software naming/release cycle for native IOS

[d-fillmore]

Can anyone explain the software release cycle for native IOS to me?

eg - what's the difference between 12.2(18)SX1 & SX6 - is it just bug fixes?

what's the difference between SXE and SXF?

Why does it never reach GD?

Cheers, Dom

Last sentence from this document:

A number appended to the X release (for example, Cisco IOS Software Release 12.0(2)XC1), indicates a rebuild of that release (in this case Cisco IOS Software Release 12.0(2)XC) caused by a catastrophic defect
