I have updated my testnet to hived rev f74d4f3. In addition, I also created a docker image, thanks to @someguy123's excellent hive-docker tools (docker image: inertia/hive:master-testnet).
This testnet blocklog has been reset, so if you have previously sync'd to my testnet, you will need to clean out your copy and start a fresh sync, like the very first time.
I was hoping not to have to completely restart the blocklog and just pick up where I left off, with only the hived binary being updated. But something went wrong and I'm not sure what. However, it's common to restart a testnet like this anyway. Normally, Hive testnets have a hard limit of 90 days.
Maybe next time, I'll try out the new state-files load/restore options.
