#### libwasmvm update

Our dependencies have been updated. Now the binary requires `libwasmvm v1.5.0`. When you build the binary from source on the server machine you probably don't need any change.

Exchange rates receiving fewer than `VoteThreshold` total voting power have their exchange rates deleted from the store.

A `VotePeriod` during which either of the following events occur is considered a "miss":

- The validator fails to submits a vote for **each and every** exchange rate specified in `AcceptList`.

- The validator fails to vote within the `reward band` around the weighted median for one or more denominations.
- Validators don't provide enough price votes for a given denom (ballot denom support is less than the required `VoteThreshold`) - **in that case all validators will receive a miss.**

A `SlashWindow` is a window of time during which validators can miss votes. At the end of this period, the amount of misses are tallied and the proper reward or punishment is carried out.
