Protocol : Upgraded contracts are removed from resolver cache.
Contract : Verify phase is now optional.

Example Read-only transaction

{
    "$tx": {
        "$namespace": "namespace",

BREAKING CHANGES

Network: Busy Locks & Network Stable errors no longer return as status code 500 instead it is now 200. This was done to bring them inline with other errors within Activeledger (Such as contract errors). If you're using one of the SDK's not many changes should be needed because the returned summary values will be blank apart from the error property. An example error response will look like :

{
    "$umid": "",
    "$summary": {
        "total": 1,
        "vote": 0,
        "commit": 0,
        "errors": [
            "Busy Locks"
