. V2014 will be released tonight. For Standard Packages use IPC-7351 land patterns. For unique one-of-a-kind package use the mfr. recommended pattern

. Is it done intentionally? There is no automated way to draw footprints for PLCC2 package (LEDs). And most importantly, I have yet to find a component for which manufacturer recommended footprints and your calculated footprints match
