@jvanier, I’ve just tried to particle library upload a migrated lib and got this for it on CLI 1.19.1
$\Particle\Adafruit_HX8357>particle library upload
Network error from https://api.particle.io/v1/libraries
That used to work with 1.19.0-libraries.23
Update:
Strangely enough I was able to upload another (smaller) migrated library just fine, but this one doesn’t want to be uploaded for some reason
https://dl.dropboxusercontent.com/u/60050879/Adafruit_HX8357.zip
Update:
I found the reason. One of the examples brings a 450KB demo bitmap along and hence the upload fails. Removing that file allows the upload, but then the demo is only worth half, since the displays wants a R5G6B5 bitmap which not every user may know how to produce one, just for the sake of running the sample.
