Some notes on dev mode
Dev mode is a boolean that can be set in the genesis file.
This is read into the Genesis struct in data/bookkeeping/genesis.go.
This is also recorded to the full node config AlgorandFullNode.
When in dev mode, the node factory MakeFull in node/node.go will initialize a frozen clock for the dev mode node.

Some thoughts to keep in mind when developing PyTeal smart contracts. Hopefully, these points will make it easier for reviewers and auditors to read and understand the contract logic.
Since PyTeal is still under active development, there may be bugs fixes or patches in future versions. Although specifying the exact compiler version is likely the best practice, allowing minor version bumps through the caret (^) seems acceptable too.
