I basically recommend that you listen to the whole thing, usually it's pretty easy to tl;dr but on this one we talk about a lot of various subjects that are basically dev/testnet sync.
Topics touched upon
Dev sync
Testnet sync
future testnet that mirrors the main net even more closely
List of tests/cases to focus on for remainder of testing.
State of libraries/key dapps/services ahead of HF -- ready?
as always if you have questions, feel free to ask them in the comments :)
