No need for the red face. It's not necessarily obvious that version 
numbers are not really decimal numbers. With decimal numbers, 1.1 is 
equivalent to 1.10 but not so with version numbers. Likewise if we look 
at 1.1, 1.11, 1.12, 1.2, with version numbers these are sorted 1.1, 1.2, 
1.11, 1.12 rather than in their numerical order. The trick is to read 
1.13 as one-point-thirteen rather than one-point-one-three and treat the 
decimal place as a separator, not a decimal point. I suppose if we 
always knew there would be less than 100 sub-version numbers, we could 
start with 1.01 and work towards 1.99 and it would make more sense. This 
seems to be more and more universal across software projects.
