The API uses semantic versioning.
TL;DR: Given a version number MAJOR.MINOR.PATCH, increment the:
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
Added clef_New to the internal API callable from a UI.
Newcreates a new password protected Account. The private key is protected with the given password. Users are responsible to backup the private key that is stored in the keystore location that was specified when this API was created. This method is the same as New on the external API, the difference being that this implementation does not ask for confirmation, since it's initiated by the user
message field was renamed to messages in all data signing request methods to better reflect that it's a list, not a value.storage.Put and storage.Get methods in the rule execution engine were lower-cased to storage.put and storage.get to be consistent with JavaScript call conventions.Removed password from responses to operations which require them. This is for two reasons,
Approve but require the actual password to be stored in the clef storage.
With this change, the same stored password can be used even if rulesets are not enabled, but storage is.Approve, there's no need for the UI to cache it locally.
clef_storePassword to the internal API, so the user can store it via his UI (currently only CLI works).Affected datatypes:
SignTxResponseSignDataResponseNewAccountResponseIf clef requires a password, the OnInputRequired will be used to collect it.
Changed the namespace format to adhere to the legacy ethereum format: name_methodName. Changes:
ApproveTx -> ui_approveTxApproveSignData -> ui_approveSignDataApproveExport -> removedApproveImport -> removedApproveListing -> ui_approveListingApproveNewAccount -> ui_approveNewAccountShowError -> ui_showErrorShowInfo -> ui_showInfoOnApprovedTx -> ui_onApprovedTxOnSignerStartup -> ui_onSignerStartupOnInputRequired -> ui_onInputRequiredBidirectional communication implemented, so the UI can query clef via the stdin/stdout RPC channel. Methods implemented are:

ShowError, OnApprovedTx, OnSignerStartup be json-rpc notifications:A Notification is a Request object without an "id" member. A Request object that is a Notification signifies the Client's lack of interest in the corresponding Response object, and as such no Response object needs to be returned to the client. The Server MUST NOT reply to a Notification, including those that are within a batch request.
Notifications are not confirmable by definition, since they do not have a Response object to be returned. As such, the Client would not be aware of any errors (like e.g. "Invalid params","Internal error"
3.1.0
ContentType string to SignDataRequest to accommodate the latest EIP-191 and EIP-712 implementations.OnInputRequired(info UserInputRequest) for obtaining master password during startupOnInputRequired(info UserInputRequest) to internal API. This method is used when Clef needs user input, e.g. passwords.The following structures are used:
UserInputRequest struct {
Prompt string `json:"prompt"`
Title string `json:"title"`
IsPassword bool `json:"isPassword"`
}
UserInputResponse struct {
Text string `json:"text"`

Modify how call_info on a transaction is conveyed. New format:

OnStartup method, to provide the UI with information about what API version
the signer uses (both internal and external) as well as build-info and external api.Example call:
