_byVersion
mapping(bytes => address) _byVersion
abi encoded version -> implementation address we use bytes here so only a single storage slot is used
getByVersion
function getByVersion(uint8[3] version) external view returns (address)
get an implementation by a version tag
Parameters

| version | uint8[3] | [major, minor, patch] version tag |
Return Values
| Name | Type | Description |
|---|---|---|
| [0] | address | implementation associated with the given version tag |
hasVersion
function hasVersion(uint8[3] version) external view returns (bool)
check if a version exists
Parameters
| Name | Type | Description |

Return Values
| Name | Type | Description |
|---|---|---|
| [0] | bool | true if the version is registered |
