What about the new release numbering scheme?

Maintenance releases, patch releases and double-dot releases (e.g., 5.2.1) are now all named with the "M" label such as 5.2 M010 (which would be pronounced "five point two em ten" or "em ten" for short). You install these releases on top of the F000 release (the initial release) or any M release that came out afterwards.

Regularly-scheduled (every 2 months) maintenance releases are incremented by 10, so our product calendar lists M010, M020, M030, etc. Maintenance releases always include bug fixes and sometimes add new features.

If special-purpose maintenance releases are required, we'll use the numbers in between. For example, there's an M011 patch release in the works that's targeted specifically to customers planning to install the 1.2 release of our SPL application.
