SN74LVC161284DLR Digi-Key part number: cut tape packaging discontinued at Digi-Key, use tube packaging instead.
Fix 40-pin and 26-pin headers, accidentally picked 2 mm pitch parts instead of 2.54 mm pitch parts.
The last fix, that was due to an interesting misguided assumption when searching for parts. I should have realized that 2.54 mm pitch pin headers weren't the only game in town for these larger connectors. Now that I look carefully, I see there's all kinds of interesting variations.
Fix capacitor quantity in v4.
