When did v1 come out?

Does anyone know the date of the very first public release of Expo?

If you go to the npm page for Expo, looks like it was ~6 years ago. Are you looking for a hard date?

the expo package actually used to be owned by someone else, expo was named exponent previously. i believe @ccheever and @ide released their first prototype of exponent around the time this newsletter was published: http://reactnative.cc/issues/2015/08-05-2015.html
