## Proposal to Upgrade the Sale Canister for SNS-1
### Proposer: DFINITY Foundation
### Git Hash: a41b7ea5910e8e7607893f028ec794b42ecedc5e
### New Wasm Hash: d090d3de4e909f273ddb2d007682d190fd940d06e880a3c3a996c6c90b581b5a
### Target canister: zcdfx-6iaaa-aaaaq-aaagq-cai
---
This proposal upgrades the SNS-1 Sale Canister to the latest version to keep the API compatible with other Sale Canisters.  
This does not affect SNS operations in any way, as the Sale Canister only interacts with the rest of the SNS before, during, and immediately after a token sale.
## Features
- Adding APIs
- Add optional delay to start of sale
- Guard addition of dapps by proposal
## Release Notes
