The 440.15 fw supports an updated (new features) Chilipeppr widget which significantly enhances the use of multiple coordinate systems. The creation of this new widget found a bug in 440.14 that is corrected in 440.15.
440.15 was created and is supported by Danal, has been tested and works for those who have tested it so far. If you upgrade to 440.15 and don’t like it, yes, you could reinstall 440.14 from Synthetos.
You do have the option to run CP with 440.14. Unfortunately, I can’t be explicit as to the specific case where the bug (fixed in 440.15) will nip you.
I’ll ask Danal to address that, in this thread:
