From Stellar's slack:
"FYI everybody - Stellar Validators have decided that tomorrow at 10AM pacific time the base reserve will be reduced to 0.5 XLM from 10 XLM. What does it mean? You don't need 20 XLM to create an account, but 1 XLM; additional entries like trust lines require an additional 0.5 XLM instead of 10 XLM. I just ran the same command that operators have scheduled for tomorrow on testnet so testnet is already running with the reduced reserve."
