  - Fixed build failure in protobuf host tools build (relaxed compiler
    warning checks).

    OEMCrypto_RewrapDeviceRSAKey() and OEMCrypto_RewrapDevideRSAKey30()

## 3.3.0 (2017-05-03)

Features:
  - Support OEMCrypto V12. Versions 8 through 11 are supported through
    adapters.

  - Add tool for generating Provisioning 3.0 OEM Certificates.
  - Add property (provisioning_messages_are_binary)to control whether
    CDM generates/accepts provisioning messages in binary or base64+JSON
    format (default is base64+JSON).
  - Upgrade Protobuf kit (from 2.5.0 to 2.6.1).
  - Add Cdm::getServiceCertificateRequest() and
    Cdm::parseServiceCertificateResponse().
  - Add API calls for managing usage records:
    - Cdm::listUsageRecords
    - Cdm::deleteUsageRecord
    - Cdm::deleteAllUsageRecords
  - Remove automatic Service certificate fetch from CDM.
    - The CDM client is responsible for ensuring the CDM has a valid
      Service Certificate.
  - Add status return to report that playback is blocked by HDCP or
    video resolution constraints (kKeyUsageBlockedByPolicy).

    - The request message in an
      IEventListener::onDirectIndividualizationRequest() callback.
    - The response message in the call to Cdm::update().
    Conversions and/or filtering required by a particular Provisioning Server
    must be performed in CDM client code.
