Hi everyone,
I hope you and your families are all safe and healthy during these times, and are adjusting to our "new normal".
Firstly, I wanted to say that I am extremely impressed by the resilience and energy of our community! I'm thoroughly enjoying seeing your activity on Twitter and the SIGs mailing lists.
We didn't have the chance to host the Contributor Summit in March, where we were planning to share the latest and greatest from our community, nonetheless I'm happy to bring more info about the TF SIGs, the documentation community and current RFCs.
Read on for additional updates and details!
Joana, on behalf of the TensorFlow team!
