The questions to ask are:

Does the upgrade require intervention? ie, if someone did the upgrade
would they have to manually change config files, or migrate databases
or whatever?

No, the 2.3 version just adds some features and there wouldn't be any needed changes to config files or databases to support the update.
Next, is the package a gui one that changes look and feel? ie, would
some user who updated suddenly have to relearn where the various
options are?

There's no GUI or user facing part of it, so it would be effect developers but not users.
Finally, does it change abi/api any? If it was updated would people
have to rebuild other things to work with it?

There were additions to the API to support the new features and I'm guessing that there may be ABI changes as well. Basically, I'm guessing that a rebuild would be necessary.
