I just noticed that on July 23 the US FDA approved the 2nd generation Libre that has 14-day wear and
a 1-hour warmup. https://www.accessdata.fda.gov/cdrh_docs/pdf16/P160030S017a.pdf
Supposedly it’s expected to become available by the end of 2018. No alerts, so not yet a full CGM unless you go with a “we’re not waiting” solution. Lots more details on features can be found at https://www.healthline.com/diabetesmine/freestyle-libre-14-day-wear
