When did the direction of the E1 offset on SIP packages get flipped? 

It bit me on a new design, where a regenerated footprint had a mirrored layout. 

I think the new way is OK, I was just surprised.

The E1 dimension is for the 'Offset' from the center. 

If the pins are centered, do not enter a E1 dimension as it's Optional. 

There is no SIP 'Mirror' feature in the current V26.07 release.

The direction of the offset was flipped between 2025.04 and 2026.08. The same FPX gives different footprints. I was wondering when it happened.
