Release 2019.07 - RC1 almost complete

Dear RIOTers, ||We have almost completed RC1 testing for the upcoming release. If there

are any recentbug fixes that you believe should be included please back-port them so they can be included in RC2 testing. I intend to start RC2 tomorrow (19.07.2018). Please ping me if you need any help with backporting (@MrKevinWeiss) Best regards, Kevin Weiss|
