V2017 uses the IPC-7351C proposed solder joint goals.

V2016 uses the IPC-7351B solder joint goals.

You can compare them in the Excel spreadsheets located in this folder -
C:\Program Files (x86)\PCB Libraries\Library Expert 2017\Documents
  • IPC-7351C (Proposed) Solder Joint Goal Tables v1.4
  • IPC-7351B Solder Joint Goal Tables v1.4
However, using V2017 you can reset the solder joint goals back to IPC-7351B by opening the Preference file -
IPC-7351B_DefaultPreferences.dat

However, if you are using Library Expert Lite you can't adjust the Preferences. Only LE Pro users can do that.

From using the IPC calculator, it seems clear that they licensed a version of Library Expert from you.
I just tried using the latest PCB LE Lite 2017.06 from your webpage, and comparing it to 2016.08 from IPC.

Using a 1005 (EIA 0402) chip, capacitor and putting in the component dimensions the same in the two versions, gets two results.

Do you know if the IPC version will get updated?  I ask, since internally I can justify the IPC calculator (i.e. came from IPC) vs. PCB libraries, as being a private company.  And yes, its clear that its the same product, however, upper management is rather conservative.
