Just curious, what consitutes a 'letter' verses a 'number' upgrade?

I.e. Why 8a...b...c...? Rather than 8...9...10...etc.

I just increment the letter. Sometimes Hugo says - "We've added lots of user-visible stuff so why don't you call it betaN instead" and I do...

I think it just depends on how important the user visible changes are. We've made major behind the scenes improvements for the next release so it will be 8c (at least I hope so - I've already built parts of it and I don't want to rebuild them).
