Hey everyone,
The Q1 Testnet reset is scheduled for March 15, 2023 at 0900 UTC.
A reset clears all ledger entries and historical data from both Stellar Core and Horizon. After the reset, you will need to recreate Testnet accounts, assets, offers, liquidity pools, and any other ledger entries you rely on, and this warning should give you some time to figure out how.
