The change in spindle pin names was between 2.7 and 2.8. 2.8.0 to 2.81
was a minor bugfix update.

Lots of other things changed between 2.7 and 2.8. About 10 years worth
of background work was finally merged.

And, it is documented:
http://linuxcnc.org/docs/2.8/html/getting-started/updating-linuxcnc.html#_updating_configuration_files_for_2_8_x

The full extent of the pin renaming can be learned by looking at the
auto-translation script.

But, in general, you you don't need to know as long as you read the
correct docs for the version you are running.

Don't use LinuxCNC docs if you want to know about Machinekit, use the
Machinekit docs.

And, for LinuxCNC docs, look here: http://www.linuxcnc.org/documents/
And choose the version that you want to know about.
