# Stargaze V8 Upgrade

This upgrade includes version updates to CosmWasm, ibc-go and the sdk.

- SDK v0.45.11
- Wasmd v0.29.2 (adds cosmwasm_1_1 capability)
- IBC v3.4.0
- Tendermint v0.34.23
- Includes new messages for ICA not present in v7 (IBC Transfer, VoteWeighted)
- Adds ante handler decorator that requires a min deposit of 1,000 STARS (20%) to prevent Spam proposals.

# Details of upgrade time

This proposal suggests block #6014027 for the upgrade, which is estimated to be at Thursday 15th December 16:00 UTC, using avg block time of 5.93 secs https://www.mintscan.io/stargaze/blocks/6014027

When the network reaches the halt height, the state machine of the blockchain will be halted. Cosmovisor, if configured properly, will then switch the binary used for v8.0.0, and then the chain will continue to make progress.

In the event of an issue at upgrade time, we will coordinate via the #verified-validators channel in Discord.
