1 to version 3 instead of 2.5.1 or 2.4.2? A complete overhaul? Hopefully that made sense. I know this sounds like a stupid question, but I'm sure I'm not the only newbie out there who's unsure about this. Thanks in advance.
