@jackzampolin Can we add #2576 as well (it's R4R)? otherwise we'll have to use hardcoded values for the gov params on Voyager

[jaekwon]

stake bond denom refactor cannot be merged for 9001. Also that PR isn't complete, so, will do for GoS instead.

[bneiluj]

gaia-9001 is down due to Consensus Failure.

Would be great to fix excessive logging of "Send failed" as well: https://github.com/tendermint/tendermint/issues/1817

I'd recommend logging as "debug" level or not at all. Logging "Send failed" with error severity seems wrong, provides little operational information and makes logs fill up quickly.

[alexanderbez]

@mdyring yes, we've discussed this along with a few other logging tweaks. I wouldn't say it's critical to get in, but certainly if we can!

[alexanderbez]

@jackzampolin @gamarin2 do we want gas uint (#2839) in for GoS? I believe it's ready.

v0.27.0 just got cut. Closing this issue.
